418.— NOTOGRAMMUS Bean. 
(Bean, Pioc. U. S. Nat. Mus. iv, 147, 1881: typo Sticho'us rothrocici Bean.) 
Tliis genus differs from Sfichceus in the presence of a single lateral 
line along the base*of the dorsal fin. It is known, however, from im- 
mature examples onlJ^ The caudal fiii is emarginate, a character 
unusual iu this family, (voiro?, backj ypaij.fj.ij, line.) 
118<?. N. rotB»a*ock.i Bean. 
Pale brown, with 3 series of paler spots, those of the median series 
usually longer and narrower than the others; a series of about 10 iiale 
spots on median line of back, the anterior as large as eye; a dark 
striiie around snout to end of opercle ; a very narrow dark striiie 
along base of dorsal, its lower margin seeming to mark the course of 
the superior lateral line. Body covered with minute scales; lateral 
line undeveloped (in the immature specimens known), apparently run- 
ning close to outline of back. Teeth in the jaws, and apiiarently on 
vomer and palatines. Gill-membrane deeply cleft, free from the isth- 
mus. Eye 4 in head, as long as the subconical snout; maxillary 
reaching front of i)upil. Dorsal beginning above uiiper axil of pec- 
toral; like the anal, connected by a low membrane with the caudal; 
caudal emarginate behind; veutrals short, close together, 3 in head, 
and not half as long as pectorals; longest dorsal spines half height of 
body. Head 44; depth C. B. C. D. XLVIII; A. I, 34; V. I, 4; P. 15;
