122 MR. K. ANDERSEN ON BATS [May 16, 



natural grovips (sub-sections) : the lejyidus-type, the mino7'-type, 

 and the subbadius-tjpe. 



I propose to characteinse these types at once. It will enable 

 nie to confine the diagnoses of the various species to the points in 

 which they differ from the subjoined general characteristic. 



(1) The lepichcs-tjTpe. — Chief charactei-s : skull larger, width of 

 brain-case about 7'7-7'8 mm. ; connecting process (in side view) 

 projecting as a small, erect triangle (not curved forwards as a 

 sharply pointed " horn "). 



Description, based on Eh. lejndus (Wynaad, Mysore, Indian 

 Peninsula). — Supplementary leaflet as in simplex and its allies. 

 Horse-shoe not completely coveiing the upper lip ; a small tooth- 

 like projection on either side of the median notch ; front border 

 sometimes, not always, slightly crenulate (individual variation). 

 Sella decidedly broader at base than at summit, slightly, but quite 

 distinctly, constricted at middle, narrow at summit : there is a 

 tendency towards pi-oducing an almost subacute summit to the 

 sella (compare with this the borneensis-type : sella broadly rounded 

 ofl', or even truncated, at summit) ; height of sella 3"2 mm. ; 

 width at base, at constriction, and at summit : 2, 1*8, and 1*2 mm. 

 Connecting process projecting as an acute, sometimes only sub- 

 acute, triangle beyond the summit of the sella. Lancet strongly 

 hastate, about 3 mm. long. Three mental grooves. 



Ears much as in the celebe^isis-borneensis type, but somewhat 

 more blunt-tipped. 



Wing-structure quite primitive, i. e. no lengthening of III.^, 

 this phalanx being always less, and very often much less, than 1 ^ 

 the length of III.^ ; no shortening of the third metacarpal ; fourth 

 metacarpal slightly the longest (individually it may fall short of 

 the fifth by a fraction of a millimetre). This wing- structure is 

 perfectly like that of Bh. simjolex and its allies. 



Tail slightly longer than (individually equal to, or a trifle 

 shorter than) the lower leg. Plagiopatagium inserted on the 

 ankle, slightly above or below. 



Skull. General shape : the simjjlex-boi^neensis type, but consider- 

 ably smcdler, toith smaller teeth, and shorter tooth-roivs. The 

 orbital cavities (the confluent orbital and temporal fossse) are 

 shorter and narrower than in borneensis, the zygomatic arches, 

 therefore, less projecting laterally, making the zygomatic width of 

 the skull, as a rule, only equal to, or even a trifle smaller than, 

 the mastoid width. These peculiarities combined make, as a rule, 

 the skulls of the species of the lepidics-tj-pe rather easily distin- 

 guishable from those of the borneeQisis-type. — Arrangement of the 

 nasal swellings, essentially, as in borneensis. Palatal bridge, 

 on an average, somewhat less than ■^, but more than 1 the length 

 of the maxillar tooth-row. 



Dentition. Position of P3 (in, or external to, the tooth-row) 

 " vacillating." p^ invai-iably in the tooth-row. This dentition is 

 precisely as in simplex-borneensis. 



Species. Bh. lepidios, monticola, refulgens.
