I'TEROrrS XEOHIBKRNICUS. 



Least width of furred tn-e;i of back in fully ndult specimens nlioiit 

 15-25, in iinraature individuals not infreqnentl)' 35-45 inni. 



Colour. — ^ ad., eotype, New Irelan(i, 4994 (Berlin Museum ) : 

 Back and rump uniform deep russet. Poreneck, breast, belly, and 

 Hanks russet, ratlier paler than npperside, everywhere sparsely 

 sprinkled with shiny bnffy or silvery greyish hairs ; foreneck and 

 bides of neck slightly washed Avith chestnut. Mantle and occiput 

 tawny-ochraceons. Crown, sides of head, and throat dark chestnut. 



Individual variation rather considerable, chiefly depending on 

 i.he darker or ])aler tinge of the colour, and on the greater or 

 less admixture (rarely complete predoruinance) of butf'y hairs 

 on the back : — General colour of back varying in most specimens 

 from pale russet, through russet, to deep mars-brown, neaily 

 always more or less conspicuously sprinkled with bntf'y. The 

 colour is sometimes uniformly and thinly sprinkled with buffy, but 

 [^•cnerally darkest (less mixed with buffy) along sides of back and 

 rump and on upper side of thighs, palest (more thicklj' sprinkled 

 with buffy) along middle of back and rump. The palest specimen 

 examined is practically uniform yellowish buffy on back 

 and rump, these portions of the fur being as pale as the 

 mantle ; the opposite extreme is represented by specimens with 

 deep mars-brown back and rump strongly contrasting Avith brighter 

 mantle, and by one specimen with sides of back and rntnp and 

 upper side of thighs dark vandyck-browu contrasting with yellowish- 

 butl'y median spinal tract. — Breast, belly, and flanks varying from 

 nearly uniform pale ochraceous, throngh tawny, to russet or even 

 mars-brown ; flanks, sides of breast and belly, and anal region oc- 

 casionally somewhat darker than centre of breast. Hairs on under- 

 side of membranes dark russet or mars-brown. — Occiput and mantle 

 rarely as light as yellowish bufl'y or yellowish cream-buff, generally 

 some tinge of ochraceous-bulf or rich ochraceous, sometimes washed 

 with tawny. Sides of neck and foreneck generally quite or nearly 

 similar to breast and belly. Top of head generally darker than 

 occiput, more washed with tawny or russet or even mars-brown. 

 In many specimens this darker shade extends neai'ly uniformly 

 over the crown, interocular space, and sides of head, often sprinkled 

 Avith buffy or silvery hairs ; in others it more or less approaches 

 the shape of an ill-defined T, the vertical bar extending forward 

 between eyes, the cross bar occup\ing the crown in front of the 

 ears; and in a few specimens (among these the type of Pt. coro- 

 n(l^^ts) the dark T-mark is unusually conspicuous and well-defined. 

 In this latter case the markings of the upper side of the head 

 strangely suggest the style of markings in Pt. aipistratus. 



Se.riial diffa-entlation. — Canines generally consi^icuously larger in 

 males than m females. 



Measurements. On pp. 390, 391. 



Specimens examined. Thirty-geven, in the collections of the Berlin 

 and British Museums, including the cotypcs of the species and the 

 typos of Pt. dejener and Pt. coronatus.
