Hypoplectrus 



M. camelopardalis is a rare species known only from Havana and 

 resembling M. tigris, but the ground colour is bright red. 



The genus Cratinus, which resembles Serranus, has but one 

 species, C. agassi^i, which occurs about the Galapagos Islands. It 

 reaches 18 inches in length and is peculiar on account of its long, low 

 head. 



The genus Hypoplectrus has the body more compressed and 

 deeper than in other groups allied to Serranus. The skull differs from 

 Serranus in the development of the supraoccipital crest, which is much 

 elevated. 



Many species have been described, but they nearly all may be 

 simply colour forms of one, H. unicolor. 



This species, with its various forms, occurs from the Florida Keys 

 southward among the West Indies and to Brazil. 



H. lamprurus occurs at Panama and is a rare species. H. gemma 

 was described from Garden Key, Florida, and is a doubtful species. 



The genus Paralabrax has the body robust and covered with 

 ctenoid scales; mouth large, with small lateral canines and no depressi- 

 ble teeth; smooth area on top of head very short and small, not ex- 

 tending much behind the orbits; the long and low supraoccipital crest 

 extending well forward to a line connecting the postfrontal processes; 

 caudal fin always lunate; some of the anterior dorsal spines considera- 

 bly elevated; dorsal usually X, 14; anal III, 7.
