Remarks. — This is the bright-coloured squirrel of Central 

 Europe, ranging from Germany eastward through Austria- 

 Hungary to Roumania. In Sv/itzerland it apparently inter- 

 grades with aS'. vulgaris italicus, in which the brown piiase is 

 dominant, but the exact relationship between these two forms 

 is not yet clearlji understood, and for this reason I have 

 omitted the Swiss specimens from the list of material examined. 

 To this animal and the next the name rufus lias been applied 

 by Barrett-Hamihon and Trouessart, but Kerr's Sciurus vul- 

 garis rufus * is strictly a synonym of S. vulgaris vulgaris, 

 and tiierel'ore cannot be used in this sense.

Diagnosis. — Similar to Sciurus vulgaris rutilans, but with 

 colour in red phase darker and less bright, the body cinnamon- 

 rufous strongly tinged with chestnut in summer, hazel t much 

 suffused with dull light smoke-grey along sides in winter; 

 tail at all seasons a light bright chestnut (Ridgway), Brown

 striction 15'4 ; rostral breadth at front of na^^als 7*4 ; nasal

t In the type the exact shade of the red is slio;htlv paler than hazel, 

 but the general effect produced by the light and dark annulations is 

 interniediatc between hazel and chestnut.
