Type. Small distorted fish ; British Museum. 
A species of moderate size, attaining a length of about O’17c 
Length of head with opercular apparatus greater than the maximum 
depth of the trunk, and occupying more than one-quarter of the 
total length of the fish. The rugose ornament of the head and 
opercular bones very feeble or absent; maxilla comparatively robust, 
ornamented with delicate, longitudinally directed rugae; preoper¬ 
culum with few short, radiating ridges. Pelvic fins arising far in 
advance of the middle point of the trunk, and opposed to the dorsal 
fin. Scales of moderate size, smooth, the hinder margin strongly 
though finely serrated, and the sharp points passing into con¬ 
spicuous crenulations when the surface is partly abraded ; about six 
longitudinal flank-series deeper than broad; lateral line forming 
a feeble ridge. ^
