Head 2i; depth 3|; D. XI-I, 23; A. II, 9; scales 48 in lateral 

 line to caudal base, and about 15 more out over caudal fin basally; 

 7 scales above 1.1. to spinous dorsal origin; 8 scales below 1.1. to 

 spinous anal origin; snout 4j in head; eye 3f ; maxillary 2^; inter- 

 orbital 4f. Body rather robust, compressed. Head compressed,

 Rakers 9 + 14, iii, lanceolate, 2 in eye. Scales in horizontal rows 

 below lateral linC; above concurrent with its course, except below 

 middle of spinous dorsal when sloping obliquely up under origin of 

 soft dorsal, though concurrent with lateral line rest of space poster- 

 iorly. Rayed vertical fins largely scaly over basal portions. Lateral 

 line concurrent with back, tubes large, bifid. Dorsal spines slender, 

 fifth longest. Soft dorsal inserted about midway between eye

This species appears to be rare or little known. Two examples 

 recorded by Jordan and Eigenmann from St. Thomas indicate the 

 variation.i^ The above characters given very strongly suggest that 

 Corvula sadce-lucice Jordan is identical.
