Presented by Governor Sir George Grey, C.B.

4393. The skeleton of the large variety of Mastiff called Mount St. Bernard's Dog 

 (Canis familiaris, var. anglicus).

Presented by G. J. Guthrie, Esq. 



4394. The skeleton of a Greyhound (Canis familiaris, var. Grajus}. 



It is characterized by the more slender proportions of the bones. Four vertebrae are 

 anchylosed to form the sacrum. The bones of the trunk are larger, and those of the extre- 

 mities longer, in proportion to the head, than in the Dingo. 



Mm. South. 



4395. The skeleton of the Italian Greyhound (Canis familiaris, var. italicus). 



This small and slender variety of Dog is chiefly distinguished by the disproportionate size 

 of the cranium, and the absence of the cristae and ridges on its external surface, which cha- 

 racterize the larger and stronger varieties. 



Presented by Sir Anthony Carlisle, F.R.S. 



4396. The skeleton of the fetus of a Shepherd's Dog (Canis familiaris}, wanting 

 the tail. 



It shows the narrow triangular interparietal ; the separation of the neurapophyses from 

 each other and from the centrum in the trunk-vertebrae ; the extent of ossification in the ilia 

 and ischia, whilst the pubis remains cartilaginous ; the great disproportion of the cranium 

 over the face, and the equal extent of the maxillary bone, behind the suborbital foramen, to 

 that which is in front of the foramen. The tympanic bone presents the form of a simple 

 ring. 



Mus. Brookes. 



4397. The skull of a Wild Dog (Canis familiaris). 



It differs from that of the Dingo, No. 4390, by the greater development of the frontal 

 sinuses, and the corresponding increase in height and breadth of the frontal part of the 

 cranium. 



From the Himalaya Mountains.
