RemarTis. — Throughout Spain the characters of Arvicola sajndus 

 scqjidus are very constant ; only in the extreme north-west does 

 there appear to be any tendency toward the darker A. s. tene- 

 hriciis. The French specimens from the neighbourhood of 

 Toulouse and from the marshes near the mouth of the Rhone 

 agree with true sapklHn in the genei'al light yellowish hue of the 

 back and sides, though showing a distinct approach to tenehriciis 

 in the noticeable sprinkling of black hairs on cheeks.
