cros.s-articulation, which are only evident under considerable magnifi- 

 cation; the posterior 20 are raj^s. Base of first dorsal spine directly 

 above gill slit. The dorsal of the male is a little higher than that of 

 the female. In the male the longest dorsal rays are contained 1| to 

 li in head; in the female If to 1^. Caudal in the female truncate or 

 very slightly rounded; in the male the upper and lower rays produced 

 and filamentous. Pectoral rounded, its length half as long as the space 

 between its base and front of anal. Ventral with 2 rays; the inner 

 ray the longer, reaching f of distance from its base to vent. 



Color light gray; the sides crossed with many dark bands a little 

 wider than the spaces between them, and with edges blended to the 

 lighter color. Posteriorly the bands slope downward and forward; 

 anteriorly, downward and backward; at a little behind the middle of 

 the body the 2 sorts of bands are separated by a V-shaped mark. A 

 conspicuous dark spot just behind eye. Dorsal of female without 

 color, or light and crossed with indistinct dusky wavy lines. Dorsal 

 of male dark, nearly black, and with a black spot across the middle of 

 the eighth to the tenth or eleventh rays from the posterior end. Anal 

 dusky, growing darker toward tips of rays; darker in males than in 

 females. 



This species difl'ers from other members of its genus in the pattern 

 of its color markings. 



Numerous specimens were taken at Tanegashima, in length from 40 

 to TO mm. 



The type is 64 mm. in length and is numbered 53275 U.S.N.M. 

 Cotypes are No. 9364 Stanford University. 



This species belongs to the subgenus Aspidotitus, distinguished from 

 typical Petroscirtes^ by the low anterior spines of the dorsal. In the 

 type of Petroscirtes these are much elevated. 



NOTE ON ANARHICHAS FASCIATUS BLEEKER. 



The wolf fish mentioned by Jordan and Sn3^dier" from Mombetsu, in 

 Iburi, Japan, as Anarhichas species, is doubtless the species described 

 from China as Anarrhichas fasciatus.^
