46 MYDAUS MELTCEPS. 



the anterior half a good deal shorter, the hindmost upper 

 molar is stouter and of a relative larger size , the hind- 

 most lower molar is stronger and the penultimate lower 

 molar is a much more developed tooth : it measures 9 ram. 

 in the large Java-skull, 8 mm. in the smaller Borneo-skull, 

 and 10 mm. in the still much smaller Calamianes-skull ! 



The claws of the Calamianes-specimen are less developed 

 and do not attain the enormous size as in specimens from 

 other localities. 



In conclusion I do not know whether the Sumatra- 

 Mydaus differs from the Ja,\a.-Mydaus meliceps, I am in- 

 clined to believe that the Borneo- Mydaiis may perhaps 

 belong to an other, although to Mydaus meliceps closely 

 allied species, but it seems to me that the Calamianes- 

 Mydaus differs in so many points — in size, color, skull 

 and dentition — that it deserves to be separated under a 

 new specific title. I propose to call it Mydaus Schadenhergii 

 after its discoverer. 



The geographical range of the genus Mydaus is so far 

 as we at present know: Java, Sumatra, Borneo, Palawan ? 

 and the Calamianes-islands. 



Herpestes brachyurus Gray. 



Described in 1837, recorded in 1846 from the Malayan 

 Peninsula and in the Zoology of the Samarang in 1850 

 from Borneo, the first specimen of this species from Su- 

 matra reached Europe in 1 888 ; it had been collected by 

 Dr. Hagen in Siak and is since in our Museum (N. L. M. 

 1889, p. 23). In P. Z. S. L. 1889, p. 223, H. brachyurus 

 has been enumerated by Mr. Everett among the mammals 

 which are known to exist in the Palawan-group. Where a 

 specimen from the latter locality has been preserved for 

 control of that statement I do not know, but certainly 

 not in the British Museum , as Palawan is a locality that
