84 Mr. J. E. Gray on the British Cetacea. 



8. Delphinorhynchus Sowerhyi ; Physeter bidens, Sow. Brit. Misc. 

 1. 1; D. Sowerbyi, Desm. ; Delphinus micropterus,Cvi\\GY, R. A., 

 F. Cuv. Cetac. t. 8. f. 1, t. 7. skull ; D. Dalei, Lesson. 



Mr. James Sowerby at once recognised the skull of this animal 

 in the figures of the skull of Delphinus micropterus above cited, 

 so that this species was described and figured by Sowerby many 

 years before its appearance on the coast of France. The French 

 authors have universally overlooked the form of the head and 

 position of the dorsal, and erroneously referred Sowerby^s figures 

 to Hyperoodon. 



9. Delphinus Delphisy F. Cuv. Man. Lithog. 



We have three specimens from the British coast in the British 

 Museum. 



10. Delphinus Tursio, Hunter, Phil. Trans. Ixxxvii. t. 18 ; D. 

 truncatus, Montague, Wern. Trans, iii. 75. t. 3. 



0. Fabricius and Montague described this species as whitish 

 beneath ; Schlegel figured it as black above and below. 



I have a drawing made by R. Templeton, Esq., from a speci- 

 men caught on the south coast of Ireland ; it is not in Thompson's 

 list of Irish species. 



1 1 . Lagenorhynchus albirostrisy Gray, Zool. Erebus and Terror, t. ; 

 D. Tursio, Brightwell, Ann. and Mag. N. H. 1846, t. 2. 



Mr. Brightwell has kindly sent me for examination the head 

 of his specimen ; the nose is not longer than the length of the 

 brain-cavity, and rapidly tapers in front with concave sides. The 

 teeth are not half the size of those of D. Tursio, and it is at once 

 distinguished from that species by the whiteness extending to 

 the upper part of the beak. This and Grampus Cuvieri are most 

 interesting additions to our fauna. We have the skulls of two 

 other species of this genus in the British Museum collection. 



12. Orca gladiator ', Delphinus Orca, Linn., Schlegel, Abhand, 

 t. 7 and 8. 



Hunter's figm'e (copied by Bell) has the spot over instead of 

 behind the eye. The figure in the ' Mag. Nat. Hist.' is better 

 in this respect. 



13. Globiocephalus Melas, Lesson ; D. Melas, Trail; D. deductorj 

 Scoresby ; D. globiceps, Cuv. 



The skull of the specimen described by Dr. Trail was recently 

 sent by that naturalist to the British Museum, and we have also 

 a young specimen.
