250 A PRELIMINARY LIST OF THE MAMMALS 
Family—LEPORIDA 
Common Hare (Lepus simidus, Linn.)/ 
Rabbit (Lepus cuniculus, Linn.) I have seen two very extra- 
ordinary cases of malformation of the incisor teeth, owing to a 
curious deformity of the jaws, both of which are in the Museum 
Collection. The one, received from Mr. A. C. WoLiEy Dop, 
has the left lower jaw contracted, so that the right lower incisor 
(Scalpyriform incisor) is brought to bear on the left upper incisor, 
consequently leaving the two remaining incisors free, with the 
result that they have grown to twice their natural length, and 
are curved outwards. The second example, received from 
Mr. R. J. Smiru, of Aldford, is still more extraordinary. In 
this example the four incisors have all grown to an enormous 
length, especially the right lower one, which reaches to the top 
of the nose, and measures 1} inches; the opposite upper tooth 
has taken an unfortunate direction, curving inwards into the 
mouth, which must have given the animal great pain, and 
rendered mastication almost impossible. Curiously, in both 
examples, the inner or accessory incisors had not grown very much 
beyond their usual length. How these animals existed with 
such a dentition is extraordinary, and more especially so as they 
were both full-grown animals. 
RUMINANTIA. 
Family— CER VID 2. 
Fallow Deer (Cervus dama, Linn.) Semi-domesticated. 
Family—BOV/IDZ. 
White Wild Cattle (Bos taurus, Linn., var. Scoticus.) 
There is a fine herd of these animals at Vaynol Park, Carnar- 
vonshire, the property of AssHETON SmitH, EsqQ., which the 
Members of this Society had the privilege of seeing in 1891, by 
kind permission of the owner. The once celebrated herd at 
Lyme, in Cheshire, have become extinct. I cannot do better 
than refer the reader to Mr. Cuas. OLDHAM’s article in the 
Zoologist for 1891, pp. 81-87, which gives a full account of 
the herd. 
CETACEA (OponrTOCcETI.) 
Family--DZLPHINID. 
Porpoise (Phocwna Communis, F. Cuvier.) Sparingly off the 
Welsh Coast. A specimen taken at Colwyn Bay in November 
1891 was presented to the Grosvenor Museum by Mr. A. O. 
WALKER. I have seen many specimens off Bull Bay, Anglesea, 
and they often occur in the Mersey below Eastham. 
In Zhe Fauna of Liverpool Bay (Rept. ii., pp. 134-51), the late 
Mr. T. J. Moore has given a “ Report on the Seals and Whales 
(Pinnipedia and Cetacea),” of the district, containing much 
interesting information.
