p^-m^ and p.-m3 recalling in general sM-ucture coirespoiidiii;'- 

 teeth of Ft. epularius and macrotis, but shorter, lower, and very 

 much narrower. m' and ra.j rudimentary, the former subcqual 

 to an upper incisor, the latter equal to or smaller than i„ *. 



Falate-i-idges. — 5 + 4 + 2 (or 3). — First ridge terminating laterally 

 at front of canines ; second at back of canines ; third at front of p'; 

 fourth at back of p^; fifth at middle of p^; sixth at front or middle 

 of ra' ; seventh at back of m" ; eighth and ninth behind m^ ; tenth 

 and eleventh situated at palation border. Often a more or less 

 rudimentary twelfth (the usual third posterior) ridge. 



/'Jars. — Hhape and relative size as in Ft. epularius. 



Wings. — Membranes broadly separated at origin from back, 

 interspace 35-45 mm, 



Interfemoral. — Scarcely developed in centre. 



Fur. — Short, silky, closely adpressed on back. Approximate 

 length, back 9-12, mantle 13-15, belly 11-14 mm. Furred area 

 of back broad, 4U-50 mm. at middle of back. 



Above, fur extending in a narrow line of very short closely 

 adpressed hairs along humerus and pro.ximal third or half of fore- 

 arm, generally leaving region round elbow naked. Tibia naked. 

 Lateral interfemoral furred along inner side of thigh and proximal 

 half of tibia, naked distally and along inner margin. 



Below, tibia naked, except, immediately below knee. Hairing on 

 underside of antebrachial membrane, and on lateral membrane along 

 outer side of forearm and between humerus and femur, unusually 

 long and dense. 



Colour ■ Avliole scries examined). — Back and rump glossy dark 

 brown, sometimes nearly pure Front's brown, more often approaching 

 brownish bistre ; the whole of the surface, particularly in the 

 darkest-coloured specimens, distinctly grizzled, owing to the 

 extreme tips of tlie hairs being paler-coloured, broceoli-brown 

 or hair-brown ; the arranged fur shows m certain lights distinct 

 inirplish reflections. — Breast, belly, and anal region generally dark 

 and dull Prout s brown or vandyck-brown, rarely approaching mars- 

 brown (lightest extreme), sometimes of a tinge between vandyck- 



* Probiililv owing ta the degeneration of the teeth abnormalities in tho 

 tooth fornuila, so rare in other species of the genus, are by no means un- 

 (■ommon in Ft. scapulahts. Of twenty-one skulls examined, no less tlian five 

 present deviations from the normal condition of the denlition. The most 

 frequent alicrratiou is, as might indeed be expected, tlie complete suppression 

 of tlie rudimentary iHj and its alveolus on both sides ; this is the c;ise in fo\ir 

 skulls (B. M. r.7.lb.24.1. 2 ad.; 62.5.2.3, $ imm. ; 8.8.8.4. S ad- ; 8.8.8.6. 

 5 imm.), and in one of these also the left m^ and its alveolus has disappeared 

 (8.8.8.4, J ad., teeth only moderately worn). In one specimen a supernume- 

 rary premolar is present on the left side situated in the broad diastema between 

 P; and Pj, in shnpe and size a copy of pi, in ponfion corresponding to the 

 premoliir (p.>) which is permanently missing in Chiroptera ; no tra^'e of a 

 corresponding tooth on right side (86.11.1.1. ad ). In one epecimen a super- 

 numerary premolar is present ob hoih sides betweqn p* and p'', which, to give 

 room for the additional tootb, in this specimen are more broadly separated 

 than usual ; Btruoture of .s.upernurt)erarv premolar typical Ptercpine, S'ze 

 nearly half that of p* (8.8 8.3, c ad.).
