inusculns. The adult skulls, with teeth half worn or more, 

 range in condylo-basal length between 20-3 and 23 mm. ; 

 they are thus distinctly larger than in ordinary House Mice, 

 and agree closely in size with those of M. vmralis from 

 St Kilda ; we have carefully examined their proportions and 

 structure, but can find no tangible difference, other than the 

 unusually large size, from the skull of M. musculus. The 

 mesopterygoid space is quite as in the latter species. 



B. Barvas. — Four House Mice were collected here by 

 Mr Hony : of these Nos. i, 3, and 4 were taken" in a kitchen 

 garden near manse," while ^o. 21 was obtained on a grassy 

 bank at some distance from houses. The dimensions taken 

 in the flesh are : — 



These specimens differ in no way from ordinary M. 

 musculus. 



Cetacea stranded on the Scottish Coasts. — A Report on 

 Cetacea stranded on the British Coasts during 19 15, by S. F. 

 Harmer, published under the auspices of the British Museum 

 (Natural History), was issued in February last. Owing to the 

 abnormal conditions of wartime, only twenty-eight specimens were 

 reported, but among them appear three Scottish records, namely, a 

 Bottle-nosed Whale {Hyperoodon rostratus) at Thurso on 14th 

 March, a Porpoise (presumably the common species) at Arbroath 

 on 7th July, and a Sowerby's Whale {Mesoplodon bidens) at Inver- 

 ness on I 3th August.
