other known that it evidently represents a distinct species. I have, 

 liowever, not been able to describe it before, owing to a doubt as to 

 what sexual variation there might be in the genus and the fact that all 

 our adult skulls appeared to be those of females. Now, however, 

 thanks to the kindness of Mr. H. ('. ilnbinson, 1 have before me a line 

 male skull from Bukit (fautang. Perak, and am thus able to make 

 a proper comparison wiUi the Siaiiiese animal. 'I'liis latter maj' be 

 called 



Arctictis uaikd.neui, .^p. n. 



Size conspicuously greater than in the other species. Skull 

 broader, more vaulted. Nasals very broad, parallel-sided to the point 

 where they join the frontals laterall}', instead of eveidj- narrowing from 

 front to back. Frontal region broad, much swollen upwards and 

 laterall3% then abruptlj' narrowed at the fronto-parietal suture. 

 Sagittal and lambdoid crests greatly developed. I'osterior palate 

 broad, much produced backwards. Bulkc narrow, far overlapped by 

 the heavy paroccipital processes. Teeth much worn down in the t3'pe, 

 their pro]iortions appirentl}' about as in the Pei'ak skull. 



Dimensions of the type (those of the JVrak male in brackets): — 



Greatest length 153 mm. (136) ; condylo-basal length 152 

 (136); zygomatic breadth 98 (81-5); nasals, mesial length 28 (21), 

 breadth at middle 19 (12); interorbital breadth 41 (33); tip to tip 

 of postorbital processes 59 (47"5) ; breadth innnediately behind the 

 latter 51*5 (-10); breadth at fronto-parietal suture 41 (39); greatest 

 posterior breadth on ridges 73'5 (59) ; height of crown from posterior 

 palate 545 (47) ; palatal length 81-5 (73) ; breadth of postei-ior palate

This binturong diSers so immensely in size from the ordinarj' 

 Arctictis that no detailed comparison is needed in describing it as new. 

 It aflfords a curious paralled to the giant Arctoni/x of the same region— 

 A. dictator — discovered by Mr. Robinson, which was also obtained by 

 Mr. Gairdner at Sai Yoke. 



I have much pleasure in coiniecting this fine species with the 

 name of its discoverer, who has been making great afibrts to improve 

 our knowledge of the Siamese mammal fauna. It is to be hoped that 

 he maj' presently be able to obtain a complete specimen of Arctictis 

 fjairdneri.
