tibia clothed above (though not very densely so). Back bl■o^v^lisll, 

 underparts paler, mantle ocbraceous. Porearm 113-lii2 mm. 

 Bah. Lombok ; Flores. 



Skull (compare fig. 13, p. 270, skull of Pt.soUtarms). — Deflection 

 of brain-case moderate, alveolar line if projected back'ward passing 

 through upper part of occipital condyle. Sagittal crest, if de- 

 veloped, very low; even in perfectly adult individuals (teeth worn) 

 the temporal crests, though closely approximated, are sometimes 

 not quite united together to form a sagittal crest, llostrum un- 

 usually short and heavy ; front of orbit vertically above posterior 

 half of p'. Postorbital processes long and slender, sometimes almost 

 reacliing, or even completely fused with, corresponding processes 

 of zygomatic arch. Coronoid height of mandible subequal to 

 (a liitle smaller or larger than) length of lower tooth-row, c-m^. 



Teeth (compare tig. 13, p. ii70, dentition of Pt. solitarius). — 

 Cingulum of up]>er canines forming a well-defined, narrow ledge, 

 p' rudimentary, though slightly less so than in the allied species ; 

 generally a terete spicule, in some specimens with crown very 

 slightly differentiated from shaft; present in all skulls (seven) 

 examined, some of which have the teeth well worn, but probably 

 deciduous in a higher age. Posterior ledge of p' and p' distinct, 

 but short and not very sharply marked off from tooth ; in p^ a 

 minute notch, postcro-externally at base of main cusp, is generally 

 pi'esenr, indistinctly separating tlie ledge from the outer main 

 cusp ; in })' the ledge is practically confined to the postero- 

 internal portion of the tooth, which therefore extends much further 

 backward than the postero-external corner; owing to this, the 

 line of the posterior margin of p^ if projected inward would 

 pass through the middle, or the posterior half, in some specimens 

 even through the posterior point of m' on the opposite side, m' 

 almost twice as long as broad, m'' much reduced in size, subequal 

 to ij. — ij smaller than usual, one-fourth to one-sixth the bulk 

 of ij. Cingulum of lower canines forming a well-defined, narrow 

 ledge, rather more sharply defined than in upper canines, 

 p, lafge, once and a half, sometimes almost twice the size of i„. 

 Posterior ledge of p, and p^ short, in p., rather distinctly though 

 not sharply marked off from tooth, in p^ ill-defined, va^ reduced, 

 much smaller than p^, subequal to m^ and i... 



I'alate-ridijcs (one specimen, Flores). — 5 -f- 6 -f- 3. First ridge 

 terminating laterally at front of canines ; second at back of 

 canines ; third at front of p' ; fourth at front of p^ ; fifth at middle 

 of p* ; sixth at front of m' ; seventh at m" ; eighth to eleventh 

 behind m" ; twelfth to fourteenth situated at palation border. 



Ears. — Not reaching hinder corner of eye, when laid forward. 

 Inner margin evenly convex from base to tip ; outer margin flatly 

 convex in lower, flatly concave in upper half ; tip narrowly 

 rounded ofi'. Xaked behind, except at base. 



Tnterff moral. — Extremely short or undeveloped in centre. 



Fur. — Piather short and adprcssed on back, spreading or a little
