on 19 specimens, unless otherwise stated, ranging in length from 55 to 

 295 mm. (45 to 230 mm, to base of caudal) long, the smaller specimens 

 used being included in R. E, Coker's collection. 



The name "cabinsa," according to the report of the Mission (1943, 

 pp. 25 and 276), is used also for Paranthias jurcijer. As it seems un- 

 likely that P. juTcijer is of much commercial value, it probably is 

 correct to assume that the fish marketed as cabinsa are mostly this 

 species, which seems to indicate that it is of considerable commercial 

 value. The usual size of the fish seen in the market is reported to be 

 about 200 mm., and large ones ranged upward to 300 mm. 



Range. — Coasts of Peru and Chile. 



Genus ORTHOPRISTIS Girard, 1859 



Body rather deep, compressed; back fairly high; head deep, com- 

 pressed; snout usually long, pointed; mouth rather small, low; lips 

 thin; teeth villiform, in a band in each jaw; preopercle usually finely 

 serrate; scales firm, rather small, the series above lateral line not par- 

 allel with it, forming a sheath at base of dorsal and anal, and some- 

 times extending on these fins; dorsal fin not deeply indented, with about 

 11 to 13 spines and 12 to 15 soft rays; caudal fin with a shallow fork; 

 anal with 3 rather small spines, the second not greatly enlarged, and 

 with about 10 to 13 soft rays. 



One species definitely belongs to the Peruvian fauna. A second 

 one, 0. modestus Tschudi (1845, p. 11), has been described from 

 "Peru." However, the description is such that no one has been able 

 to determine whether it is distinct from the species herein described, or 

 from 0. cantharinus Jenyns, originally described from the Galapagos 

 Islands. As it seems impossible to determine what 0. modestus is, no 

 further mention will be made of it.
