//. schnelderi differs from its nearest geographieal relation, 

 H. labuanensis, Tomes (^), in the following particulars: — 



(1) In //. labuaiiensis the tip of p^ (anterior lower premolar) is 

 about level with the middle of the principal cusp of p^ (posterior 

 lower premolar); in H. schnelde^ù ]ì., in very much reduced in 

 size, its tip only a little higher than th(^ cingula of the canine and 

 Pj , not, i)y far, reaching the middh- of the cusj) of }»4. In H. la- 

 buanensis the length (antero-])osterior extent, labial as])ect) of 

 p^, at base is not nuich smaller 1han the length of p^ at base; in 

 H. Schneider i the length of p^ is scarcely half the length of p^. 

 In H. labuanensis \^., in cross seclion at base is — --^, in//. 

 Schneider i -7-7^-- of p^. In short: p^, is in //. sclineideri very 

 nuich smaller tlian in H. labuanensis, and this is, in fact, the 

 most convenient character for a ready discrimination of the two 

 species. 



(2) To the reduction in size of })., corresponds a reduction in 

 size of p2 (anterior upper ])remolar). In //. labuanensis p^ is 

 small, but easily observable; in H. schneideri it is exceedingly 

 small (as a small dot), situated (juite on the external side of the 

 maxillary i)one, very difficultly observal)le (scarcely at all without 

 a lens), and occasionally wanting ; in the type of the species it 

 is present on one side cmly, in the two specimens collected by 

 Dohrn on both sides. 



(3) The nasal swellings in H. schneideri are a trifle broader 

 than in R. labuanensis: anteorbital width in the former species 

 Ì5.8 mm., in the latter 5 — 5. Ti mm. 



(') H. galcyitus, auct. plurim.; but the type specimen of H. gikriius (in the 

 British Museum) seems to me quite a different bat; I therefore, for the present, use 

 the name H. labuanensis. Tomes, for tlie small Bornean species witli a frontal sac 

 and two supplementary leaflets. All the small Kastern species of Hippostdenis liadly 

 need a careful revision.
