1897.] ox ABNORMAL SKULLS OF GOAT, BULLDOG, AND PTG. 473 



Mr. E. E. Holding exhibited and made remarks upon a skull of 

 the Theban Goat, Capra Mrcus, var. thehaica, a hornless variety 

 of the domesticated Goat peculiar to North Africa and Egypt, 

 which presented a curious shortening of the anterior portion of 

 the skull, the premaxilla and maxilla being considerably reduced. 

 The nasal bones, curved, and separated throughout their entire 

 length from these bones, were articulated only Aiith the frontal 

 bone, and exposed the base of the turbinated bones in the interior 

 of the nasal cavity. The lower jaw remaining the normal length, 

 the incisors projected considerably beyond the premaxilla, pre- 

 venting the animal from obtaining its food by the ordinary 

 method of grazing. 



A. Theban Goat. 



B. English Goat. 



Mr. Holding also exhibited a fine Bulldog's skull and the skull 

 of a Pig which indicated a similar arrest in the development 

 of the anterior portion of the skull, due directly to selective 

 influences. 



Mr. Tegetmeier and others took part in a short discussion on 

 this subject.
