Not Carcharias (Prionodon) lamia Putnam, Bull. Essex Inst., 6, 1874: 72 (this was a Carcharodofi). 



Not Prionodon lamia Goode and Bean, Bull. Essex Inst., 11, 1879: 30 (the specimen of Carcharodon reported 



by Putnam, 1874). 

 Not Eulamia lamia Jordan and Gilbert, Bull. U.S. nat. Mus., 16, 1883: 60 (descr. of San Diego, Calif., 



spec, actually tomidla, Jordan and Gilbert, 1882). 

 Not Carcharias lamia Jordan, Proc. U.S. nat. Mus., 7, 1884: 104 (almost certainly refers to leucas; see 



p. 344). 

 Not Carcharhinus lamia Jordan and Evermann, Bull. U.S. nat. Mus., 47 (4), 1900: pi. 5, fig. 17 (embryo, 



evidently of leucas, see p. 344). 

 Not Carcharias lamia Lahille, An. Mus. nac. B. Aires, 34, 1928: 305 (appears to be remotus, see p. 403). 



Carcharhinus macuUfinnis (Poey), 1865 



Large Black-tipped Shark 



Figures 66., 61 



Study Material. Female, about 6 feet 6 inches (1,975 mm.) long, from Salerno, 

 Florida (Harv. Mus. Comp. Zool., No. 35772) and jaws of two males, about 6 feet 

 4 inches (1,915 mm.) long, from Englewood, Florida (U.S. Nat. Mus., No. 109957, 

 I 10306). 



Distinctive Characters. Among the smooth-backed Carcharhinus of the Atlantic, 

 maculipinnis is most like limbatus in general appearance, fins, teeth and color. But it is 

 separated from limbatus by its noticeably smaller eyes, its relatively longer upper labial 

 furrows and gill openings, the noticeably more slender free rear tip of its second dorsal and 

 the perfectly smooth edges of its lower teeth (finely serrate in limbatus^. Also, its first 

 dorsal usually originates somewhat farther rearward, although there may be some varia- 

 tion in this respect. Its dermal denticles are distinctive, also (cf. Fig. 66 A with 62 D).
