secondary ones being obsolete ; but they are ver_v deeply cut, espe- 

 cially at the middle of the carapax. On the gastric region and at 

 the sides these strigge are undulated, and sometimes partially inter- 

 rupted, so as to resemble broad scales. Their edges are scarcely 

 pubescent, and there are only a few scattered setse on the surface. 

 The gastric and hepatic regions are not very distinctly circum- 

 scribed. On the front and sides of the gastric region there are eight 

 or ten small spinules scattered. Lateral margin seven-toothed, ex- 

 cluding the angle of the orbit, which is situated far inward, as in 

 G. orientalis. Rostrum exactly triangular in shape, of the usual 

 breadth, and armed with four very sharp and deeply cut teeth on 

 each side. Spines on the base of the antennulse very long, reaching 

 almost to the tip of the rostrum. Chelipeds of moderate size, armed 

 with small subequal spines regularly distributed; carpus and meros 

 with two or three longer spines within ; hand more slender than car- 

 pus ; fingers parallel, depressed, not gaping, and not toothed. In the 

 ambulatory feet the meros is slender, and ten-spined above ; dactylus 

 with a short, stout tooth on the inner or lower margin. Length of 

 carapax in a male, 0.26; breadth, 0.16; length of rostrum, o.i ; of 

 chelipeds, 0.56 inch. 

 Found at Ousima.

Galathea grandirosiris Stimpson, Proc. Acad. Nat. Sci. Pliila., x, p. 252 

 [90], 1858. 



Carapax evenly convex ; strigose ; strigge about twelve in number 

 between the base of the rostrum and the posterior margin, and cil- 

 iated with short hairs, equaling in length one-third the distance be- 

 tween the ridges. Some of the strigse are interrupted, and that 

 which crosses the posterior part of the gastric region is undulated. 

 Gastric region not circumscribed. Lateral margin nine-toothed. 

 Rostrum greatly elongated ; surface roughened and pubescent ; mar- 

 gins each serrated with about six small distant teeth almost obsolete. 

 Chelipeds stout, roughened with transverse scabrosities and short 

 setose ; two or three spines at the inner apex of the meros and of the 

 carpus ; no spines on the hand ; fingers moderately pilose and not 

 gaping. The surface of the ambulatory feet is ornamented with 

 transverse ciliated striae, about six in number on the meros- joint. 

 Color purple-brown, very dark ; carapax and abdomen above with 

 two longitudinal yellowish-white vittse ; chelipeds with one median 

 stripe ; ambulatory feet transversely barred. Length of carapax in 

 a male (rostrum included), 0.342; breadth, 0.19; length of rostrum,
