Family OPHICHTHYIDyE. 



34. Myrichthys tigrinus Girard. Culevra. 



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 Myrich- 

 thys tyrinus were said to come from Adair Bay in Oregon. 

 It has, however, not yet been taken north of the Gulf of 

 California, 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.) ( Ophisurus calif or- 

 niensis Garrett; Herpetoichthys callisoma Abbott.) 



Recorded by Gilbert from Mazatlan; not seen by us. 

 A specimen certainly belonging to this species has 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 of 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 2f in head: snout $% ; 

 eye ljA, in snout; gape 2'i in head: head and body 1^3 

 in the long tail.
