showed : — (1) that C. antarcticus and C. latrans are not closely 

 related, as have been claimed ; (2) that the affinities of 

 C. antarcticus lie with certain South- American species of Oanidee ; 

 and (3) that C. latrans must be affiliated with the wolves and 

 large jackals of the northern hemisphere. These conclusions 

 were based mainly upon cranial and dental characters, and the 

 points were illustrated by a series of lantern-slides of the skulls 

 of several species of Canidse. 



A paper by Major G. E. H. Barrett-Hamilton, F.Z.S., and 

 Mr. Martin A. 0. Hinton on a collection of Mammals from the 

 Inner Hebrides, was read by Mr. Hinton, This collection had 

 been made during an expedition organized and managed by 

 Mr. W. K. Ogilvie-Grant. Three new forms were discovered : 

 of these one \Sorex grantii) is regarded by the authors as an 

 insular development of S. araneus, whilst they are inclined to 

 think that the other two {Evotomys alstoni and Microtus agrestis 

 macgillivrai) are slightly modified survivals from the Pleistocene 

 period. 



SoREX grantii, sp. n. 



Habitat. Islay, 



Size rather large (average : head and body 77'3, tail 36, hind 

 foot 12-6 mm.; condylo-basal length of skull 18-2 to 19-3 mm,); 

 colour pattern, the dasky upper side in strong contrast to light 

 flanks ; dentition, posterior unicuspid above frequently suppressed, 

 the four remaining unicuspids being then enlarged in compen- 

 sation. 



Evotomys alstoni, sp. n. 



Habitat. Mull. 



Size slightly larger than in E. glareolus, approaching that of 

 norvegicus ; tail shorter than in latter, about as in former ; ear 

 and colour nearly as in glareolus ; hind foot as in norvegicus and 

 skomerensis (dimensions of type : head and body 108, tail 44, hind 

 foot 18, ear 11 mm.). Skull large as in norvegicus (condylo-basal 

 length 24'l-25'3 mm.), jugal heavy, bi^ain-case broad and smooth, 

 convex above in profile instead of flattened, rostrum and bullae 

 like those of norvegicus; posterior cheek-tooth above with the 

 third inner fold and fourth inner salient angle well developed. 



MiCROTUS agrestis macgillivrai, subsp. n. 



Habitat. Islay. 



Similar to M. a. exsul in size and general proportions ; coat 

 much thinner, the amount of yellowish wash on underside much 

 less, so that slaty bases of hairs take part in general coloration, 

 the upper side slightly less brightly coloured ; dental characters 

 conspicuously of the exsid type ; skull (the comparison being 

 between skulls of equal age) with deeper rosti-um, lighter jugal, 

 less sloping occiput, and less reduced interparietal, the anterior 

 portion of temporal muscle not ascending so high upon the
