Careproctus sinensis Gilbert and Burke 1912&, p. 371. 



Type.— 'No. 73339, U.S.N.M.; Albatross Station 4813, off Sado 

 Island, Japan Sea; depth 200 fathoms. Length 72 mm. 



Distribution. — Japan Sea, off Sado Island, Albatross Station 4813;. 

 depth 200 fathoms. See remarks. Three specimens examined. 



Relationships. — C. sinensis resembles C. segaliensis in many respects. 

 It can be distinguished from the latter species by the larger number of 

 pectoral rays, larger disk, and minor differences.

suprabranchial pore; man- 

 dibular pores enlarged, the anterior pair united. Anterior dorsal 

 rays shortened, increasing rapidly in length. Disk normal, flat, 3.5 

 in head. Lower lobe of pectoral short, 2.3 in the head, reaching 

 sUghtly past vent. Vent close to disk. Color pale. Our largest spe- 

 cimen 72 mm. in length. 



RemarTcs. — Specimens No. 53811 and No. 53812, from Albatross 

 Stations 2847 and 2851 , south of the Alaska Peninsula, differ from the 

 type in several respects. These specimens are in poor condition and 

 probably represent a new species. Body outline not abruptly descend- 

 ing above pectoral, the dorsal outline gradual. Occiput not swollen. 

 Eye small, the lower half silvery. Pyloric coeca 25. Anterior dorsal 

 rays increasing gradually in length. Lower lobe of pectoral not reach- 

 ing vent. Vent back of disk by diameter of disk. Two suprabranchial 

 pores present, small.
