Described from the type. No. 6457, Carnegie Museum Catalog of Fishes, a 

 female 92 mm. in total length, and a female cotype, 83 mm. long, both from Yoko- 

 hama Market, doubtless from outside the heads of Awa and Boshu. The measure- 

 ments are given in hundredths of body-length to base of caudal, those of the cotype 

 in parenthesis. 



Length of head .245 (.235); depth .25; width of head .20; eye .05; snout 

 .75; maxillary .07 (.08); longitudinal diameter of disk .10; distance snout to 

 disk .15 (.13); disk to vent .18 (.14); snout to vent .40 (.35); depth of caudal 

 peduncle .04; length of upper pectoral lobe .16; of lower pectoral lobe .125; gill- 

 slit .07; interocular space .075; distance vent to insertion of anal .135; snout to 

 dorsal .30; D. 37; A. 30; C. 14; P. 33. 



Body deep, not quite as wide as deep at opercle; tail strongly compressed; 

 mouth nearly transverse; tip of maxillary not reaching eye; snout slightly over- 

 hanging premaxillaries, rounded in profile; nostrils tubular, without flap, situated 

 at level of pupil; teeth simple, in broad bands, blunt. Gill-opening not extending 

 below first pectoral ray, set somewhat obliquely. 



Dorsal not notched, first rays low, increasing in height until middle of fin; anal 

 similar; dorsal and anal joined to caudal by its basal third, last rays not shortened 

 in either; pectoral notch shallow, lower lobe extending just beyond posterior margin 

 of disk, its rays but half an eye-diameter longer than those of notch. 



Color in alcohol reddish; distal half of pectoral dusky; dorsal and anal some- 

 what darker than pectoral, anal much more deeply colored than dorsal ; caudal dusky, 

 peritoneum colorless, as is buccal cavity.
