5. Raja stellulata Jordan and Gilbert. 



A single specimen twenty-one inches in entire length was dredged 

 in thirty fathoms of water. Comparing this with specimens of similar 

 size from the coasts of California, Oregon, and Alaska, the following 

 differences appear: the prickles are sparser and finer; the snout is 

 not nearly so acute; the claspers are slenderer, and very flexible, 

 being quite inflexible in the others; the teeth are not so sharp, and the 

 markings are different. In view of the scanty material at hand, 

 none of the differences are great enough to warrant considering this 

 form a separate species. 



Most of the markings remain distinct in alcohol. The color is 

 prevalently dusky light brown with indefinite, very faint slaty spots 

 of varying size scattered over the body, the one at the base of the 

 pectorals being the largest. Small dark spots, some of them arranged 

 around the slaty spots, but not numerous enough to suggest rings, 

 are scattered over the body. The most conspicuous markings are 

 clear naples-yellow spots, ringed with dusky brown, and arranged 

 symmetrically in reference to opposite sides of the upper surface 

 of the disk. The largest is triangular with rounded angles, placed 

 behind the middle of the pectorals, and probably composed of three 

 round spots fused together. A small round spot just inward from this 

 one outward from the eye; one behind the gill-cavity on the shoulder- 

 girdle; one on the middle of the ventral; four or five following the pos- 

 terior edge of the pectoral; and a few others less definite scattered
