DiVrema atripes Jordan & Gilbert, Proc. U. S. N. M. 1880, 320 (California) ; Jordan & Gilbert, 
Proc. U. S. N. M. 1880, 456 (Monterey Bay, California); Jordan & Jouy, Proc. U. S. N. 
M. 1881, 11 (Monterey, California); Jordan & Gilbert, Proc. U. S. N. M. 1881, 50 (Mon- 
terey Bay, California); Jordan & Gilbert, Syn. Fish N. Am., 595, 1883 (Monterey Bay);

Phanerodon atripes Eigenmann & Eigenmann, N. Y. Acad. -Sci., vi, June, 1892 (Cortes Banks, 
Monterey). 
fDitrema orthonotus E. & E., West Am. Scientist, Oct., 1889, 127 (Cortes Banks) 
Habitat: Monterey to Cortes Banks. 
This species has so far been taken at only two localities. D. orthonotus will prob- 
ably prove identical with atripes. At the time orthonotus was described atripes had 
not been found within 400 miles of the locality of orthonotus.

Dorsal fin, vxn, 15, the sixth or seventh spine highest; body elongate, regularly elliptical. Color
