tlie absence of " transverse lines" from the membrane alon^r 

 the sides of the abilomen, and the presence of " reguhuly 

 ])arallel ridges at the base of the ear." The British IMuscuin 

 j)ossesses a specimen (skin, no. (JO. 5. 4. 13), received from 

 the India House Collection, whieh is in all probability the 

 actual individual referred to by Horsficld ; the peculiarities 

 emphasized by him arc partly due to bad preparation of tho 

 specimen and partly are quite individual. In 18G3 (/. s. c.) 

 Blyth ])roposed the name llorsJiclUi for the ?pecies described 

 but left unnamed by Ilorslicld. AVhen tiie late Dr. J. 

 Anderson (Cat. Mainm. lud. Mus. p. 21, 1881) registered as 

 " typos " of M. llorsfieldi two specimens obtained by 

 ]\Ir. Theobald in Tenasserim ho was undoubtedly in error, 

 lily til's M. Uorajieldi was, as already pointed out, based on 

 llorstield's " Meyadenna " from Continental India. 



2. Megaderma carimatce, Miller. 



1906. Mvgaderma carimatcB, Gerrit S. Miller, Jan., Proc. U.S. Nat. 

 Mas. xxxi. uo. 1181, p. 65. 



The species is known to us only from the published account. 

 'J'ype locality: Karimata Island. According to Miller, it 

 difters from M. spasma only in the smaller size and larger 

 ear.>J. The former character must bo dropped : Miller gives 

 as length of the forearm (five males and four females) 53'G- 

 58'G mm., as against 57-Gl mm. in M. spasma (seven females, 

 Malay Peninsula, /. e. M. s. trifoiium of the present paper) : 

 but, first. Miller has compared his M. carimatce with females 

 only of M. spasma, and females of this species average larger 

 than males ; second, we find in twenty-nine individuals of 

 M. s. trijulnim the forearm varying between 53 and 62 mm. 

 There remains the alleged greater length of the ears in 

 iV. carimatce : measured from the crown " 31*4-35 ram." 

 {Miller) against " 27-29 mm." [Miller] in M. spasma ; we 

 find that similar measurements for M. s. trifoiium range from 

 27-30 mm. (Malay specimens 28-29 mm.).
