101. RAJA RHINA, Jordan & Gilbert. 



Disk broad, the outer pectoral angle sharp, farther forward than in R. 

 Unoculata. Anterior outline of pectoral somewhat undulated and exceed- 

 ingly concave, so that the snout is very long, acuminate, and tapering to 

 the extreme point ; interorbital space quite narrow, little concave. Supra- 

 ocular ridges slightly elevated ; eyes large, much longer than spiracles. 

 Spines on body comparatively strong; 5 to 7 above the eyes; 2 or 3 near 

 the middle of the back ; none on the median line of the back until oppo- 

 site the posterior end of ventrals, where a series of rather sharp spines 

 begins; prickles on body above rather large, sharp, strongly stellate, 

 those on the snout largest and most stellate; skin above everwhere 

 prickly in the female ; the prickles small and sparse on the base and edges 

 of the pectorals and on ventrals ; larger on the median region of the disk. 

 Male with bases of fins smooth, and the prickles generally fewer and 

 smaller ; anterior edge of pectoral with spines ; under side of disk almost 

 everywhere prickly in the females, smooth posteriorly in the males. 

 Mouth somewhat arched. Teeth f$. Color light brown, nearly plain, 

 with a dark ring at base of pectorals, which grows obscure with age. 

 Disk Vtt broader than long, its breadth twice the length of the tall. 

 Snout nearly i the length of the disk, 3f times the interorbital width. L. 

 2J feet. Monterey to Alaska ; not rare, especially northward, (piv, snout ; 

 rasp.)

(Bio SKATE OF CALIFORNIA.) 



Disk broad, its widest part behind the middle. Snout long, regularly 

 long acuminate, but not very sharp at tip; the anterior outline of the pec- 

 toral not much undulated, and little concave ; interorbital space very 

 broad, almost flat, slightly depressed in the middle ; supraocular ridge 

 scarcely elevated; eyes small, shorter than the spiracles. Spines on body 

 small and few ; 2 or 3 small spines around the eye ; 1 or 2 near the center 

 of the back; otherwise none on median line of back in front of base of 

 ventrals, where a series of spines begins, feeble anteriorly, but growing 

 larger backward; females (as in other species) with lateral series 

 of spines on the tail ; upper surface mostly covered with minute prickles 

 which are largest on the median line of the back, on the tail, and the front 

 of the pectorals. Disk smooth below, except anteriorly. Teeth about f f ; 

 the jaws rather strongly arched. Disk broader than long, its width 

 twice the length of the tail ; snout 31 in length of disk, 2f in interor- 

 bital width. Color brown, with a dark ocellate ring at base of pectorals; 

 upper surface everywhere with round pale spots. The largest of our
