Range. Occurs everywhere in tropical parts of both the Atlantic 

 and the Pacific; Revillagigedo and Galapagos islands. 



We have i specimen, 280 mm. long, taken from the stomach of 

 a shark ( Carcharias platyrhynchus) caught in Tagus Cove, Albe- 

 marle Island. The color is entirely gone, but in other respects the 

 specimen differs in no way from a specimen of D. hystrix in the 

 Stanford University collection.

Range. Japan, Hawaiian Islands, Galapagos Islands, coast of 

 southern California. 



One specimen found dead and floating on the surface of the water 

 in Tagus Cove, Albemarle, probably killed by dynamite we had ex- 

 ploded in the neighborhood. The species has been reported from 

 San Pedro, California, and in the Stanford University collection are 

 specimens from Japan and Honolulu. 



General color brown, paler below ; fins all closely spotted with 

 small round black spots, each smaller than the pupil ; sides of body 

 and forehead spotted with larger black spots ; in front of pectoral a 

 dusky vertical band, another running downward from in front of eye 

 to ventral side of head just back of symphysis of lower jaw where 

 those of the 2 sides are confluent; dark area behind pectoral. The 

 Japanese specimen has the same black bands, post-pectoral black area, 

 and fin spots as the Galapagos specimen, but there are no spots on 

 the body.
