111 18U5 the junior author served as naturalist on the U. S. 

 Fish Conimission steamer Albatross and obtained many fishes at 

 various depths. Among them were 14 species apparently hith- 

 erto undescribed. Diagnoses of these are here given by permis- 

 sion of Captain John J. Brice, U. S. Commissioner of Fish and 

 Fisheries, and will hereafter be described at length and illus- 

 trated. 



RAIID.E. 



Raia rosispinis. 



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

 tilatre and a blunt tip. Interorbital 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 ai'e interspersed between the disk and 

 the pectoral rays. A row of about 26 thorn-like spines, with radiating 

 ridges, extends from the interhumeral area to the dorsal fins ; two spines 

 on each shoulder. One spine above antocular region, another above post- 

 ocular region, and another behind it about half the distance. 



Raia obtusa. 



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 commencing at the inter- 

 humeral area ; a row of scarcely enlarged acute spines above the eye ; an 

 uninterrupted row of unguiform spines with smoth bases extending from 

 the interhumeral area to dorsal fin; two similar spines arm each shoulder.
