the lower throat. Above this gorget there is another half-moon shaped one, also 

 well-marked but not so broad. On the sides of the throat there are thus four distinct 

 black stripes. The fur between these stripes is whitish, except the brownish white 

 shoulder stripe. Under parts of body brown, the hairs broadly tipped with greyish 

 white. Ears blackish brown, tipped with greyish white. Tail below like the under- 

 parts of the body and ringed with several greyish brown bands not continued round 

 the tail which is blackish brown above.

This species is fairly common in Borneo and has been recorded from several 

 localities on the great Island. 



In the Tijdschrift voor Natuurlijke Geschiedenis en Physiologie, 1838, p. 144, 

 Dr. S. Muller described a species under the name of Viverra boiei. lf this species 

 is different from the typical H. derbianus Gray I am at present unable to state on 

 account of the lack of material of tj^pical H. derbianus. If there are any differences 

 between the Bornean animal and the form inhabiting the Malay Peninsula the 

 former ought to be known as H. derbianus boiei Muller. The following description 

 is based upon the specimen collected by Mr. Lumholtz. 



General colour above påle cinnamon (Ridgway pl. 29) becoming more tavvny 

 along the sides of the body. On the back there are o broad transverse bands of 

 blackish brown, the middle one being the broadest. At the base of the tail a similar 

 blackish band. 



From the top of the rhinarium there is a blackish brown longitudinal stripe 

 running över the top of the head to about the ears, and this line is bordered on each 

 side by påle brownish white. Outside these stripes another blackish brown stripe is 

 running above the eyes to the bases of the ears. On the nape there are two brownish 

 black longitudinal stripes. Posterior of them two more or less broken transverse 

 lines; some distance in front of the first transverse band on the back two 

 distinct spöts of blackish brown. Base of tail like the back, becoming blackish 

 brown towards the tip. Lower surface of body tawny. Legs and feet similar, but 

 largely intermixed with greyish white hairs, most conspicuous on the inner sides. 

 Above the eyes a distinct whitish spöt. Chin and cheeks påle brownish white. Bases 

 of ears blackish brown, påle brownish white at tips. The skull is unfortunately 

 almost broken and only the following measurements could be taken. Length of 

 upper toothrow from front of canine to back of last molar: 40, i; width of palate 

 between inner edge of last molars: 19, o; length of lower toothrow from front of 

 canine to back of last molar: 44,6 mm.
