It is evident that M. stigmaticus and M. wilcoxi only form 

 respectively the tropical and non-tropical representatives of one and 

 the same original species, and wiU. nearly ceitainly have in time to 

 be united altogether, or be merely separated under varietal names. 

 As is usual in such oases, the northern form is shorter-haired and 

 more brilliantly coloured than the southern, the external distinc- 

 tions being exactly those that separate the t5'pioal M. ualabatus of 

 the south from M. ualabatus var. apiialis of Queensland. In that 

 case, however, the skulls were absolutely identical, but in the 

 present one the solitary representative available of the northern 

 form presents certain cranial and dental differenees from the 

 southern; and therefore, although believing that intermediate 

 specimens wiU probably be foufld, I yet hesitate definitely to place 

 the two together without seeiiig furdier material. Externally, the 

 specimen described by Mr. De Vis as H. temporalis would seem to 

 be fairly intermediate, but lio description is given of its teeth, and 

 therefore, chiefly on account of its locality, I consider it for the 

 present as a synonym of M. wilcoxi rather than of M. stigmatieus.

* The proper spelling of the speoiflo name of this species is somewhat 

 doubtful. The author of the " Beize aver Moskovie door Perzie en Indie " 

 nearly invariably spelt his name De Bruyn, which was altered in the French 

 ' and English editions of his work into Le Brun, on which Schreber formed the 

 name of the animal. In another earlier work by the same author, however, 

 the "Eeizen doorde vermaadste Deelen van Klein Asia, &o." (4to, Delft, 1698), 

 Bruyn, Bruin, and Brun all occur on one single page of the Introduction, the 

 last in the very form needed for a specific name, viz. "Oornelii Brunii," 

 as the Latin genitive of the author's name. I liave therefore used this, the 

 oldest and best known form, instead of the corrected one " bruynii " or " bruinii," 

 as used by one or two later authors.
