The inferior anteunse (see fig. 13) are somewhat more strongly built 

 than the superior, but scarcely longer, and have the flagellum comparatively 

 small, and 4-articulate. 



The gnathopoda are rather feeble in structure, and densely supplied with 

 bristles, the posterior ones (fig. 17) being a little more elongated than the 

 anterior (fig. 16). The propodos of the latter is oval, of the former oblong 

 quadrangular in form. 



The anterior pairs of pereiopoda are normally developed. 



The 3 posterior pairs, on the other hand, are comparatively short and 

 have their outer part supplied with dense fascicles of slender bristles. The 

 basal joint of the antepenultimate pair is oval in form; that of the penulti- 

 mate pair somewhat larger, and narrowed distally. The last pair (fig. 18) 

 have the basal joint still larger, and of a somewhat irregular oval form, with 

 the posterior edge strongly curved in the middle, and densely setiferous. 



The anterior pairs of uropoda (fig. 1 9) are of normal structure, and less 

 unequal than in the preceding species. 



The last pair of uropoda (fig. 20) are not nearly so robust as in tliat 

 species, and have the outer ramus somewhat attenuated distally, exhibiting 

 a distinct, though rather small terminal joint. It is provided on the outer 

 edge with 4, on the inner with 3 fascicles of slender spines accompanied by 

 a few bristles. The inner ramus is rather small, with a single apical bristle. 



The telsou (fig. 21) is somewhat longer than it is broad, and, as in the 

 preceding species, deeply cleft by a narrow incision. The lateral lobes are 

 obtusely pointed, and carry each 2 lateral, and 2 unequal apical spinules. 



Occurrence. — The above-described specimen was taken by Mr. War- 

 pachowsky in the North Caspian Sea, at Stat. 61. 



Gen. Gmelinopsis, G. 0. Sars, n. gen. 



Generic Characters. — Body much compressed, more or less distinctly 

 tuberculated laterally, and having the posterior part carinated dorsally. 

 Integuments rather firm. Cephalon with an umboniform prominence on each 

 side. Anterior pairs of coxal plates large and deep. Superior antennae longer 

 than the inferior, and provided with a small biarticulate accessory appendage. 

 Oral parts nearly as in the genus Gmelina. Gnathopoda rather unequal, the 

 anterior ones being the stronger. Last pair of pereiopoda with the basal 

 joint strongly expanded. Uropoda of a structure nearly agreeing with that 

 in the genus Amathillina. Telson more or less deeply cleft, with the lateral 

 lobes narrowly pointed.
