" Body short, laterally corapressed, composed of fourteen segments 

 exclusive of the ccphalon. Cephalon small, in great part covered 

 by the fii'st segment of the pereion. Eyes projecting. Superior 

 antennoo large, having a stout peduncle composed of three articxi- 

 lations (the flagellum is destroyed, and there remains only the base ; 

 we see that there is no secondary appendage). Inferior antennae 

 verj^ small, inserted beneath the preceding, composed of a peduncle 

 and a short multiarticulate flageUum. Seven pairs of filiform legs, 

 simple, monodactyle. The gnathopoda f^nd first two pairs of pereio- 

 poda subequal, shorter than the three posterior pairs of pereiopoda, 

 which are also subequal. Three anterior pairs of pleopoda of the 

 ordinary form ; the fourth pair a little smaller, and composed of a 

 peduncle and two little, oval and very short rami. Posterior pair 

 of pleopoda having the peduncle very short, large and round, and 

 tenninating in two small, pointed, oval rami. Telson very short, 

 transversal, and a little rounded." — Guerin-MeneviUe. 



1. Phlias serratus. (Plate XIV. a. fig. 2.) 

 Phlias serratus, Gu6rin, Magasin de Zoohgie, 1836, cla.ss vii. p. 19. 

 " All the segments are dorsaUy very pointed, which gives to the 

 animal in profile a strongly dentate appearance. It is of an opaque 

 yeUow-brown colour.

" M. Gaudichaud found this pretty little species dming a passage

2. Phliaa Rissoanus, n. s. (Plate XlY.a. fig. 3.) P.M. 



Cephalon small. Each segment of the pereion and three anterior 

 segments of the pleon dorsally elevated into a strong, flat, obtuse- 

 pointed tooth, and furnished on each side, near the anterior margin 

 of each segment, with a strong tubercle. Eyes borne on elevated 

 tubercles. Superior antonme carrpng a strong tubercle or blunt 

 tooth near the apex of the first (?) artictdation of the peduncle ; 

 flagellum not longer than the third joint of the peduncle. Inferior 

 antennae scarcely as long as the superior. Gnathopoda (imperfectly 

 examined), Pereiopoda subequal, cylindrical, robust, carrying a 

 short curved dactylos. Pleopoda (imperfectly examined). 



Length rather more than ^,th of an inch.
