S432 The Zoologist— March, 1873. 



North Sea, perhaps from the coast of the British Islands. It 

 occurs in Sweden. Gervais considers the development and 

 callosity of the vomer on which the genera Epiodon and Petro- 

 rhynchus had been founded merely an accidental variety. It may 

 be sexual, but I believe it to be distinctive, as its non-development 

 is characteristic of Epiodon australis, and the development of 

 P. capensis. I had believed it might be sexual, but the inner 

 edge of the intermaxillaries of the animal figured by Doumet, 

 which appears to be that of a female, figured by Gervais, is dilated 

 and raised, which shows it is not a character of the female sex. 



Aliama Desmareslil, Gray, from Delphinus Desmaresiii, Risso, 

 Hist. Nat. Eur. Merid. iii. p. 24, t. 2, f 3 (female), from Nice, peculiar 

 for having a long, conical head and large fins, is an animal that is 

 quite unknown to modern zoologists. It has the long fins on the 

 lower part of the side of the body of the grampus, the teeth of 

 Ziphioid whales, and a conical head peculiar to itself. 



Family XIII. Ziphiid.e. — Skull beaked. Maxillaries not dilated 

 above. Intermaxillaries linear, rather swollen on the sides of the 

 nostrils. Teeth on the side of the lower jaw compressed. Cervical 

 vertebrae more or less united into a consolidated mass. 



i. ZiPHius. — Teeth two, in the middle of the sides of the lower 

 jaw. Teeth of the male large, short, compressed, truncated at the 

 end; of female small, curved. Lower jaw often with sundry rudi- 

 mentary teeth, gradually tapering in front. Symphysis elongate, 

 and reaching to the middle of the teeth in the male, and beyond it 

 in the female. Cervical vertebrae free. Scapula with large coracoid 

 and acromion processes. 



1. Ziphius Sowerbiensis{lhe Ziphius). — Inhabits British Channel, 

 Irish Sea, and North of Scotland. Elginshire, 1800 (male) ; Brodie. 

 West coast of Ireland (males) ; Andrews. West coast of France 

 (females); Blainv. Ostend ; Dumorlier. 



The Neoziphins europajus, the skull of which is figured as 

 Diplodon europajus, Gervais, Osteog. Cet. t. xxiv., is also found on 

 the Coast of France, and may very likely occur on the British coast. 

 It is immediately known by the very short symphysis of the lower 

 jaw, and the teeth being very near its front end. 



It is curious that Linnajus, in the 'Fauna Suecica' (1861) gives 

 Monodon monoceros and Balaina myslicetus as inhabiting the
