The superior anteunfo (fig. 3) are rather elongated, considerably exceed- 

 ing in length Yg of the body, and are but sparingly setiferous. The 1st joint 

 of the peduncle is a little longer than the other 2 combined, and has below 

 3 distant spiuules. The flagellum about equals in length the peduncle, and 

 is composed of 1 2 articulations. 



The inferior antennte (see figs. 1 and 4) are rather strongly built, though 

 scarcely exceeding half the length of the body. The penultimate joint of the 

 peduncle is considerably tumefied, almost fusiform in shape, and is produced 

 at the end posteriorly to a very long and slender, mucroniform projection 

 extending be\'oud the middle of the last joint, and having at the base a small 

 secondary tooth. The last peduncular joint is somewhat sliorter than the 

 penultimate one, and, as usual, much narrower, being cylindric in form. It 

 is armed near the base posteriorly with a short recurved prominence, but 

 has not any spiniform process at the end. The flagellum is a little shorter 

 than the last peduncular joint, and of the usual structure. 



The gnathopoda do not exhibit any peculiarity whatever. 



The 2 anterior pairs of pereiopoda (fig. 5) are moderately strong, with 

 the basal joint pronouncedly laminar, and the meral joint considerably ex- 

 panded distaliy, its anterior edge being clothed with scattered slender bristles. 

 The 2 outer joints are not very slender, and the dactylus is about the length 

 of the propodal joint. 



The last i)air of pereiopoda (fig. 6) are about lialf the length of the body, 

 and arc prominently distinguished by the unusual shape of the outer joints, 

 which, instead of being linear, are rather broad and compressed, and edged 

 with fascicles of delicate bristles. 



The uropoda and telson (see fig. 7j do not diifer much from those parts 

 in the other species. 



The pigmentation of the body is the usual one, though it is less con- 

 sjjicuous than in C. rohiistum. 



Occurrence. — Of tliis species some specimens, chiefly of the male sex, 

 were collected by Mr. Warpachowsky at Stat. 63, in the eastern part of 

 the North Caspian Sea. Solitary specimens were, moreover, taken at 2 otlier 

 Stations (St. 53 and 56) north and west of the island of Kulaly. 



In the collection of Dr. Grimm there are a few badly preserved speci- 

 mens, collected i)artly in tlie Eay of Baku, partly in the bay of Balcliansky 

 from comparatively shallow water.
