and arrangement of the foot pads. Hitherto this species has been 

 included in ConiVuriis, Ogil., of wliich the type is C. conditor, but 

 a reference to the type species shows that it has not the pecu- 

 liarity here sought to be emphasised ; it would therefore appear 

 that there is no alternative but to create a new genus for the 

 species in question. How many more of the species now ranked 

 under Conilurus will be required to follow C. longicaitdatiis into 

 the new genus, is not yet decided, but C. apicalis and C. pedun- 

 i:ulaius will certainly not do so.

Gould's figure is an excellent representation of this animal and 

 there is little to add to the color-description ; the brown on the 

 tail is confined to the basal half of the upper surface, and the 

 hairs towards the tip are considerably lengthened, forming a 

 pencil of white. Gould described the tail as being thinly clothed, 

 but it is probable that the tail of his single example had been 

 iiomewhat denuded of hair. The mark on the fore feet mentioned 

 and illustrated is exhibited by our specimen, the hind feet also 

 .show a dark mark. The fur of the under parts is white at the 

 l>ase, that of the coloured portions dark grey. The hind limbs 

 are not specially lengthened, and I would therefore consider that 

 the method of progression was rat- and not jerboa-like. 



Tail-scales average nine to the centimetre. Mammae, 0-2 = 4. 



Skull somewhat elongate without marked ridges, preorbital 

 processes large ; anterior palatina foramina wide, front edge of 

 anterior zygoma root quite straight and perpendicular, upper 

 iingle gently rounded ; coronoid feebly developed and the incisor 

 capsule very low, scarcely raised in fact. 



This incisor capsule necessarily absent in so many types, yet 

 forming such a conspicuous feature in the inaudible of Myomorphic 

 and other Rodents, is subject to considerable variation, but 

 whether it is a character worthy of special note I cannot yet say : 

 the descriptive term is adopted from Merriam's^ Pocket Gophers.
