MUS RATTUS JALORBNSIS, BoNU 

 Ciroat Redang Island. 11 <? 7 ? . 

 East rerhentian Island. 23 (? 13 ? . 



Accept iug for the present Boiiliotes' name of Miis jalorensis as 

 applicable to all the white-bellied animals of the ratfus group occurr- 

 ing in the Malay Peninsula, I place these examples from tlie 

 Trengganu Ai-chipelago under the same title, and pending a thorough 

 examination and revision of the group, it may also cover the animals 

 inhabiting many of the adjacent Islands — i.e., Sibu, Jemor, the Laug- 

 kawis and Terutau — though certain small differences are perceptible 

 amongst all these. 



From dimensions it would appear that the GTreat Eedang animal is 

 the smaller of the two, but the series consists of nine adult indi- 

 viduals only against 30 from East Perhentian Island : 



Head 

 and body. 

 Kedang average ... ... 176.2 



Perhentian „ 181.3 



Redang maximum ... 183 



Perhentian ,, ... 197 



Eedang minimum ... 165 



Perhentian „ ... 172 



TRAGI'LUS RAVUS, Millek. 

 Great Eedang Island. 1 <? . 



The single example obtained does not appear to differ in any 

 respect from the mainland animal. Collector's external measurements : 

 head and body, 405 ; tail, 65 ; hind-foot, 105 ; ear, 32. Cranial 

 measurements : greatest length, 88 ; basal length, 76 ; zygomatic 

 breadth, 39 ; least interocular breadth 26. 



NOTES ON TWENTY-THREE SPECIMENS OF PTEBOPUS 

 HYPOMELANUS LEPIDUS. 

 By KNUD ANDERSEN. 

 The series of Pt. hypomelamis lepidus on which the following notes 

 are leased is, thus far, the largest ever Ijrought together for examina- 

 tion on one spot. A brief account of the individual variations 

 exhibited h\ this series, chiefly as regards the colours of the hir, may 

 therefore be of some interest to specialists.
