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 + fathoms.)
