Five new species of gobies obtained in the course of several expedi- 

 tions made by Captain G. Allan Hancock, to the Gulf of California 

 in 1936 and 1937, and to the Secas Islands, off Panama, incidental to 

 an investigation of the Galapagos Islands in 1935, are here described. 

 In addition I take this opportunity to offer brief diagnoses of three 

 other new species from the Gulf of California, discovered by me in an 

 extensive investigation of American gobies. They will be treated more 

 fully in a future paper which will contain revisions of their respective 

 genera. One new genus and one new subgenus, based on two of the 

 species, are established. 



All proportional measurements stated below refer to percentages 

 in the standard length. The given length of specimens refers to the total 

 length, including the caudal fin, unless otherwise specified. 



Ghriolepis zebra, new species 



Description. — Form elongate, body compressed, head strongly de- 

 pressed. Snout notably blunt when viewed from dorsal aspect. Mouth

 jaw projecting. Maxillary short, its end falling under anterior margin 

 of pupil. Interorbital of medium width. Tongue very moderately emargi- 

 nate. Teeth in outer and inner rows in both jaws strongly enlarged; 

 one or two irregular rows of much smaller teeth in between at symphy- 

 sis, one row posteriorly; in lower jaw outer row confined to front, 

 the teeth subequal, inner row extending about half the distance from 

 symphysis to angle of mouth, the last two teeth larger than others, 

 caninoid, the small teeth continued posteriorly in a single row to angle 

 of mouth; in upper jaw outer row extending nearly to angle of mouth, 

 the posteriormost three or four teeth somewhat smaller, the others sub- 

 equal, inner enlarged teeth confined to front. No spine at angle of pre-
