24 DEEP SEA FISHES. 
Specimen 3357 from deeper water differs in a longer closer pile, in which 
the longitudinal arrangement is less evident, a possible indication of specific 
differences.

Raja borea nom. sp. n. 
This is the species described and figured by Giinther in the Fishes of the 
“ Challenger” Reports, page 8, Plate IV., as Raia hyperborea. There are too 
many points of difference, however, to admit of retention in that species. 
R. borea is somewhat closely allied to R. budia, but is more robust, broader 
on the forehead, less sharp in the angles of the disk, less slender in the tail, 
and less uniform in coloration ; it has a smaller number of tubercles all told, 
but has one directly above each orbit that is not found in the type described 
above. It agrees with &. dadia in the group of tubercles on each shoulder, 
but has a smaller number in the dorsal series. 
Compared with &. hyperborea, R. borea is less angular, shorter in the snout, 
longer in the tail, and has a large tubercle above each eye and another on 
each shoulder between the outer pair and the vertebral series, both of 
which tubercles are lacking on the type of L. hyperborea. The colors of R. 
borea are “ Grayish brown above with a trace of a darker spot on each side 
of the body; lower parts white, with large subsymmetrical brown patches; 
in very young specimens the lower parts are uniform white.” The &. hy- 
perborea of Collett’s figure is uniform dark grayish brown on the back, and 
white beneath with large subsymmetrical markings of brown toward the 
sides and around the edges. The leneths of the types secured by the “ Chal- 
lenger” varied from six and one half to twenty-four and one half inches. 
“ Farde Channel; depth 400 to 608 fathoms.” 
Raja hyperborea Collett, 1878, Forh. Vid. Selsk. Chra., No. 14, p. 7,— 
1880, Nordhavs—Exp., p. 9, Pl. I., figs. 1 and 2. The resemblance between 
this species and R. badia is not very close. R. hyperborea is distinguished 
by greater squareness in outlines as seen from above, including the ventrals 
in the disk, and by a shorter tail, by lack of the inner tubercle of the 
humeral group, by a smaller group of tubercles in the vertebral series, by 
greater uniformity in the spines of the back, and by the color of the ven-
