Genus Paralomis White 



Carapace coarsely granulate, tuberculate, or armed with numerous short, often 

 blunt spines; gastric region usually with a strong, sharply pointed spine. Basal 

 (second) segment entire; median plates of third to fifth segments distinct, often 

 separated from one another by a membranous interval, covered by calcified 

 nodules; lateral plates of these segments subequal in both sexes. 



Key to the California Species of Paralomis 



I. Carapace' spiny, particularly marginal, gastric, and rostral regions. Ambula- 

 tory legs angular, not at all compressed, with spines arranged in rows on 

 angles or ridges. (Known only from 625 + fathoms.) 



multispina, p. 159. 

 II. Carapace tuberculated, margins spiny, a single acute spine on gastric region. 

 Ambulatory legs much compressed, anterior and posterior margins set with 

 sharp spines. (Known only from 688 -f- fathoms.)
