CHRYSOPTERON BARTELSII. 77 
Lateron Mr. Oldfield Thomas has described some new 
Kerivoula-species; as to the lower incisors he remarked: 
Smithii: first and second lower incisors trilobate, outer 
ones unicuspidate, 
javana: the teeth are quite similar to those of K. papuensis 
(therefore lower incisors trilobate, see above), 
Harrisoni: no history, 
pusilla: outer lower incisors tricuspid and longer (hori- 
_ zontally) than either of the two middle ones, 
Whiteheadi: apparently as in Hardwickit. 
Finally Mr. Miller described a Kerivoula-species, viz. : 
minuta: two lower incisors trifid and each considerably 
smaller than the unicuspid outer incisor. 
In the Proc. Biol. Soc. Washington, 1905, p. 229, Mr. 
Miller described a new bat from Sumatra, the type-species 
of a new genus, allied to Kerivoula, viz. Phoniscus atrox; 
Phoniscus and Kerivoula are the two genera which represent 
the subfamily Kerivoulinae (cf. Miller, the families and genera 
of bats, 1907, p. 232), which he distinguishes as follows: 
Kerivoula: upper canine normal; middle lower incisor 
with three cusps, 
Phoniscus: upper canine with shaft elongated and late- 
rally compressed; middle lower incisor with four cusps. 
To the true Kerivoula-genus, perhaps constantly with 
three-cuspidate anterior and middle lower incisors, appa- 
rently belong: Hardwickii, picta, papillosa, papuensis, Jagori, 
Smithii, javana, Whiteheadi, pusilla and minuta; as to 
pellucida however, with four-cusped anterior and three-cusped 
middle lower incisors, I only can suggest that it may 
belong again to another genus, a question however better to 
settle by the study of the type-specimen in the Zool. Soc. 
Coll. (Dobson, Catalogue, 1878, p. 338); perhaps it may 
turn out to be a Phoniscus? We know nothing of 
the lower incisors of brunnea, africana, aerosa, lanosa and 
Harrisoni.
