35, anal with nor more than 30 articulated rays ; each probably with 
four anterior spines. 
According to Bassani (communicated MS.), the type specimen 
exhibits about 36 articulated rays in the dorsal fin and not less than 
27 in the anal fin. The number of spines is uncertain.

49583, P. 4862. Two distorted large specimens, the first with 
traces of ova, the second erroneously referred by Davis 
Joe. cit. to Imogaster auratus. In the second, there seem 
to be four anterior spines distinguishable both in the 
dorsal and anal fin. Lewis Coll.

Type. Nearly complete fish; British Museum. 
A small species, attaining a length of about 0*07. Length of 
head with opercular apparatus considerably less than maximum 
depth of trunk, and contained twice in length from pectoral arch to 
base of caudal fin ; maximum depth of trunk less than its length. 
Fins as in the type species.

48112. Type specimen about 0*07 in length. The cleft of the mouth 
is indicated below and in front of the very large orbit, 
and the head is clearly covered with scales. The vertebrae 
are distinctly 12 in the abdominal, 18 in the caudal region ^ 
the ribs are stout, not reaching the ventral border. There 
are fragments of the paired fins, and the characteristic 
median fins are well preserved. Traces of stout free fin- 
supports are seen, as usual, in advance of the dorsal fin. 
The lateral line is arched like the back. The scales are 
quite smooth. Lewis Coll.
