ON A SECOND COLLECTION OF MAMMALS FKOM 

 THE NATUNA ISLANDS. 



By OLDFIELD THOMAS and ERNST HARTERT. 



(See NoviTATEs ZooLOGiCAE, I. p. 052, and Novitates Zoologicae, II. p. 26.) 



ri"^HE present article deals with a large collection of Mammals, made liv Mr. Ernest 

 -L Hose on the islands of Bunguran and Puhi Laut, at the same time that the 

 birds were collected of which Hartert has given an account (antea, p. 466). 



The Bunguran mammals are of comparatively little interest, as they naturally 

 consist almost entirely of the si)ecies collected by Mr. Everett, and previously 

 described by us, but those ft-om P>ilu Laut are more valuable, and the first that 

 have ever come from there. They are mostly paler and smaller than their Bunguran 

 representatives, and it is to be regretted that the collection from Pulu Laut is not 

 larger. 



Species not. found by Mr. Everett are marked with an asterisk. 



1. Semnopithecus natunae Thos. & Hartt. 

 A series from Bunguran only. These monkeys are very constant in colour, all 

 agreeing with the description given by us, loc. eit., p. 652. A young specimen, killed 

 in August at 2000 feet on Mount Eanai and measuring about 270 mm., is inter- 

 mediate in colour between the new-born specimen described Xovitate.s Zoologicae, 

 I. p. 653, and the adult, the forehead and other parts which are white in the young 

 and black in the adult being grizzled greyish, from a mixtui'e of the two sorts of hairs. 



2. Macacus cynomolg'us (Schreb.). 

 A small series from Bunguran. 



3. Nycticebus tardigradus (L.). 

 A specimen from Bunguran, of a rather rufous colour, simihir to some of the 

 examples in the Briti.sh Museum. 



4. Galeopithecus volans L. 



Several specimens from Bunguran, of both grey and rufous \arieties. 



.'■>. Pteropus vampyrus L. 

 a, h. Pulu Panjang, Bunguran. 



6. Pteropus hypomelanus 'IVnun. 

 Many specimens. Pulu Pandak, Pulu Panjang, and Pulu Laut. 

 These specimens, as usual in this species, sliow a considerable amount of variation 

 in colour, but the diiferent forms all seem to pass into one another. 



7. Tupaia splendidula typica (iray. 

 n — (/. Four .sjiecimens, Mount Ranai, Bunguran, 

 These .specimens fully agree with those sent in the previous collection.
