104(a). RAJA KOSISPINIS, Gill & Townsend. 



Snout moderately produced, with a soft, moderately narrow, rostral car- 

 tilage and a bluutish tip; iuterorbital space nearly plane; snout with a 

 number of plates having stellate bases about middle, and many smaller 

 asperities, leaving only the borders of the pectorals and ventrals naked; 

 larger spines with stellate bases are interspersed between the disk and the 

 pectoral rays; back with sparse, coarse prickles; a row of about 26 thorn- 

 like spines, with radiating ridges, extends from the interhumeral area to 

 the dorsal fins; 2 spines on each shoulder, 1 spine above autocular region, 

 another above postocular region, and another behind it about the dis- 

 tance; skeleton soft. Bering Sea; only the type known, (roseus, rosy; 

 spinns, spine.) 



Raia rotispinis, GILL & TOWNSEND, Proc. Biol. Soc. Wash., xr, 1897 (Sept. 17, 1897), 231, 

 Bering Sea. (Type, No. 48762, TJ. S. Nat. Mus. Coll. Albatross.) 



Raia obtusa* GILL & TOWNSEND, Proc. Biol. Soc. Wash., xi, 1897 (Sept. 17, 1897), 231, 

 Bering Sea. (Type, No. 487G3, TJ. S. Nat. Mus. Coll. Albatross.) 



104 (b). RAJA INTERRTJPTA, Gill & Townsend. 



Snout moderately produced, with a very soft attenuated rostral carti- 

 lage and a blunt tip; interorbital space concave ; mouth small; the width 

 equal to ^ preoral area; entire back covered with very small embedded 

 spines, extending nearly uniformly over the disk and snout, leaving only 

 the tip of the latter naked; a row of compressed, acutely curved, smooth 

 spines along middle of back, extending from the interhumeral region to 

 dorsal, but interrupted along the posterior half of disk, where the spines 

 are absent or obsolete; about 4 spines are in the anterior portion and the 

 series recommences on a line with the emargination of the disk; a single 

 spine on each shoulder and occasionally a rudimentary second ; no special- 

 ized supraorbital spines. Bering Sea; only the type known, (interrup- 

 tu8, interrupted.) 



Raia interrupta, GILL & TOWNSEND, Proc. Biol. Soc. Wash., xi, 1897 (Sept. 17, 1897), 232, 

 Bering Sea. (Type, No. 48760, U. S. Nat. Mus. Coll. Albatross.) 



Page 75. Raja aleutica and Raja abyssicola were described by Gilbert 

 (not Gilbert & Thoburn) in Kept. U. S. Fish. Comm. 1893 (Dec. 9, 1896), 396 

 and 397, pis. 20 and 21. 



* The following is the original description of this nominal species: 

 Snout not at all produced, but very bluntly rounded ; interorbital space narrow; mouth 

 small, rectilinear; minute distant prickles on the snout, the anterior portion of disk and 

 interorbital area, as well as in a broad median band extending on tail to dorsal and com- 

 mencing at the interhumeral area; a row of scarcely enlarged acute spines above the eye; 

 an uninterrupted row of unguiform spines with smooth bases extending from the inter- 

 humeral area tc dorsal fin ; 2 similar spines arm each shoulder. Bering Sea; only the type 

 known. ((Jill and Townsend.) To which we add: Spines in longitudinal series 23 to 25; 

 width of mouth Ig in preoral area; width of disk li times its length; tail a little longer 

 than disk; interorbital width 3 in snout; snout from eye 3g in disk to end of base of ven- 

 ' trals. Color plain brown, rather pale. One specimen il inches long, a very young male 

 in very bad condition. Evidently the young of R. rosispinis.
