276 AiiruiroDA xoioialia. 



1. Cratippus temiipes, n. s. (Plate XLVI. fig. 10.) B.M. 



Eyes round, black. Antcnnoc subcqual : superior paii' about onc- 

 foiu'th the length of the animal ; first joint robust, second and 

 third gradually smaller ; flagellum rudimentary, consisting of but 

 three articuli : inferior pair having the last three joints of the 

 peduncle gradiially decreasing in length ; flagellum rudimentary, 

 consisting of only three articuli. First pair of gnathopoda slender, 

 long, scarcely subchelate : second pair lia\-ing the carpus shoi't ; 

 propodos long, as long as the cephalon rnd first segment of the 

 pereion, with the superior and inferior margins parallel : on the 

 right side, the inferior angle is formed into a hollow cup : on the 

 left are two short distal teeth. Pcreiopoda subequal, very long 

 and slender, basa not dilated ; propoda of the three posterior pairs 

 serrated on the inner margin. 



Length ^ths of an inch.

10. DRYOPE, n. g. 

 Unciola, Gosse, Marine Zool. i. p. 141 (not Say). 



Animal long and slender. Superior antennae without a secondaiy 

 appendage ; inferior antenniB not longer than the superior. Coxae 

 not so deep as the pereion. First pair of gnathopoda larger than 

 the second, subehelate ; second pair small, imperfectly chelate. 

 Posterior pair of pereiopoda longer than the others. Posterior pair 

 of pleopoda short, almost rudimentary, double -branched. Telson 

 single, squamiform. 



This genus differs from UncloJa of Say in the absence of a second- 

 aiy appendage to the superior antennae, in the form of the second 

 pair of gnathopoda, in the shortness of the posterior pair of pleopoda, 

 and in the character of the telson. 



1. Dryope irrorata. (Plate XLVII. fig. 1.) B.M. 



Unciola irrorata, Gosse, llarine Zool. i. p. 141. f. 256 (not Sai/). 

 Posterior margin of the second and tliii'd segments of the pleon waved. 

 Eyes round, small. Superior antennae nearly half the length of 

 the animal ; flagellum not longer than the last joint of the peduncle. 

 Inferior antennae scarcely shorter than the superior ; the pedimcle 

 slightly shorter than the peduncle of the superior ; flagellum not 

 longer than the last joint of the peduncle. Fii-st pair of gnatho- 

 poda larger than the second, having the carpus continuous with the 

 propodos, the postero-inferior angle produced to a blunt, posteriorly-
