West Indies north to Key West; hitherto regarded as only from Havana and Key West. Ninety 
per cent of the specimens of this genus obtained by us are referred to this species. Specimens were 
obtained at San Juan, Aguadilla, Mayaguez, Puerto Real, Guaniea, Ponce, Hucares, Fajardo, and Cule- 
bra; it was exceedingly abundant at Culebra, Fajardo, and Ponce about the coral reefs and around 
the little islets, every haul of the seine securing several. At Fajardo they were particularly common 
among the alga? on the west side of the small keys off the Playa.

completely scaled; lateral line beginning at upper end of gill-opening, arched, gradually approaching 
dorsal outline as it proceeds backward, ceasing under middle dorsal rays; fins moderate; longest dorsal 
spines nearly 2 in head; middle rays of soft dorsal elevated, about 1.4 in head; second anal spine long, 
strong, and gently curved, 2 in head; soft anal similar to soft dorsal, the rays somewhat longer; caudal
