MAMMALS FftOM TfiE INNER HEBRIDES. 936 



The size of this form is greater than that of the other rnfous 

 mice, A. h. cumbrcie and A. h. ghia, with which it was formerly asso- 

 ciated. The tails are short, and the ears are considerably 

 shorter than those of other forms of A . hehridensis. 



The only complete skull available, though that of an old 

 specimen, is noticeably small. The dimensions indicate a broad 

 rostrum like that of the Sodor (Grigha, Jura, Islay) forms, and a 

 peculiar long, narrow nasal ; in other proportions the skull seems 

 fairly to resemble that of the Cumbrae form.

Description. The black dorsal hairs are distributed, not so as 

 to dull the general colour from rufous to brown as in the Mull, 

 Islay, Jura, and typical A. h. hehridensis forms, but in more 

 definite splashes ; thus the back remains rufous with black 

 spangled more abundantly in a median position than on the 

 flanks. There is bright contrast between the flanks and the 

 silvery belly, the line of demarcation being distinct. The pectoral 

 spot is slight, though more distinct than in A. h. cimibrce and 

 A. h. tirce. 



The appendage measurements correspond to those of A. h. 

 cumbrce and the typical form. 



The skull measurements, when compared with those of ^1. h. 

 cumbrce, indicate a relatively small zygomatic breadth, crania] 

 width, and coronal cheek-teeth length. In these measurements 

 the skull of A. h. ghia more closely resembles that of the Islay 

 than that of the Cumbrae form.
