Type. — Cambridge University Museum, No. 866e (No. 2, 

 Nehring) ; skull and part of a skeleton. Paratypes, No. 866e, 

 four skulls and portions of skeletons. Presented by Dr. H. 

 Gadow. 



Type locality. — Caves near Athouguia, Estremadura, Portugal. 



Characters. — Distinguished from L. lemmus by broader 

 molars and alleged greater breadth of coronoid process of 

 mandible. 



Remarks. — This nominal subspecies is based upon some 

 remarkable specimens believed by Dr. H. Gadow to be mummies 

 found by him in the dusty soil of some caves near Athouguia, 

 Portugal. Dr. Gadow collected his specimens in 1886, but seems 

 to have paid little attention to them until the early part of 1895, 

 when he handed them (or what he took to be them) over to 

 Major Barrett-Hamilton for determination. On March 3, 1896, 

 Barrett-Hamilton exhibited what was left of the mummies 

 before the Zoological Society of London and made the following 

 remarks : — " Thinking the remains were those of Voles I put 

 them aside for a time ; but later on, when I had an opportunity 

 of examining them more carefully, I found, to my surprise, that 

 they consisted of some skeletons and detached bones of the 

 Norway Lemming, Myodes lemmus. When first received by me 

 the remains consisted of a good many fragments and single 

 bones, and of two almost complete skeletons. These latter were 

 completely enveloped in the original skin, which had become so 

 dried and hardened that in order to enable myself to examine 

 the skeletons I had to get it removed. The whole appearance of 

 the specimens was so fresh that, unaware as I was of their true 

 character, I had the dried skin, which enveloped them like 

 mummies, removed, so that, I regret to say, not one of these 

 most interesting specimens has been preserved in the condition 

 in which I received it. Some of the vertebrae, however, are 

 still connected together by the dried remains of the ligaments. 

 This, and the whiteness and excellent preservation of the bones, 

 will show how easy it was to be deceived as to their nature, and 

 to come to the belief that they were of recent origin and perhaps 

 unimportant. . . . The present skulls resemble those of recent 

 Lemmings very closely indeed. ... I cannot find any characters
