Type. Imperfect fish ; Geneva Museum. 
A species nearly as large as the type, with the trunk slightly 
deeper in proportion to its length. Pelvic fins when adpressed just 
reaching the anal spines ; dorsal fin with 2 or 3 spines and 29 or 
30 articulated rays, the length of the longest anterior rays not ex- 
ceeding half the depth of the trunk at their insertion ; anal fin with 
3 8 P ln es and 1 9 articulated rays, not extending backwards beyond
