sixth, and seventh segments are about equal in length and are a 

 little longer than the second, third, fourth, and fifth segments, which 

 are also about equal. Telson 21/2 mm long by 2 mm wide. The 

 uropods are as long as telson; peduncle is about 11/2 times as long 

 as imier joint, outer joint one-half as long as inner and narrower. 



First pair of antennae has first peduncular joint broader and a 

 little shorter than second, the third joint about one-half as long as 

 second, and a flagellum of 8 articles. Apices of the fifth, sixth, 

 and seventh joints of flagellum have club-shaped setae. The fii*st 

 antennae extend to the end of the fifth peduncular joint of the second 

 antennae. 



Second antenna about 71/2 mm long: the peduncle 2 mm and the 

 flagellum 5i/^ mm. There are approximately 69 joints in the flagel- 

 lum. The first three peduncular segments are about equal in length 

 and together are as long as the fourth segment. The fifth segment 

 is a little longer than the fourth. 



Left mandible with two sets of teeth, each series containing 4 

 teeth; right mandible has only one set. consisting of 4 teeth. The 

 margin below teeth with 12 plumose setae on each of the mandibles. 



Outer ramus of first maxilla with 11 teeth, the 5 innermost being 

 serrate. The inner ramus has 5 long plumose setae. 



Second maxilla consists of 3 lobes, the inner being triangular, the 

 two outer ones squarish. Outer lobe has 20 long setae ; center one 12 

 setae; and inner one 10 pronged setae, numerous long, slender hairs, 

 and a few short, curved ones. 



Inner plate of maxillipeds and second, third, fourth, and fifth 

 articles of palp on inside, thickly fringed with long hairs. 



The first pair of legs are subchelate, with a long, slender process 

 and a shorter bifurcate one at distal end of propodus :ind 2 spines at 

 proximal end. The inferior side of dactylus is furnished with a row 

 of small spines. The carpus has 2 spines and 2 long hairs. The 

 other legs are ambulatory. 



Remarks. — Asellus hohhsi is closely related to A. alahamensis 

 (Stafford) from which it differs chiefly in the proportions of the ar- 

 ticles of the maxillipeds and in the armature of the propodus of the 

 first pair of legs. The last two articles of the maxillipeds in A. alaha- 

 mensis in their relative proportions are half the width of the same 

 articles in A. hohhsi. 



The proi)odus of the first pair of legs in A. alahamensis is armed 

 with 2 triangular processes and 3 spines placed proximal to the 

 processes. A. hohhsi is armed with 2 triangular processes and 2 

 spines placed proximal to the processes. Moreover, in A. hohhsi the 

 distalmost of the two processes is bifurcate, whereas in the published 

 figure of A. alahainensis the corresponding process appears simple.
