Sciurus vulgaris, Linn., Syst. Nat. ed. ig, vol. i. p. 86 (1766); 

 Bell, British Quadrupeds, 2nd ed. p. 276 (1874), 

 (Plate XIX.)

 female is smaller, and generally of a lighter colour than the

 some in which the grey predominated over the red. In April 

 and May the hair of the upper-parts assumes a singularly 

 faded appearance, losing its gloss and assuming a light yellowish 

 tint. In the latter month the process of depilation commences, 

 to be completed by the end of June, when the ears are desti-

 ears are not proportionately longer than the rest until Novem-
