parallel well-spaced lateral lines. On head row of large scales close 
above and along upper edge of maxillary, besides vertical row on pre- 
opercle flange. Maxillary and side of mandible very minutely scaled. 
Belly and sides of abdomen naked and on breast four close-set finely 
scaly areas. Of fins only caudal basally covered with small scales. 
D. IV—I, 20, 1, second spine 31% in total head length, second ray 
2; A. 1, 17,1, spine 414, second ray 224; least depth of caudal peduncle 
514; caudal 114, deeply forked, lobes sharply pointed; pectoral 24, 
rays 12; ventral rays I, 5, fin 114, reaches 1% to anal. 
Color in alcohol brown above, paler to whitish below. Fins all 
pale or uniform brownish. 
Apparently very closely related to Champsodon arafurensis 
Regan,” though that species would differ at once in having the 
“ventrals a little shorter than the head, extending to the origin of 
the anal,” in specimens 50 to 75 mm. long. In all my specimens the 
ventrals fall well short of the anal in the larger ones and not even 
reaching opposite to them in the smallest. Regan has stated his 
Champsodon arafurensis “seems to be nearest to the one figured by 
Alcock 1* and may be the same.” Tf this is true Alcock’s figure would 
further differ from my material in showing the posterior end or 
tip of the preopercular spine falling well forward of the origin of 
the ventral fin. In all my specimens it distinctly extends until op- 
posite it.
