convex serrate palm, abruptly descending to form a cavity, within 

 which the apex of the strong curved finger meets a transverse row of 

 spinules and some palm-defining spines. Whether the cavity is open 

 on both sides it is difficult to say. Possibly the finger rests against a 

 transparent cuticle on one side. 



The first peraeopod is rather longer than the second. The third is 

 distinguished from the two following pairs by the slenderness of its 

 second and fourth joints, the fourth joint in the last two pairs being 

 extended completely over the fifth joint. 



The first uropods are as usual much the longest ; the second are 

 intermediate in length. The third pair have the peduncle longer than 

 the ramus, of which the first joint is longer than the almost spine-like 

 second. 



The telson, only seen in uplifted lateral view, appears to have a 

 single pair of lateral spinules.

In 1849 Dana presented to the American Academy of Sciences 

 his description of a new genus and species which he called 

 Lepidopus armatus. The account was published in the Pro- 

 ceedings and also in the thirteenth volume of the U.S. Exploring 

 Expedition. To the text of 1853 figures were added in 1855 on 

 pi. 95 of the Atlas. The generic name being preoccupied, 

 Steenstrup and Liitken in 1861 changed it to Perissoput, a genus 

 which they instituted for P. dentatus n. sp., including with
