Carcharhinus remotus (Dumeril), 1865 

 Figures 76, 77 



Study Material. Seven specimens from Rio de Janeiro, about 650 to 695 mm. long 

 (Harv. Mus. Comp. Zool., No. 703).'" 



Distinctive Characters. Among the smooth-backed subdivision of the genus, with 

 which it falls, remotus is closest to limbatus and maculifinnis as regards teeth, but it is 

 separated from both of these by its much shorter gill openings (see Key, p. 324), as well 

 as by its lower precaudal pit, which is only faintly indicated, and by its fins which are 

 without conspicuous black markings, at least after preservation.

 C Eleventh upper tooth. D Fourth lower tooth. E Ninth lower tooth. B-E, about 5.2 x. F Left-hand nostril, 

 about 3.2 X.

 from Rio de Janeiro (Harv. Mus. Comp. Zool., No. 703). Female, 693 mm., same local- 

 ity and number. 



147. While provisional acceptance of Carman's (Mem. Harv. Mus. comp. Zool., 36, 1913: 138) reference of these 

 specimens to this species seems justified, the original account of it was so brief that the correctness of this identifi- 

 cation can be tested only by re-examination of the type specimen, novc or formerly in the Paris Museum.
