II. Richardson — Isopods of the Bermudas. 297 



Janira minuta Richardson, sp. nov. 



Plate XXXIX. Figures 50-52. 



Surface of body smooth. Color light j-ellow, almost white, spotted 

 with black. 



Head with frontal margin straight ; eyes large, conspicuous, oblong, 

 and situated at the lateral margin. First pair of antenme with the 

 three peduncular joints equal in length, the first one, however, being 

 very much the broadest, the second a little stouter than the third ; 

 flagellum multi-articulate, composed of about ten or eleven joints. 

 The second pair of antennae have a scale outside the third joint of 

 the peduncle ; flagellum multi-articulate, much longer than the body. 

 Thoracic segments subequal in length. First segment with the 

 lateral margin entire, epimeron not evident from a dorsal view. 

 Second and third segments with margins entire, straight, epimera 

 evident about the middle of the segments. Fourth segment with the 

 posterior half of the lateral margin slightly excavate, the epimeron 

 evident in the excavation. The last three segments Avith the lateral 

 margins entire, the epimera evident as small lobes at the post-lateral 

 angles. 



The terminal segment is about as broad as long, rounded posteriorly 

 with a median lobe between the peduncular joints of the uropoda. 

 The uropoda extend much beyond the terminal segment, being 

 longer than that segment. The outer branch is somewhat shorter 

 than the inner branch ; both branches are longer than the peduncle, 

 and are fringed with long hairs. 



In the female the first pair of legs are prehensile ; the others 

 are simple walking legs, with biunguiculate dactyli. Tn the male, 

 however, the first pair of legs are modified, though prehensile. The 

 carpal joint is very much enlarged and is produced on the inside, at 

 its outer distal end, in a long, acute process, between which and the 

 articulation of the propodus are two long acute processes about half 

 as long as the outer process. The propodus is similar to that of the 

 female ; the dactylus is biunguiculate. 



A number of specimens, both males and females, were collected by 

 A. E. Verrill and paity in 1898, at Castle Harbor, Bermudas. 



Type specimens in Peabody Museum, Yale University. Cat. Xos.
