260 DELPHINID^. 



flat. A skeleton in the Surgeons' Hall of Edinburgh, from the same 

 locality, has them all acute. The latter is named D. Delphis. The 

 atlas (or first) and second cervical vertebrae united by the body and 

 lateral processes ; the third to the seventh cervical vertebrae free. 



A specimen with teeth %\, large, conical, acute, was taken in the 

 Eivcr OrvveU, May 10, 1849. 



Mr. Charles D. Meigs described the foetus of Delphinus Nesarnalc, 

 Journ. Acad. Nat. Sci. Philad. i. 267 ; see Arch. Naturg. 1832, 64. 



Col. Montagu described an old specimen, taken on the 3rd of July 

 1814, in Duncannon Pool near Stoke Gabriel, about five mUes up the 

 river Dart, as D. truncatus (Wern. Trans, iii. 75. t. 3). It was 

 12 feet long. The skull, which came into Montagu's possession, is 

 now in the British Museum. 



Pirst described as British by John Hunter, under the name of the 

 Bottle-nose ^VTiale, in the ' Phil. Trans.' for 1787, t. 18. It was 

 caught on the sea-coast near Berkley, and the skeleton is now in the 

 Museum of the College of Surgeons. 



Mr. Jenyns mentions one observed by Mr. Gilbertson in the river 

 at Preston in Lancashii-e (Manual, p. 41). 



The skeleton of this species is described by Professor Owen from 

 a female specimen taken at the Nore, June 1828, in company with 

 a male. " It survived many hours after having been dragged out 

 of the water, during which time it emitted a sound not unlike the 

 bellowing of a calf." — Cat. Osteol. Series Coll. Surg. p. 449. n. 2483. 



Professor Owen observes that Cuvier assigns to Delphinus Tursio 

 from 42 to 46 teeth in each jaw ; so that the teeth seem to vary from 

 40 to 50 in each jaw. 



In a second skull in the same collection (no. 2484) " a greater por- 

 tion of the crown is worn away in all except the last two or three, 

 and a large proportion of the unenameUed fang is exposed, upon 

 which their more oblique position and larger proportionate size 

 appear to depend" (p. 451). 



In the same collection (no. 2485) is " the skuU of an apparently 

 aged specimen, with a disease of the jaws ; all the teeth are lost, 

 and the sockets are obliterated, except at the anterior part of the 

 alveolar tracts, where they are very shallow." 



The axis and atlas coalesced (nos. 2483, 2488). " The cervical 

 vertebrae are very thin, and separate. Vertebrae 41, of which 13 are 

 dorsal. First bone of the sternum not pierced, with blunt lateral 

 angles. Bladebone with the acromion larger and more rectilinear 

 with the spine than in B. Delphis.''' — Cuvier, Oss. Foss. v. 305. 



" This species is not so beautifully marked with lines as the 

 D. Delphis, The snout is much shorter, the upper jaw not so long 

 as the lower. The dorsal fin smaller cmd more posterior, as I noticed 

 in a specimen inspected at Plymouth. The eye appears small, and is 

 placed more directly over the angle of the mouth ; the teeth small, 

 conical, 23 on each side." — Couch, Cornish Whales, 39. 



Tursiops Tursio is not so rare as Grampus Hissoanus, but far less 

 common than Delphinus Delphis. M. Gervais has specimens taken 

 in the Gulf of Lyons, especially at Cette and La NouveUe, and at
