LÖNNBERG, MAMMALS FROM ECUADOR AND RELATED FORMS. 23 



Nasua olivaeea quitensis n. subsp. 



Two male specimens from below Lloa, southern slopes of 

 Pichincha, altitude 9 — 10,000 feet, April 1911, and one spe- 

 cimen from Gualea altitude about 8,000 feet, May 1910. 



The smallness of the skulls and the molars, and the pin- 

 ched in nasal region prove that these specimens belong to the 

 oli vacea- gr oup. The} T differ, however, as well with regard to 

 colour as in other respects from the t} T pical Nasua olivacea 

 Gray of Colombia (Santa Fé de Bogotå), and the subspecies 

 N. o. meridensis Thomas, 1 inhabiting the Culata Mountains, 

 Merida, Venezuela. 



The general colour of my three specimens is black, coar- 

 sely grizzled with broad subterminal yellow rings to the hair. 

 These rings are glossy, but look different in different shades of 

 light, so that they sometimes appear more golden yellow, 

 sometimes more yellowish tan colour. The whole of the 

 upper parts of the body and the sides have this grizzled 

 appearance, and there is no trace of any dorsal stripe. 

 The under-fur is very light, almost creamy white. The 

 fur is soft and thick, the longest hairs measuring 

 about 40 mm. The ocular region and the snout in front of 

 the eyes are uniform brownish black. A median black stripe 

 extends from the snout to the nape being more prominent 

 from the interorbital region and backwards, because these 

 parts are otherwise brownish grey, more or less mixed with 

 greyish white. The hairs on and around the ears are uniformly 

 black or blackish brown. The feet are dull black. The lower 

 si de of the body from the chin to the vent påle brownish grey 

 (less brown, and more grey than »snuffbrown» according to 

 Dauthenay Rep. de Couleurs 303. 1), a little lighter in some 

 places, somewhat more blackish in others, the long hairs very 

 light, as a rule. The tail is uniform black above with no trace 

 of dark rings; on the lower side, especially at the base, some of 

 the hairs have light subterminal rings.
