1896.] TERRESTRIAL ISOPOD 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 all 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 :—
