 Manta pinchoti Whitley, op. cit., p. 182 (type locality: Marquesas Islands) 



(on Manta birostris Fowler, 1932). 

 Mania foivleri Whitley, op. cit., p. 182 (type locality: Fanning Islands) (on 



Manta hirosiris Fovpler, 1927). 

 Manta pakoka Whitley, op. cit., p. 183 (type locality: Uaar Hat Island. Teuaua, 



Ua Huka, Marquesas Islands) (on Pakoka Pinchot, To the South Seas, pp. 



406, 408, 421, fig., 1930). 



Head width 3% in total length; head length to first gill opening 

 3% in its own width. Snout very broad, as seen above with broadly 

 concave profile; eye lateral, equally visible above and below, about 

 14 across interorbital ; mouth width 2% in disk length, or 6% in 

 greatest disk width; dental plate below with 143 teeth in transverse 

 series ; interorbital widely depressed, slopes convexly down each side. 

 First pair of gill openings ll^ in interspace, likewise smaller last pair. 



Skin with rough asperities, each of larger with radiated bases. 



Triangular dorsal fin over ventrals, with hind truncate edge ending 

 little before hind ventral edges, fin length 51/5 in disk length to mid- 

 dle of front snout edge ; tail slightly longer than disk length, without 

 spine; disk length 2% in disk width, widest midway in its length, 

 outer angles narrowly triangular and curved backwards, front edges 

 little convex and hind edges concave; ventral ends extend little be- 

 yond hind pectoral edges, obtuse. 



Above blackish or dark olive, below whitish. Length, 1773 mm. 

 (Hilgendorf.) 



Eed Sea, Natal, South Africa, India, Malay Peninsula, East Indies, 

 New South Wales, Melanesia, Polynesia, Hawaii. I have long thought 

 the Polynesian and Hawaiian specimens with 150 teeth in the dental 

 plate were the Atlantic Manta hirostris Walbaum. Hilgendorf's fig- 

 ure of a Red Sea specimen, however, shows only 143 teeth and Barnard 

 mentions a South African specimen with 230. Garman maintains 

 the Atlantic species with the dental plate extending over the whole 

 width of the lower jaw bearing about 100 separated rows of teeth, at 

 least in the young. 



The following is Macleay's account of Ceratoptera alfredi Krefft: 



"This is the name affixed to a stuffed specimen of this genus of 

 enormous size, in the Australian Museum. It was captured at Manly
