a larger tooth, though, owing to the youth of the animal, it is 
not yet in the same position as the one shown in the skull of 
T. cynocephalus. 
The existence of a second Thylacine has been known to old 
residents in Tasmania for years past, as they were in the habit 
of distinguishing the two kinds by the names of Greyhound- 
and Bulldog-Tiger. Mr. George Masters, Assistant Curator 
of the Australian Museum, has spent some nine months on 
the island ; and being anxious to clear this matter up, he col- 
lected about twenty-six skulls, two of which belong to the 
Thylacine for which I now propose the name of breviceps. 
I shall, on a future occasion, give you a fuller account of 
the excellent collection made by Mr. Masters.

Mr. OsBert SALVIN has lately sent to the British Museum a 
collection of animals in spirits, collected at Guatemala and 
Costa Rica. It contains two species of Salamandra, which 
appear not to have been previously entered in the catalogues.
