Cetacca. 7127 



" from the high seas," with series of 38 teeth, presented by Mr. C. 

 Hervey (Journal of the Asiatic Society, vol. x. p. 937), and two skulls, 

 toothless, and wanting the lower jaw, with series of 39 tooth-sockets. 

 Length 15 and \b^ inches. Origin unknown, but presented by myself. 

 All of these would appear to be the same, but the left ramus of a lower 

 jaw, with series of 43 teeth, is vertically much deeper at the symphisis, 

 and therefore undoubtedly appertains to a distinct species. 



Also a skull according with Delphinus Eurynome of Gray, and another 

 with D. obscurus of Gray, which, together with the Red Sea example 

 of Steno rostratus, were made over to the Society's Museum from that 

 of the Calcutta Medical College in 1843. Lastly, the skull of a dol- 

 phin affined to D. Delphis of Linneus, and " procured during the 

 voyage from England to India." It was presented by the late Mr. 

 R. W. G. Frith, and is probably an undescribed species. With a 

 general resemblance to that of D. Delphis the intermaxillaries, united 

 as far as the middle of the rostrum, are vaulted, so that the section of 

 the united middle portion forms a complete semi-circle, rising abruptly 

 from their maxillaries, and being there only as broad as the exposed 

 portion of each maxillary ; probably a distinctive specific character. 

 Teeth |-^ — 4^. If confirmed as a new species, I propose calling it 

 Deilephila Frithii.* 



Of the Gangetic susu {Platanista gangetica) we have a stuffed 

 male, presented by M. Alfred Duvaucel, a stuffed female, and also a 

 stuffed example of a young female procured by myself With skulls 

 of adult male and female, the former toothless, and presented by Dr. 

 Wallich. The entire skeleton I have long been trying to obtain. 

 There is a fine series of skeletons of this species in the Museum of 

 the Calcutta Medical College. 



Though abounding in the River Hugli the susu is extremely difficult 

 to procure, at least in the vicinity of Calcutta ; and too often when a 

 fine example is taken the captors saw off the rostrum, rendering it 

 useless for a museum specimen. In what I believe to be the adult 



* Since the above was written Capt. Jethro Fairweather, commandino^ the ship 

 * Forfarshire,' has favoured us with the skull of a small but not young Steno, which 

 seems to be S. attenuatus of Gray. It was procured not far from the Sandheads, out of 

 an innumerable herd of them, " as far as the eye could reach in all directions," and was of 

 a paleish lead-colour ; not therefore, however, the Delphinus raalayanus var. plumbeus, 

 which is a much larger species common in the Bay. Teeth |? — ^. Major R. C. 

 Tytler, also, has presented a skull taken west of the Cape of Good Hope, which agrees, 

 or very nearly so, with the two heads minus the teeth and the lower jaw, mentioned in 

 the text.
