Disk rhomboid, broader than long, very blunt-angled in front, outer and 

 hinder margins and angles broadly rounded, anterior margins scarcely indented 

 opposite the spiracles. Snout short, about one and one half times the width of 

 the mouth, tip produced, rounded. Mouth large, undulated, width two thirds 

 of the length of the snout. Teeth small in 50 (42-50) rows, the crowns in a low 

 rounded keel ending in a sharp corner on the inward edge. Eyes and spiracles 

 rather small, their combined lengths nearly half the snout, or little more than 

 the interorbital width. Tail strong, short, less than length of body. Dorsals 

 separated by a space with tubercles. Body nearly naked, a few minute spines 

 along the anterior margins near the outer angles and below the edge of the snout. 

 Tubercles small, compressed, hooked: a pair of very small ones in front of each 

 orbit, a larger one opposite its middle and another behind it, two median tuber- 

 cles behind the head in front of the shoulder girdle, and a median and four (2-4) 

 lateral rows on the tail. 



Rusty brown profusely sprinkled with small spots of brown, in cases forming 

 rings or vermiculations, uniting in a large rounded inclosure on each shoulder, 

 behind which one or two smaller rings frequently occur. Lower surfaces ding}' 

 white, brownish near the outer margins; pore openings below snout and gills 

 dark. 



Specimen described from the Idzu Sea, Japan, Alan Owston. Total length 

 175, snout to the abdominal pores 9, snout to mouth 2l, and greatest width 12 

 inches.
