from the tip of the snout. Mouth medium, curved forwards, with three 

 papillte on its tioor — middle one bifurcate at its tip. 



Entire length, 12i inches; snout to hinder edge of vent, 7; snout to 

 mouth, l-]^o ; snout to end of ventrals, 8; width, 7-i%. 



Color, apparently uniform light reddish brown or olive. The shape 

 of this specimen resembles that of Dasyhatus pastinaca. The species is 

 near U. cruciatus, which is broader than long, and of which the snout 

 does not project. 



No. 7058. Oif east coast Mphon. 



Anotlier specimen, -26543, also from Japan, has a total length of 5f 

 inches, snout to vent 2| and to end of ventrals 3J, and a width of disk 

 of3|. 



This aj)pears to be the young of 7058. There are differences: the 

 snout is not prominent; the disk is wider in proportion to its length, 

 more broadly rounded, and retains its greater width i:>osteriorly ; and 

 the color is darker. The larger specimen, however, is faded, and the 

 other differences are such as age renders less patent. 



Narcine timlei, Bl. Scliij. ; Henle. 



Very young specimen. Vent in the middle of the total length. In- 

 sertion of dorsal slightly behind the bases of the ventrals. Caudal with 

 a blunt angle opposite the end of the vertebral column. 



Light brown, thickly freckled with darker. Large blotches of darker 

 between eye and lateral margin, between shoulder and lateral margin, 

 and between the spiracles; there is one near the pelvis on each side of 

 the dorsal median line, and one between each of these and the lateral 

 margin. There is also a spot on each side of the base of each of the 

 dorsals and one on the base of the tail. The upper portions of the fins 

 are darker. 



No. 20545. Hong-Kong, China. 



Raja fusca, sp. n. 



Specimens taken from the egg-case. Disk three-fourths as long as 

 wide. Snout moderately prominent. General outline similar to that of 

 R. ocellata. Tail from vent equals the length of the disk including the 

 ventrals, depressed, rather broad at the dorsals, behind which it ex- 

 tends in a long point that probably is much reduced in comparative 

 length in the adult. Teeth in thirty series. Eyes moderate, interorbi- 

 tal space nearly half their distance from the end of the snout. Mouth 

 broad, with a slight forward curve. A pair of large spines in front of 

 each eye ; a single spine above each s])iracle ; one behind the head on 

 the anterior end of the vertebral column, sometimes a second behind 

 this on the shoulder girdle, and a median row on the tail beginning be- 

 hind the vent, and reaching the second dorsal. Dorsals separated by 

 two spines. Excepting these spines, the back is smooth. 



Light reddish brown. A black ring about half as wide as the mouth 

 incloses a lighter colored space near the shoulder girdle on each pec- 

 toral.
