Mippolyte picta, no v. sp. 



Carapax and rostrum as in H. sitchaensis Brandt (Sibirische 

 Reise, Zool., p. 116; pi. v, f. 8), the latter reaching a very little 

 beyond the peduncle of the antennnlse, and armed with six teeth 

 above (including two on the carapax) and three teeth below, near the 

 extremity. On the antennulse the outer flagellum has the slender 

 part only one-fourth as long as the thick part ; the inner flagellum is 

 one-half longer than the outer. The external antennte are one-third 

 longer than the body. The external maxillipeds reach a little beyond 

 the tip of the antennal scale, and are provided with a flagellum or 

 epignath, but have no exognath. Feet of the first pair provided with 

 an epipod ; those of the last pair rather long and stout ; abdomen 

 smooth ; last segment with four pairs of dorsal aculei. 



Thorax obliquely streaked with crimson. Length of the largest 

 specimen, 1.33 inch. 



It differs from II. sitchaensis Brandt in its longer external 

 maxillipeds and non-carinated abdomen. The rostrum is longer 

 than in H. jjalpator, but much shorter than in //. Zayi. 



Found at Monterey, Cal., by A. S. Taylor, Esq. 



Mipidolyte vitoraais, nov. sp. 



This species resembles very closely II. Phipjysii Kroyer 

 (Monog. Fremst. Hippol., p. 100, pi. iii, fig. 65-68), but differs 

 ill having but one spine over the eye, and only two or three 

 teeth beneath the tip of the rostrum. The carina of the cara- 

 pax is sufiiciently well marked toward the base of the rostrum. 



Found in Massachusetts Bay.
