linos alon^- the back and sides of llalf-{:fr()^vll specimens of both sexes, 

 and in a great proportion of the adult females. These lines are so con- 

 spicuous as almost to negative its otlierAvisc protective colouring. This 

 is certainly a modification rendered possible 1)}' certain c(mditions that 

 are local, perhaps the absence of some enemy present in its origimil 

 home. There are represcmtatives of the type and varieties of this si^ccies 

 in the (Tuille- Alios Museum.

 abundant in the north-west and south-west. It presents no local cha- 

 racteristics. 



MAMMALIA. 



Of Mammalia the Channel Islands possess nineteen 

 authenticated sj)ecies, but there are possibly tAventy or even 

 twenty-two, for observations have still to be made with regard 

 to the bats, and the identity of the smaller rodents and shrews. 

 The known representatives are as follows : — 



Stoat, Mvstela erminea. 



Hedgehog, Erinaceus eiiropoeiis. 



Mole, Tal])a europoea.

In the notes wdiich follow the term " indigenous " must 

 be understood to imply that the animal thus defined has 

 reached the islands in the natural course of distribution ; in 

 other words, that there is no reason to suspect its having been 

 introduced by human agency or by accident. 



Stoat. (Local name the same as the French for weasel, Belette.) Occurs in 

 Jersey and Guernsey, where it is fairly common and generally diffused.
