length. Til other species the female averages markedly- 

 larger than the male, but here we have the smallest specimen 

 of the female sex. 



With regard to G. undatus, of which the type skull has been 

 courteously lent me by the authorities of the Munich Museum, 

 I find that it cannot be referred to G. variec/atus, as it is still 

 larger, being the largest Galeopterus skull on record, with a 

 condylo-basal length of no less than 82*5 mm. Its exact 

 locality remains to be discovered. 



Then with regard to the smaller smaller-toothed iMalayan 

 and Bornean forms, I am still unable to find any difference 

 between the latter and a specimen from the Natuna Islands, 

 representing G. natunce, Mill. Possibly G. gracilis, Mill,, 

 from Sirhassen will also prove to be the same. 



But the additional material from the Malay Peninsula 

 indicates that the form found there is constantly larger, and 

 since no name appears to be applicable to it, I would suggest 

 that of 



Galeopterus peninsulce, sp. n. 



General colour in tne g.^/ phase pale, as in Sumatran and 

 Bornean specimens, decidedly paler than in G. vnriegatas. 



Skull, while smaller than in G. undatus, variegatus, and 

 temminchii, averaging decidedly larger than in the Bornean 

 and Natuna forms, and with the same marked sexual 

 diff'erence in favour of the female. 



Dimensions of the male (measured in flesh) .- — 



Head and body 345 mm. ; tail 271 ; hind foot Qb -, ear 21. 

 The measurements of the typical female were not taken.

On extracting the skull of the type specimen of this species, 

 from Java, I find that it is by no means quite like those in
