84. Mr. J. E. Gray on the British Cetacea. 
8. Delphinorhynchus Sowerbyi; Physeter bidens, Sow. Brit. Mise. 
t.1; D. Sowerbyi, Desm. ; Delphinus micropterus, Cuvier, 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 Delphis, F. Cuv. Man. Lithog. Se 
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. i. 75. t. 3. 
QO. 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. : 
11. Lagenorhynchus albirostris, 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 figure (copied by Bell) has the spot over instead of 
behind the eye. The figure in the ‘ Mag. Nat. Hist.’ is better 
in this respect. 
18. Globiocephalus Melas, Lesson ; D. Melas, Trail ; D. deductor, 
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.
