and from all theother species of the genus, it differs inthe shape of the hands. The specimen is a female; 

 but the large hand is as broad and heavy and the palm is as short as the hand of the male of any other 

 member of the genus. 



The species has been named in honor of Dr. J. S. Kingsley, to whose interest and industry much 

 of oiu: knowledge of the Beaufort crustaceans is due. 



Family OGYRIDAE nov. 



Caridea having the first two pairs of legs chelate but of nearly equal size and not 

 much, if any, larger than the other legs, the carpus of the second legs subdivided, the 

 rostrum small or wanting, the eyestalks long, slender, and fully exposed but with the 

 retinal surface reduced, the telson thick and obtusely pointed, the blades of the uropods 

 curved outward, a thelycum present in the female. 



The family thus characterized is coterminous with the genus Ogyris and, probably, should stand 

 between the Crangonidae and Hippolytidae. Couti^re, holding that Ogyris, Automate, and Pterocaris 

 are closely related and that Automate is unquestionably akin to Crangon, places Ogyris in the family 

 Alpheidae (= Crangonidae). It is evident, however, that Coutifere had based his conclusions on the 

 descriptions and figures of other writers without having had an opportunity to examine specimens of 

 either Ogjifu or Pterocaris and perhaps Automate also. Ortman, who had seen specimensof Ogyris, placed 

 the genus in the family Hippolytidae. None of these observers appears to have noticed the presence of 

 a thelycum in the female. Having before us representatives of Ogyris and Automate, as well as several 

 typical genera of both the families mentioned, we have come to the conclusion that Ogyris differs too 

 greatly and in too many characters to admit of our placing it in either family. Its resemblance to Auto- 

 mate is very slight, and it appears also to be very different from Pterocaris.

Ogjnris alphserostris Kingsley. PI. xxvi, fig. 9. 

 Ogyris alphtzrosiris Kingsley, 1880, p. 420. 

 Cephalothorax about half as long as abdomen, the carapace thin, polished, sparingly pubescent, 



lightly grooved and with a rather strong, movable spine on the median line a little behind the very small 



rostrum. Eyestalks about half 

 as long as carapace, rather broad 

 at base, becoming almost thread- 

 li'ke distally but with the tip 

 enlarged. Basal article of an- 

 tennule with a strong external 

 and a smaller superior spine, 

 the entire peduncle about four- 

 fifths as long as eyestalk; flagel- 

 la of equal length. Antennal 

 peduncle shorter than that of 

 the antennule ; fiagellum slender 

 and about twice as long as cara- 

 pace; scale lanceolate, extend- 

 ing to the distal end of second 

 article of antennular peduncle. 

 Third maxillipeds pediform, 

 stronger and longer than any of 

 the legs.their tips considerably 

 exceeding the eyes. Legs all 

 slender, alike on the two sides,
