1887. Platax brevis, J. W. Davis, Trans. Doy. Dublin Soc. [2] vol. iii. 
p. 524, pi. XXV. fig. 4, [Distorted fish ; Edinburgh Museum of 
Science and Art.] 
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 wEen 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 spines and 19 articulated rays, not extending backwards beyond 
the dorsal fin. 
The type specimen of the so-called Platax brevis is evidently 
somewhat shortened and deepened by distortion.
