THE LONG-LEGGED POUCHED MICE. GENUS 
ANTECHINOMYS. 
Antechinomys, Krefft, Proc. Zool. Soc., 1866, p. 434. 
Body unspotted ; ears very large; tail very long and tufted; 
limbs much elongated, the lower portions of the legs and the 
hind feet being disproportionately long ; toes short and sub- 
equal; no first toe (hallux) to the hind foot; soles of fect 
without distinct pads, the greater portion of those of the hinder 
' pair being hairy. Number of teats unknown. Three pairs of 
premolar teeth in both jaws ; canine teeth very small. 
The special characteristics of this genus are the great elon- 
gation of the limbs, and the absence of the first toe of the hind 
foot. 
The one known species is a jumping terrestrial animal, 
bearing the same relationship to the Narrow-footed Pouched 
Mice as the Jumping Shrews of Africa present to the Tree- 
Shrews of India. Like its allies, it feeds exclusively on insects. 
Mr. Thomas remarks that the relationship of this genus to 
Sminthopsis is similar to that presented by the Jumping Mice 
({apalotis) of Australia to ordinary Mice (Jus); this salta- 
torial mode of progression having been doubtless developed
