2. ARCHOSCION REMIFER. 
Isopisthus remifer Jordan & Gilbert, Bull. U. 8. Fish Com., 1881, 320 (Panama). 
Habitat.—Pacific coast of tropical America, Panama. 
This species is extremely close to Archoscion parvipinnis, differing only 
in the characters mentioned in our analysis. It may perhaps prove a 
geographical variety of the other. 
3. ARCHOSCION PARVIPINNIS. 
Ancylodon parvipinnis Cuy. & Val., Hist. Nat. Poiss., v, 84,1830 (Cayenne). Giinther, 
Cat. Fish. Brit. Mus., ii, 312, 1860 (copied). 
Tsopisthus parvipinnis Jordan, Proc. Acad. Nat. Sci. Phila., 1883, 289 (Cayenne, re-ex- 
amination of type). Jordan, Proc. U.S. Nat. Mus., 1886, 588 (name only). 
Isopisthus affinis Steindachner, Denksch. Mat. Nat. Kais. Acad. Wiss., 1879, 43, plate 2, 
fig. 2 (Porto Alegre). 
Habitat.—Coasts of Brazil, north to Cayenne. 
Only the original type of this species in the Museum of Paris has 
been examined by us. This seems to be identical with the species well 
figured by Steindachner under the name of Jsopisthus affinis, and from 
Steindachner’s description and figure our account has been chiefly 
drawn.
