with silverv-whiLe hairs. — Eieast, belly, aud Hanks dark inars- 

 browii, thickly mixed with lonf?er, coarse, and somewhat crinkled 

 huffy-white or silvery-white hairs. — Mantle and sides of neck huffy 

 clay (a shade of huffy paler than but not contrasting with huffy 

 element of colour of hack); short base of hairs vandyck-brown. 

 (jtlandular tuft on side of neck orange tawny. — Occiput and crown 

 mixed huffy clay aud dark brown, producing a general aspect 

 darker than but not contrasting with that of mantle. Region 

 above, behind, and below eyes, chin, and throat dark vandyck- 

 lirown more finely mixed with pale huffy, producing a dark brown 

 facial " mask " rather strongly contrasting with pale head. 



Individual variation in colour. — The huffy element in the colour 

 of the head, hack, rump, and underparts is in some individuals 

 completely replaced by silvery whitish-grej' (this is the case in the 

 type of the species) ; although not differing essentially in any 

 other colour character, such individuals strongly contrast in general 

 aspect with the male described above. Also the amo2(7it of pale 

 sprinkling of the fur is individually variable, hut as a rule greater 

 on the underparts than on tlie back, which sometimes is only 

 very slightly mixed with paler hairs or hair-tips. In very pale- 

 coloured individuals the light colour of the mantle and sides of neck 

 is continued across the forcneck, forming a complete collar, though 

 even in this case the lighter hair-tips on the forencck arc shorter 

 tlian on the sides of the neck. The dark facial " mask " is generally 

 cous])icuous, though in the palest-coloured individuals much lightened 

 by pale tips to the hairs. 



Scvunl differenliation. — Jloles with, females without, a tuft of 

 rigid glandular hairs on each side of neck.

Itemarlcs. — Pt. woodfordi may be readily distinguished from any 

 other species of the genus by the combination of these four characters : 

 cheek-teeth excessively narrow, ears small and nearly hidden in the 

 fur, tibia naked above, head not striped. It is undoubtedly closely 

 I'elated to Ff. scapiiJ«li(s, with wiiich it accords in all characters of 

 the skull and dentition (ajtart from the less recurved lower canines), 

 as well as in tlie number and ariangement of the palate-ridges ; 

 it differs chicdy from that species by the much smaller ears, the 

 less broadly separated wings, the practically complete sujipression 

 of the hairs on the distal portion of the humerus and the whole of 

 the forearm, the unmodified (/. e. not peculiarly long and thick) 

 hairing on the underside of tho membranes, and much smaller size. 

 In the colour of the fur it does not differ essentially from Pt. ."capu- 

 latus, but the general aspect of the coloration is to some extent 

 changed by the rather thick and coarse sprinkling, on back and 

 particularly on underparts, with huffy or silvery hairs.
