4404. The skull of a Blood-hound (Canis familiaris, var. sanguinarius}. 



The frontal region is rather more elevated, and more convex at the sides than in the pre- 

 ceding specimen. 



Purchased. 



4405. The cranium of a Greyhound (Canis familiaris, var. Grajus). 



This is characterized by its more slender proportions, as compared with its length, and by 

 the less elevation and expanse of the frontal region. The acoustic bullse are more expanded. 



Purchased. 



4406. The skull of a large Terrier (Canis familiaris, var. fossorius). 



It is broader than the preceding, but is one-fifth shorter, the diminished length being 

 chiefly in the jaws : the frontal region is more elevated, and the concavity greater between 

 that and the nasal. 



Purchased. 



4407. The skull of a somewhat smaller Terrier (Canis familiaris, var. fossorius). 



It shows a similar contour of the nasal region and a similar elevation of the frontal, and 

 differs from the preceding specimen chiefly in^the greater relative size of the cerebral cavity. 



Purchased. 



4408. The skull of a smaller variety of Terrier (Canis familiaris, \ar.fossorim). 



In this specimen the cerebral cavity still more predominates, and the frontal region is more 

 suddenly elevated. The first premolar and its socket are wanting in both sides of the 

 upper jaw. 



Purchased. 



440!). The skull of a Pointer (Canis familiaris, var. aviarius}. 



It agrees in size with that of the Shepherd's Dog, and differs in the greater expanse of the 

 frontal sinuses, producing a corresponding elevation of the frontal region. 



Purchased. 



4410. The skull of a Setter (Canis familiaris, var. aviarius}. 



This differs from the Pointer in the greater relative expanse of the cerebral cavity, and in 

 the shorter zygomatic arches and jaws. The premolars are more closely set. The sagittal 

 crista is less marked, and the contour of the cranium is more rounded. 



Purchased. 



4411. The skull of a Water Spaniel (Canis familiaris, var. aquaticus). 



Though somewhat smaller than the preceding, the cerebral cavity is proportionally rather 

 less ; the frontal region is narrower, more depressed in the middle, but rises more suddenly 

 from the nasal region, the orbits being a little higher. 



Purchased.
