Family OPHICHTHYID/E. 
34. Myrichthys tigrinus Girard. CuLEvVRA. 
Not uncommon in the harbor of Mazatlan, where sev- 
eral specimens (types of Ophichthys xysturus Jordan & 
Gilbert) were taken by Dr. Gilbert. Several specimens 
were also obtained by us. It has been recorded also from 
Acapulco and Panama. The original types of JZyrich- 
thys tyrinus were said to come from Adair Bay in Oregon. 
It has, however, not yet been taken north of the Gulf of 
Calitornia, and the locality assigned to the type is very 
doubtful. We have not been able to find a bay of this 
name on any map of Oregon. 
35. Ophichthus triserialis (Kaup.) ( Ophzsurus califor- 
niensis Garrett; Herpetorchthys callisoma Abbott.) 
Recorded by Gilbert from Mazatlan; not seen by us. 
A specimen certainly belonging to this species bas been 
lately obtained by Dr. Gilbert in the Bay of Monterey. 
The only other definitely known localities are Cape San 
Lucas and the Galapagos Islands, whence it was de- 
scribed as Ophichthus rugifer Jordan & Bollman. 
36. Ophichthus zophochir Jordan & Gilbert. 
Rather common in the Bay ot Mazatlan, where it was 
also taken by Dr. Gilbert. We have examined specimens 
from Acapulco. 
Olive brown, abruptly paler olive below middle of 
side. Dorsal with a black edge, which shades toward 
olive at base of fin; anal similar, paler. Pectoral uni- 
formly dusky, the base paler. Teeth 2-rowed above and 
below, canines small. Pectoral 22 in head; snout 5%; 
eye 1% in snout; gape 2? in head; head and body 1% 
in the long tail.
