APODAL FISHES OF AMERICA AND EUROPE. 
631 
Habitat: West Dalian fauna, north to Florida. 
Etymology : Latin, ocellate, from the spots. 
Generally common in the West Dalies. We have before us several 
large examples obtained on the Snapper Banks near Pensacola. 
68. OPHICHTHUS UNISERIALIS. 
Ophich thy 8 uniserialis Cope, Proc. Amer. Phil. Soc., 31, 1877 (Bay of Pacasmayo, Peru). 
Habitat : Coast of Peru. 
Etymology : Latin, one-rowed. 
This species is known to us from Cope’s description. 
69. OPHICHTHUS TRISERIALIS. 
Murcenopsis triserialis Kaup, Apodea, 12, 1856 (Pacific). 
Opliichthys triserialis Giinther, vm, 58, 1870 (Pacific ; Caribbean Sea; Bahia); Streets, 
Bull. U. S. Nat. Mus., 55, 1877 (Gulf of California) ; Jordan & Gilbert, 
Proc. U. S. Nat. Mus., 457, 1880 ; Jordan &, Gilbert, Bull. U. S. Fish Com., 
101, 1882 (Mazatlan) ; Jordan & Gilbert, Proc. U. S. Nat. Mus., 37, 1881; 
Jordan &, Gilbert, Syn. Fish. N. A., 359, 1883; Jordan, Proc. U. S. Nat. Mus.. 
370, 1885. 
Heipetoichthys callisoma Abbott, Proc. Acad. Nat. Sci. Phila., 475, 1860 (locality un- 
known). 
Opliisurus calif orniensis Garrett, Proc. Acad. Nat. Sci. Cal., 66, 1863 (coast of Lower 
California). ~ » 
Ophichthus rugifer Jordan & Bollman, Proc. U. S. Nat. Mus., 155, 1889 (Charles 
Island). 
Habitat: Pacific coast of Mexico; Brazil 1 ? 
Etymology: Latin, three-rowed. 
This species is not rare on the Pacific coast of tropical America. It 
has also been accredited to the Atlantic (Caribbean sea ; Bahia) by Dr. 
Giinther. This record needs verification, as perhaps the related species, 
O. havannensis , has been mistaken for it. 
There is no doubt of the identity of Garrett’s californiensis with the 
species commonly called triserialis. The original type of Garrett’s 
description in the Museum of the Academy of Natural Sciences at San 
Francisco has been examined by us. The description of Herpetoiclitliys 
callisoma applies well to the species in question. 
The form called O. rugifer , of which two specimens from Chatham 
Island in the Galapagos, are now before us, seems to differ only in the 
greater length of the pectoral. This is probably due to their youth, and 
we have little hesitation in referring O. rugifer to the synonymy of tri- 
serialis. 
70. OPHICHTHUS GRANDIMACULATUS. 
Opliichthys grandimaculata Ivner & Steindacbner, Sitzgsber. Akad. Wiss. Wien, 389, 
fig. 13, 1866 (Peru, fide Gunther) ; Giinther, vm, 58, 1870 (Peru). 
Habitat: Coast of Peru. 
Etymology : Grandis , large; maculatus , spotted. 
This species is known to us from descriptions only.
