54 ; c; greatest width of braincase: 35. o; least interorbital width: 13.?; least postorbital 

 width: 21,2; length of nasals mesially: 18,2; breadth of combined nasals at anterior 

 extremity: lO.o; median palatal length: 33,0; greatest length of bulla?: 20,6; greatest 

 breadth of bulla?: 12.3; maxillary toothrow (alveoli) : 25,o mm. 



23. Pardofelis marmorata Martin. 



Proc. Zool. Soc. London 1836, p. 107. 

 $ Poeroeok Tjahoe, Central Borneo, Noy. 1915. 



Of the Marbled Cat which inhabits the Himalayas, Sikkim, Assam, Burma, the 

 Malay Peninsula, Sumatra, Borneo and Java, Mr. Lumholtz only obtained a single 

 specimen. This specimen, though fullgrovvn, is apparently not very old as the orbital 

 rings are not closed by bone all round. The Marbled Cat seems to be arboreal in 

 its habits and is said to be more common in low-lying country where it frequents 

 the forest clearings. 



Skull measurements : Greatest length of skull: 79. o; condylobasal length: 70.8; 

 basicranial length: 65. o; occipitonasal length: 75, i; zygomatic width: 56,3; greatest 

 width of braincase: 41. c; least interorbital width: 12.3; least postorbital width : 32, 0; 

 length of nasals mesially: 13,?; breadth of combined nasals at anterior extremity: 

 9,5; median palatal length: 27, i; length of upper toothrow from front of canine to 

 back of last molar: 25,o; length of lower toothrow from front of canine to back of 

 last molar: 27,o; length of bulla?: 18, o; breadth between bulla? at anterior extremity: 

 6,9 mm. 



24. Petaurista petaurista lumholtzi subsp. n. 



Type: Adult (skin and skull). Collected at Poeroek Tjahoe, Central Borneo, 

 Nov. 1915. 



In the collection there is only a single specimen of a Great Flying Squirrel, but 

 I have been compelled to describe it as a nevv subspecies, as it differs in several 

 particulars from the other Bornean form viz. P. petaurista rajah 1 Thos. This latter 

 form is being described by Thomas (Ann. Mag. Nat. Hist., Ser. 8, vol. I, 1908, p. 

 251) in the follovving words: »General colour almost as light as in melanotus (from 

 the Malay Peninsula) but darkened by blackish tips to the dorsal hairs so that the 

 general colour is intermediate between that of melanotus' and marchio (from Sumatra). 

 Head like body. Dark orbital rings at a maximum. Ears apparently shorter than 

 in the other forms and less narrow; their backs heavily tufted with deep black hairs, 

 which form a conspicuous black patch on each side. Hands and feet wholly dark, 

 the rufous not trepassing on to the metapodials. » 



The description of P. p. lumholtzi may be as follows. 



General colour deep ferruginuous bay, though much lighter on the posterior half 

 of the body. Head like the anterior part, though slightly darker on account of the 



1 Type Iocality: Mount Dulit, Baram, Borneo (2000 ft.). 



2 Type Iocality: Malay Peninsula.
