riorly (toward the base of the clasper), but these 

 denticles are on the side of the rhipidion adjacent 

 to the main axis of the. shark and in quite a dif- 

 ferent poistion than the hooks of the claspers of S. 

 torazame. 



The claspers of S. torn i are quite small and 

 simple structures as compared with the claspers of 

 Galeus area. The claspers of an adult male 

 Galeus arae 275 mm. long are obviously more than 

 10 times the weight or volume of the claspers of 

 an adult male Scyliorhinus torrei 272 mm. long 

 and are considerably more complicated. 



The stomach on one .6'. torrei contained cepha- 

 lopod remains (beaks) including a cartilaginous 

 eye capsule {Sepia?) 12 mm. in minimum diam- 

 eter. Also present, were several fish scales 4 to 

 7 mm. in breadth. 



In addition to specimens for which measure- 

 ments are summarized in table 4 (M/V Silver Bay 

 stations 2457 and 3474 in Santaren Channel), 

 specimens have been seen from M/V Silver Bay 

 stations 2475 and 2477 in Santaren Channel; from 

 M/V Oregon stations 1340 and 1343, also in the 

 Santaren Channel; from M/V Oregon stations 

 2482, 3474, and 3512, northward from the San- 

 taren Channel to the offing of Jupiter, Florida; 

 and from M/V Orego-n station 2650, near the 

 Virgin Islands. Previously recorded specimens 

 were, from the north coast of Cuba (Bigelow and 

 Schroeder. 1948). All recorded captures were 

 from 366 to 550 m. except the one near the Virgin 

 Islands which was in 229 m. 



The teeth in the specimens at hand are in 21 + 

 21/20 + 2 + 20 to 23 + 23/21 + 1 + 21 rows. The 

 tooth shape is similar to that of other Atlantic 

 species of Scyliorhinus. In the specimens ex- 

 amined, the cusps of the extreme lateral teeth of 

 the lower jaw are variably reduced, in some al- 

 most absent.

Diagnosis. — S. meadi differs from other species 

 of the genus Scyliorhinus in color pattern. The 

 upper parts are light gray in fresh specimens 

 (brownish in specimens preserved in alcohol) 

 with seven quite distinct darker rectangular 

 blotches or saddles extending across the middorsal 

 area, the first anterior to the pectorals, the second 

 and largest (in specimens of the type series) at the 

 level of the pectoral tips, the third anterior to the 

 pelvic origin, the fourth through the first dorsal 

 fin, the fifth through the second dorsal fin, the 

 sixth at the base of the caudal fin, and the seventh 

 across the caudal fin, anterior to the notch. In 

 additional to the dorsal saddles, a series of lateral 

 blotches of color alternate in more or less checker- 

 board fashion with the first three or four dorsal 

 saddles, some of these extending indistinctly to the 

 upper surfaces of the pectoral and pelvic fins. 

 Traces of additional dorsal blotdies are present 

 between some of the principal dorsal saddles in 

 some of the specimens. Lighter colored areas are 

 included in some of the blotches, but these are 

 indistinct and larger than the eye. 



Two species of Scyliorhinus, torrei and retifer, 

 are present in the same geographical area as 

 meadi, but the color patterns of these are so strik- 

 ingly different from that of meadi that there 

 should not be any possibility for confusing them. 

 No intergrades have been observed. 



S. meadi appears to be closest in appearance to 

 S. hesperius which is described in the following' 

 pages. Differences in color pattern between the 

 two are constant in the material examined. 



S. meadi also differs from other American 

 members of Scyliorhinus in having the typical 

 dermal denticles of dorsolateral surfaces some- 

 what larger in comparison with specimens of 

 equal size, somewhat more erect, somewhat nar- 

 rower, and somewhat more widely spaced. These 

 differences are all a matter of degree and are not 

 necessarily apparent unless specimens of similar 

 size are compared. The differences do, in com- 

 bination, give S. meadi a more shajr.oy appearance 

 than any of the other American representatives 

 of the genus.
