has mentioned as existing in the single specimen on which he based the name is 
present irl all my specimens.!' Around the eyes a more or less defined fawn coloured 
ring is to be seen. The sides of the head is otherwise nearly similar in colour to 
the lower parts. The hair of the tail is black with white tips and three yellow rings. 
The colour of these rings is, when the tail is in fresh pelage, most similar to »Mars 
yellow» (»Rép. de Couleurs>, 316), sometimes more yellowish tan, sometimes inclining 
to fawn. The tip of the tail looks almost black because the white tips to the hair 
are absent there and the light rings more or less reduced in number. The upper 
one is absent, and sometimes the two others as well. 
The length of the skins (head and body) is 22—25 cm. 
The length of the tail varies from 22 to 26,5 cm. 
The length of the hind foot is about 48—50 mm. without claws. 
The maximum length of the skulls varies from 52,5 to 55 mm. 54 being the 
usual size of old specimens.

All these specimens are fully adult with worn molars. They are from the forests 
near Meru boma. The specimens from Kenia have the same dimensions. 
As the dark fur indicates, this Squirrel is an inhabitant of the dark and thick 
forest. Often two or three specimens were found in company, and at least once it 
was stated that both were adult females. They appear thus to be sociable inde- 
pendently of sex.

The type specimen of P. jacksoni is stated to be from Kikuyu, while the type 
of P. j. capitis is from Nairobi Forest. I have collected six specimens from the 
! Mr. R. B. Woosnam showed me a pair of dark Squirrels shot near Escarpment which had no such 
white throat mark. As they otherwise resembled the Kenia Squirrel it is probable that they only represented 
a melanistic phase of the same. |
