and the uropods imperfect. The outer branch of the latter in being four-jointed agrees 

 with Hansen's description of his Apseudes intermedins, though his figure represents this 

 branch as five-jointed. The Wasin species has the telsonic segment parallel-sided, without 

 the two blunt processes on each side that occur in Hansen's species. Our specimen has 

 a six -jointed flagellum to the second antennae, and respectively one, three, and four spines 

 on the fourth, fifth, and sixth joints of the second gnathopods. Hansen founded his 

 species on two female specimens with half developed marsupium, their length being 

 2 - 3 mm., flagellum of second antennae four-jointed, spines one, two, and four on the 

 above-named joints of the second gnathopods. Though the very small size suggests 

 specific identity between the Cape Verde specimens and the present form from East Africa, 

 details of structure do not warrant their union. 



KALLIAPSEUDES, n. g. 



Plumose setae extensively developed on large fourth joint of second antennae, on fifth 

 joint of first gnathopods, and on palps of mandibles and maxillipeds. Maxillipeds with 

 the terminal sixth joint the longest. Finger of second gnathopods not apically narrowed, 

 its round end encircled by setae. Fingers of first and second peraeopods very elongate, 

 curved, acute, of third and fourth short, straight, apically blunt, of fifth like those of the 

 first and second pairs, but much shorter. Pleopods with inner ramus much longer and 

 broader than the outer. , 



The generic name is compounded of KaMos, beauty, and Apseudes, the designation 

 of the closely allied genus, from which it is however strikingly distinguished by the group 

 of characters above given. It is possible that others may be added, whenever opportunity 

 offers for a more satisfactory examination of the mouth-organs, but the palps of the 

 maxillipeds are of themselves sufficient to mark a new genus. 



2. Kalliapseudes makrothrix, n. sp. (Plate 5.) 



Cephalic segment areolated, front obtuse, lateral angles without eyes or separated 

 eye-lobes. Penultimate and antepenultimate segments of peraeon the longest, pleon not 

 much narrower than peraeon, its first five segments with rounded setiferous lateral margins, 

 these and the peraeon segments furnished each with a medio-ventral spine. The telsonic 

 segment broader than long, the lateral margins convex to the insertion of the uropods, 

 then narrowing to a bluntly triangular area, a little more than a third of the total 

 length. 



First antennae. The large first joint more than twice as long as the two successively 

 smaller following joints combined ; flagellum not more than half as long as peduncle, its 

 first joint common to the two flagella, but more produced on the inner than the outer side, 

 the outer flagellum with six, the inner with three, additional joints. 



Second antennae. These just reach the flagella of the first pair, by the broad bases 

 of which their peduncles are almost completely concealed. The first joint is produced on 

 the inner side to a setiferous process, possibly an epipod in coalescence. A corresponding 

 process is found in some species of Apseudes, but apparently less developed than here. 

 The second joint, broader than long, has on the outer side a narrow exopod bearing four
