The teeth with the essential characters of those of Sminthopsis. 

 Upper incisors small and delicate, cylindrical, not flattened; i.' 

 separated from the rest, but not markedly raked forwards. Canines 

 very small and short, scarcely projecting beyond the general 

 level of the tooth-series. Premolars evenly, but slightly, increasing 

 in size backwards. Lower incisors subequal. Canine very short, 

 about the same length as p.^; p.' and p.* about equal, slightly 

 shorter than p.' M.^ with a distinct antero-internal secondary cusp. 



MUk-dentition not known, but no doubt as in Sminlhopm. 



Habits. Terrestrial ; saltatory ; insectivorous. 



Range. That of the only species. 



This genus evidently bears the same relationship to Sminthopsis 

 that the Eodent Hapdlotis, also Australian, does to Mus, being 

 specialized in precisely the same manner for a saltatory method 

 of progression, a method apparently peculiarly favourable in the 

 sandy country inhabited both by Hapalotis and Antechinomya.

Jebboa Pouched Motoe, 



Size small, form very slender and graceful. Fur long, soft and 

 fine, composed almost whoUy of underfur. General colour pale 

 grizzled grey. Head grey, the bases of the hairs dark slate, their 

 tips pale fawn, the colour lighter on the cheeks, muzzle, and above 

 and behind the eyes, and darker on the crown, from which a 

 darker median patch passes backwards along the back of the neck ; 

 a large patch behind each «ar pale fawn, contrasting markedly with 

 the darker occiput. Ears very large, ovoid; laid forward they 

 reach to halfway between the muzzle and the anterior canthus of 

 the eye; covered nearly entirely with short, fine, fawn-coloured 

 hairs. Back-hairs very long and fine, slaty grey except at their 

 extreme tips, which are pale fawn; the few longer hairs black. 

 Chin white, chest and beUy grey at their bases, with broad white 

 tips ; change of colour on sides rather abrupt. Limbs coloured and 

 like the body only as far as the elbows and the middle of the tibiae ; 

 the remainder, with the hands and feet, pure white. Palms naked, 

 closely granulated all over, provided with a trefoil-shaped anterior 

 and a smaller posterior prominence, but without distinct trans-
