NO. 1324. ELASMOBRANCHIATE FISHES— JORDAN AND FOWLER. fi53 



Interorbital space li in snout; width of mouth If: lenj^-th of first 

 dorsal, a little more than i; caudal !^f ; oye 8^ in interoi-bital space. 



Body rhomboid, very broad, width of the disk much greater than 

 its length. Head small; snout very little produced, though ending in 

 a small point; anterior margin of disk full, slightly undulated, and 

 eyes nearer to it than their space between; mouth large, slightly 

 unduhite; teeth in about 45 rows in upper jaw, small, I'ounded; nos- 

 trils very large, broadly separated, hut not eipial to width of mouth 

 at its corners, with which it is also confluent; nasal Haps lai-ge. post(»- 

 rior margin fringed; length of nostril to corner of mouth e((ual to two 

 and one-half in space between lattei- and tip of snout; interorbital 

 space concave, though flattened in middle, and supraorbital ridges 

 little elevated. Spiracles rather large, a little smaller than e^^e, 

 oblique, directly posterior. Gill openings very small. 



Bod}^ almost perfectl}^ smooth, with exception of some roughness 

 on snout, several small tubercles on supraoral ridges, one in center of 

 back in front, and 5 irregular rows of thorns on back of tail. 



Dorsals separated, distance between al)()ut one-sixth base of lirst; 

 second dorsal confluent with small caudal, only sepai-ation a deep 

 notch, and equal to first dorsal in size; angle of pectoral would fall at 

 about middle of length of disk; ventrals moderate. 



Color in spirits, brown al)ove, whitish beneath; upper surface 

 marked with small, ])lackish spots; at bases of pectorals, two large, 

 blackish rings above, ])elow which, though fai'ther apart, also two 

 indistinct, imperfect rings, and still posterior on last rays, a small, 

 black spot; nine indistinct, blackish cross-bands on upper surface of 

 tail; lower surface of body whitish, soiled with l)rown, pores with 

 grayish borders. 



Length 17i inches. 



Coasts of Japan, rather common. We have specimens from ]\risaki, 

 Tokyo, Wakanoura, Kobe, Tsuruga, and Nagasaki. As this species 

 is mature at about the length of the specimen described, the rays "de 

 taille enorme" noticed by Schlegel must l)elong to Raja tengaov some 

 other species. In our young specimens the spots on the back form 

 more or less distinct ocelli, and the mottlings above are distinct, fre- 

 quently with a number of light spots. The lower surface is white, 

 but the outer third of the pectorals broadly borden^l with pale ))rown, 

 which in the adult is paler. 



{I'eno-ei, the Japanese name.) 



less than their distance from tip of snout; snout somewhat rounded; mouth with 40 

 rows of teeth; interorbital space concave. A few small tubercles about eyes; rest of 

 body smooth, except for a large tubercle behind eye and a row of larger or smaller 

 ones along middle of back. Color dark brown, with larger and smaller yrll.iwish 

 spots. Described from a specimen 2.^ cm. long, taken at Nagasaki."
