D. callipygus, sp. n., Hesse, p. 58, in Ascidia venosa. D. deflexus, sp. n., Hesse, p. 58, found under the cortical envelope of a zoophyte attached to the legs of Maia sqinado. D. oblongus, sp. n., Hesse, p. 59, in Polydinium stellatum. D. rotundus, sp. n., Hesse, p. 60; in Ascidia aspersa. b. Posterior prolongation of the pereion nil. Doropygus verrucosus, sp. n., Hesse, p. 61, in Ascidia venosa. D. albidus, sp. n., Hesse, p. 61, in Ascidia intestinalis. D. viridis, sp. n., Hesse, p. 61, in Cynthia microcosmus. D. gibbosus, sp. n., Hesse, p. 62, in Ascidia intestinalis. D. tumefactus, sp. n., Hesse, p. 63, in a brown pustulated Ascidian attached to Maia squinado. II Extremity of the pleon terminated by a small cavity. Terminal appendages curved and sharp-pointed. a. Posterior prolongation of the pereion large. Doropygus gibber (Thorell), Hesse, p. 63, in Ascidia canina. b. Posterior prolongation of the pereion small. Doropygus acutus, sp. n., Hesse, p. 64, in a yellow Ascidian. D. reflexus, sp. n., Hesse, p. 65, in Ascidia venosa. c. Posterior prolongation of the pereion nil. Doropygus macroon, sp. n., Hesse, p. 66, in a green Ascidian. D. rufescens, sp. n., Hesse, p. 67, in a Eucaelinus. D. coccineus, sp. n., Hesse, p. 67, in a yellow Ascidian. Dysportius striatus (Thorell), Hesse, p. 69, on a sponge and on Rhodymenia palmata. D. marginatus, sp. n., Hesse, p. 71, at the base of a compound Asoidian. Gastrodes viridis, gen. et sp. nov., Hesse, p. 73, pl. iv. fig. B-B 4, in Ascidia intestinalis. Length 2 millimetres, and closely resembles, Botachus. The cephalon is small and elongated. Basal joint of antennaae robust, supporting a cylindrical flagellum consisting of eight articuli. The frontal border of the cephalon is produced into a large rostral-like plate, which is rounded at the apex, and reaches as far as the distal extremity of the basal joint of the antennaae. The pereion consists of six somites, and grandually increases inferiorly and posteriorly, so as to form a large cavity in which the ova are lodged. The pleon is straight and cylindrical, and consists of five somites, of which the posterior is terminated by four small hooked spines which antagonize with each other so as to form pincers. The first pair of legs, situated at the base of the antennoe [these must be the second pair of antennoe], are long and robust, and terminate in a strong hook. These are followed by the short oral appendages and four pair of biramose append-ages. Eye central, anterior, and single. Male and young unknown. Ceratrichodes albidus, gen. et sp. nov., Hesse p. 75, pl. iv. fig. A-A 11, in a social Ascidian. Male. Length scarcely a millimetre. Animal gradually decreasing from the cephalon to the extremity of the pereion. Cephalic buckler equal in? length to the three following somites; the frontal margin is round; following the cephalon are six somites of equal length, of which the posterior is cordiform; behind this is the pleon, which consists of eight somites of subequal length, except the posterior, which is as long as the four preceding; the last somite supports a pair of long narrow flat appendages, furnished with two long and two short spines. On the inferior central margin is a small lobe that is surrounded by a projecting margin; in the centre of this is a point that is perhaps an eye, on each side of which is an antenna belonging to the first pair. They are very large, cylindrical, consisting of 7 or 8 articuli, of which the first, or basal, is the largest. At the base and beneath these antennae are two broad flat ciliated plates [second pair of antennae], the anterior margin of which is furnished with two or three single articuli, furnished with cilia. The oral apparatus is a little posterior to the antennae, and the pereiopoda consist of four biramose pairs. seen laterally the posterior somite of the pereion shows a large ovate opening on each side, of which the margins are furnished, one with two teeth, the other with one, that corresponds in position with the space between the two. These openings appear to be genital orifices, and are surrounded by a membrane which enlarges or contracts itself at need. The female is smaller than the male, and resembles it dorsally, except in the length of the pleon, which is reduced to two somites, and furnished with short stout caudal appendages. Ophthalmapachus ruber, gen. et. sp. nov., Hesse, t. vi. 1866, p. 80. fig. F-F1, in a red compound Ascidian. This genus closely resembles Biocryptes and Hypnodes. The animal is robust, and gradually diminishes from the cephalon to the posterior extremity. In the male the cephalic buckler is less large and narrow anteriorly than posteriorly. The frontal border is round. The pereion consists of five nearly equal somites, followed by five other subequal somites, of which the last is the largest, and terminates in a pair of flat appendages. The eye is placed dorsally in the centre anteriorly. Antennae very large, cylindrical, truncated at the extremity, consisting of three or four articuli furnished with flexible hairs. Immediately-below the antennae is a large flattened jaw-foot [second pair of antennae], furnished at the extremity with rigid hairs. Pereiopoda four pairs, short, robust, biramose. Female shorter and stouter than the male. Patythorax albidus, gen. et sp. nov., Hesse, p. 82, pl.-iv. fig. D-D 1, in a brown pustulated compound Aecidian attached to Maia squinado. Female. Length 3 millimetres, breadth 1 1/2. Cephalic buckler short and rounded anteriorly. The first somite of the pereion ia small, the next two are subequal, and the last is large and deep, equal in length to the three preceding. On each side is a transparent lobe containing the genital apparatus and intended for the reception of the ova. Pleon short and cylindrical Antennae short, cylindrical, consisting of 12 articuli. Cephalon small and rounded anteriorly and depressed. Pereiopoda biramose, and much resembling in form and position those of Notopterophores. Lephosphilus labrei, sp. n., Hesse, p. 278, found on the Green Wrasse.
