A NEW DEEP-SEA FISH FROM THE PHILIPPINES—-MILLER 89 
U.S.N.M. No. 185935, 225 mm. in standard length, has a fully devel- 
oped right eye but the left eye is atrophied. The left orbit is developed 
but is completely closed over by skin and scales to form a concave 
pocket through which no part of the eye is visible. Otherwise, this 
fish appears to be perfectly normal. 
Range.—The new genus is so far known only from the material listed 
herein (see sections on “Holotype” and “Paratypes”), all of which 
came from various islands in the Philippines. 
Etymology.—tThe specific name arenidens, meaning “sand tooth,” 
refers to the sandpaperlike dentition. Solivomer refers to the single 
patch of vomerine teeth. 
Acknowledgments.—In working out certain osteological charac- 
ters of Solivomer I received the generous assistance of Dr. Leonard P. 
Schultz. Dr. Carl L. Hubbs kindly suggested the generic and specific 
names,
