Color dark brown, everywhere with roundish white spots, 

 most of them one-eighth of an incii in diameter, equal to or 

 exceeding the pupil; these spots coalesce on the ventral 

 surface, forming vermicular markings, which usually are 

 wider than the brown interspaces; the dorsal dots are nar- 

 rower than the brown ground between. All the fins simi- 

 larly spotted, though the spots are smaller than on the body. 

 No streaks nor black marks anywhere. Pectoral and dorsal 

 fins with a white edge as wide as the dorsal spots. Anal fin 

 very narrowly margined with white. 



This description is made from a dried skin in fine condi- 

 tion which came from Mexico. The specimen is now in the 

 collection of the California Academy of Sciences, and bears 

 the registered number 2,996.
