Study Material. Male, 383 mm long, with very small claspers; male (type), 517 mm 

 to upper origin of caudal, with well developed claspers; female, about 690 mm to upper 

 origin of caudal (the posterior part of the caudal with its filament has been lost), all 

 from Matanzas Bay, Cuba, now in Harvard Museum of Comparative Zoology. 



Distinctive Characters. The only North Atlantic fishes with which C. cubana might 

 be confused would be one of the other short-nosed chimaerids, i. e. C. monstrosa, Hydro- 

 lagus affinis, H. alberti or H. mirabilis. It is sharply marked off from the last three of 

 these by the presence of a separate anal fin, distinct though small. In general appearance 

 it resembles C. monstrosa closely, but it is separable from monstrosa by the facts that 

 the upper side of its caudal fin is only about half as high as the posterior part of the 

 second dorsal fin above the fleshy base, that the cranial mucous canal on each side of 

 the head meets the aural canal at an acute angle (at about a right angle in C. monstrosa), 

 that the rayed portion of the upper side of its caudal is only about as long as the 

 distance from tip of snout to middle of eye (about as long as from tip of snout to rear 

 of eye in C. monstrosa), and that the tip of its anal fin falls considerably short of the 

 rear end of its second dorsal (anal extends as far as rear end of second dorsal in C, 

 monstrosa). 



Description. Proportional dimensions in per cent of distance between snout and 

 origin of upper caudal fin. Male, 517 mm, the type, and female, 690 mm to origin 



(p. 533), while reports of C. monstrosa from the fishing banks off New England and Nova Scotia seem actually to have 

 been based upon Hydrolagus affinis (p. 539). The South African Chimaera was given a separate name, 'vaillanti, 

 without description, by Dean (Chimaeroid Fishes, Publ. Carneg. Instn., 32, 1906: 7). But examination of the type 

 specimen in the Paris Museum showed nothing to separate it from the northern C. monstrosa (see Barnard, Ann. 

 S. Afr. Mus., 21 [i], 1925: 95).
