is rather low, and points straight backward. On its anterior end, 

 close together, are two tubercles above the front of the lower eye; 

 on the posterior margin of the upper orbit are two blunter, less con- 

 spicuous ones; a very small one is on the anterior margin of the 

 upper eye. The eyes are large and protruding, and the upper one is 

 posterior to the lower. The left nostrils are remote from the base 

 of the dorsal fin, but nearer to it than to the ri^ht nostrils. The 

 maxillary reaches nearly to the anterior margin of the pupil. There 

 is one row of very minute teeth on the eyed side of the lower jaw, and 

 closely set, small hands on the blind side of both jaws, hut none on 

 t he premaxillary of the eyed side. 



The dorsal I'm springs from, or slightly above, the level of the tip 

 of the snout, with live or six rays on the blind side. The anal and 

 dorsal are equal in height, the longest ray is contained seven times 

 in the length of the body. The ventral of the eyed side is much 

 posterior to that of the blind, and at a considerable distance from the 

 ventral body ridge; 



The scales are small and imbricated over the whole body, or at 

 least in contact with each other. The lateral line has a dorsal branch 

 running back from the head to about the thirty-fifth dorsal ray. and 

 a short anterior branch is usually present. 



The color in alcohol is uniform light brown on the eyed side, with 

 a very prominent dark brown spot ocellated with milk white at the 

 middle of the lateral line. A very inconspicuous, similar spol is at 

 the base of the dorsal and anal fins posteriorly. Spots of white of 

 irregular size, but very indefinite, are scattered over the body, 

 especially along the bases of the vertical fins. 



Here described from nine specimens from Albatross stations 3027 

 and 3024, in the Gulf of California. The type is from the latter 

 station, and is 6 inches in length. It is deposited in theU. S. National 

 Museum. Cotypes from the same locality in the National Museum 

 have been examined (Hi specimens examined altogether). Other 

 cotypes are deposited in the collections of Stanford University.
