I'TEKOITS GlGANTEtlS. 327 



Nepal, Assam, and Manipiir. Hairy space of back much restricted 

 in width, owing to fur extending very little (about 10 mm.) beyond 

 line of origin of membranes ; width of furred area about 4G ram. 



Above, proximal fifth of forearm thinly clothed with short 

 adpressed hairy, excepting region round elbow, which is naked ; in 

 Jiome spe<imeiis the whole of the forearm appears to he entirely 

 naked. Tibia naked. Interfemoral hairy in centre and along inner 

 side of femur and proximal half of tibia; broad inner margin of 

 membrane naked. — Beneath, tibia naked. Length and distribution 

 Dt woolly hairs on membranes as in Pt. riifus. 



Colour. — Whole series of skins, males and females, adult and 

 immature ; — Back some shade of seal-brown, sometimes of a blackish 

 tinge, sometimes more approaching dark vandyck-brown, nearly 

 always very ihiiily and inconspicuously sprinkled with greyish- 

 white hairs. In some individuals the rump is distinctly washed 

 wilh vandyck-brown, this tinge extending oci.-asionallj- also to 

 sides of back along memhranes. — Breast and belly always much 

 paler than back, but actual tinge varying considerably individually : 

 lightest extreme api)roaching golden buff, average si)eciraens ratlier 

 darker butfy, moie or less washed or blotched with tawny or 

 cinnamon-rufous, darkest extreme almost russet, lightened with 

 bufl'y in centre of bix-ast. Concealed bases of hairs always dark 

 .seal-brown. Fl niks generally conspicuously darlier than breast 

 and belly, a shaile of vandyck-brown lightened with buffy. tawny, 

 or riisset tips to the hairs. — Mantle always strongly contrasting 

 with back, varviui^' from golden buffy (lightest extreme), thrtmgk 

 ochraceous-buffy and ochraoeous, to tawny or even taw^ny clouded 

 with cinnamon, (ienerally palest posteriorly in a transverse line 

 across shoulders, Imt sometimes uniform in shade. Sides of Ufck 

 generally of a rather deeper shade than, but occasionally similar to, 

 mantle. Eorcnei k rather darker than, sometimes similar to, sides 

 of neck. Hairs on sides of neck aixl foreneck generally with con- 

 •cealed seal-'browu bases, but sometimes uniform biight-coloured 

 to extreme base. On glandular ncik-tufts in males, see below 

 (secondary sexual char-acters). — Crown and interocular space rarely 

 as bright as mantle, generally consi)icuoi\sly darker, varying from 

 ochraceons or deep ochraceous-hnff to tawny or even russet or 

 chocolate. Temporal region similar to or rather darker than 

 erown. MuE/.le, cliin, and throat lilackish, or blaekish more or 

 less lightened by admixture of vandyck-brown. 



The two subspecies of 1^. i/u/aritens are alike in colour. 



Secondari) se.-CKal charmters. — Males, adult as well as immature, 

 difier from females m having u tuft of rigid glandular hairs on 

 •each ."vide of neck, in front of antebrachial membrane. Hairs i" 

 these tufts not dift'eiing in length and scarcely in colour from 

 surroundiRg fur, though soTOetimes slightly warmer in tinge and 

 with a rather more jji-onounwd oily gloss : therefore nmeh more 

 easily detectable by the liand (rigidity of hairs) tlian by the eye. 

 The sex of a skin, if otherwise doubtful, can always be safely 

 "Icleruiinrd by the i)re.sence or absence of tlioKc nook-t4ilts. l)obsoii"ii
