Type. Imperfect fish : Bheinland Museum, Bonn. 
A species attaining a length of about 0’25. Length of head with

trunk, which is contained between three and four times in the 
total length of the fish to the base of the caudal fin. About 
36 vertebrae, half being caudal. Fins as in L papyraceus, except 
that the dorsal is relatively large, being about as deep as the 
trunk at its insertion.
