On new Voles from the Inner Hebrides, Scotland. 361 



extent of hair above and below over I inches; the base 

 coloured like the back. 



Hub. Eastern Ecuador. Type from Sarayacu on the 

 Pastasa River. Another specimen from Canelos, on the 

 Bobonasa, alt. 2100'. 



Type. Adult male. B.M. no. 80. 5. 6. 75. Collected by 

 Mr. Clarence Buckley. 



From the dnll-coloured Ph. I. cicur of Santa Malta and 

 Bogota this subspecies differs by its greyer hips and the 

 greater difference between the upper and lower extent of the 

 hair of the tail ; but it is no doubt intermediate in character 

 as in locality between ornatus and cicur. 



XLI1. — Three new Voles from the Inner Hebrides, Scotland. 

 By G. E. 11. Bakrett-Hamilton and Martin A. C. 

 Hinton. ' 



In a paper recently read before the Zoological Society we 

 uave an account of a collection of small mammals from the 

 Inner Hebrides. This was made by Mr. it. W. Sheppard in 

 1912, working under the direction of Mr. W. R. Ogilvie- 

 Grant, who organized and managed the expedition. Early 

 in the present year Mr. Ogilvie-Grant arranged with Mr. D. 

 Anderson and Mr. P. D. Montague to continue the field-work. 

 Mr. Anderson went to the Outer Hebrides and subsequently 

 to Bum and Eigg, while Mr. Montague visited Skye and the 

 neighbouring islands of Itaasay, Muck, and Eigg. Later, 

 Mr. C. 11. B. Grant completed the work in Skye. The 

 resulting collections are of great importance, and when fully 

 worked out will throw much light on several obscure 

 problems. In the present note we have to describe a new 

 species of Eootomys from Raasay and two new subspecies of 

 the Microtus agreslis group, one from each of the islands 

 Eigg and Muck.
