618 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
49. MYRICHTHYS PARDALIS. 
Ophisurus pardalis Valenciennes, in Webb & Berthelot, lies Canaries, Poiss., 90, pi. 
16, fig. 2, 1836-1844; Richardson, Erebus and Terror, Fisbes, 99, 1844 (not 
of Giintber). 
? Ophisurus breviceps Richardson, Voy. Ereb. and Terror, 99, 1844-1848 (locality un- 
known) ; (not of Cantor, 1850). 
? Pisoodonophis breviceps Kaup, Apodes, 20, 1856 (same type). 
f Ophichthys breviceps Gunther, vm, 82, 1870 (same type). 
Pisoodonophis coronata Kaup, Aale Hamb. Mus., 14, tab. 2, fig. 1, 1859 ( fide Gunther). 
Habitat : Tropical parts of the Atlantic. 
Etymology: Latin, marked like n, leopard. 
We know this species only from the description of Valenciennes. 
We have ventured to refer to the Atlantic pardalis, the descriptions of 
M. breviceps. They agree equally well with pardalis and tigrinus , and 
the specimen from an unknown locality named breviceps by Richardson is ' 
at least as likely to have come from the Atlantic as the Pacific Ocean. 
Possibly pardalis and tigrinus may prove to be identical, but the markings 
of tigrinus differ from those shown in Valenciennes’ figure. 
50. MYRICHTHYS TIGRINUS. 
? ? Opliisurus breviceps Richardson, Voyage Erebus and Terror, Fishes, 99, 1844 (locality 
unknown). 
Myrichthys tigrinus Girard, Proc. Acad. Nat. Sci. Phila., 58, 1859 (“Adair Bay, Ore- 
. gou”). 
Opliisurus xysturus Jordan & Gilbert, Proc. U. S. Nat. Mus., 346, 1881 (Mazatlan). 
Pisoodonophis xysturus Jordan, Bull. U. S. Fish Comm., 106, 1882 (Mazatlan). 
Habitat : Pacific coast of Tropical America. 
Etymology: Latin, like a tiger (in color). 
This species is rather common on the west coast of Mexico. We 
have adopted the name tigrinus instead of xysturus, as there seems to 
be no doubt that Girard’s type, said to be from “Adair Bay, Oregon,” 
belongs to this tropical species. This locality is, however, very doubt- 
ful, and probably Girard’s specimen came from the coast of Mexico. 
A specimen before us from the old collections of the Museum is, as 
already stated, probably Girard’s original type. It may be that Rich- 
ardson’s breviceps is also identical with xysturus, but it is on the whole 
more likely to be the Atlantic species pardalis. Besides the types of 
M. tigrinus and M. xysturus , we have before us a specimen taken by Dr. 
Gilbert in the Gulf of California.
