AGTINOPTEKYGII. 
Rays of pelvic fius, when adpressed, extending beyond the anal 
spines; dorsal fin with 3 or 4 spines and 22 or 23 articulated rays, 
of which a few are excessively elongated anteriorly, the length 
of the longest at least equalling the depth of the trunk at its 
insertion; anal fin with 4 spines and about 18 articulated rays, 
extending backwards for the length of two vertebrae behind the 
dorsal fin.

P. 4743. Type specimen, very imperfectly figured by Davis loo. cit. 
and erroneously ascribed by him to the so-called Plataos 
minor. The sharply-pointed supraoccipital crest is con¬ 
spicuous, and the comparatively small eye is indicated 
by a black stain. The cleft of the mouth is shown to be 
very oblique, and the maxilla is clearly expanded behind. 
Ten branchiostegal rays are preserved in position below the 
smooth opercular apparatus. 10 abdominal and 14 caudal 
vertebrae can be counted. The pectoral fin is small, com¬ 
posed of very delicate rays ; a long, slender postclavicle 
extends backwards and downwards beneath it to the 
ventral border. The comparatively stout rays of the 
pelvic fins are adpressed to the ventral border and overlap 
the anal spines. Four or five anterior articulated rays of 
the dorsal fin are excessively elongated, forming a peak 
in the front part of the fin, which rapidly becomes quite 
low in its hinder half. The low anal fin, with at least 3 
gradually lengthening stout spines and 18 articulated rays, 
extends backwards for the length of two vertebrae behind 
the dorsal fin. The middle rays of the caudal fin are very 
short and rather sparse; this fin being deeply forked 
and with sharply-pointed lobes. The scales are not 
distinct. Lewis Coll,

characters of the genus and species, but with elevated 
portion of the dorsal fin destroyed. Lewis Coll.
