TBRIIESTHIAL ISOPOJD CRUSTACEANS. 



389 



Species of Armadilloidean Isopods seem to be numerous in the 

 tropical regions, although they have until now generally escaped 

 the collector's bottle. Their small size (seldom reaching to 

 10 millimetres in length), their dull colour, and above nil the scarcity 

 of individuals have proved a good protection. The species are 

 remarkably localized, and none of the thirteen of which specimens 

 are sent to me have as yet been mentioned by any of the authors 

 who have described Isopods from Central America, the Antilles, or 

 the neighbouring parts of South America ', except A. grenadensis. 



The following species are represented in the collection : — 



1. Armadillo tenuipunctatus, n. sp. 

 Kg. 1. 



1 a. Oephalon and first two segments of pereion (uppereide). 



1 b. Cephalon and first two segments of pereion (underside), p, prosepistoma ; 



/, double-jointed flagellum of antennse ; c, coxopodite. 

 1 c. Fifth segment of pleon, pleotelson, uropoda (upperside). ex, exopodite of 



uropoda. 

 1 d. Ihe same (underside), b, basis of uropoda ; en, endopodite. 



Body rather wide, moderately convex, slightly tuberculated on
