ON A NEW AUSTRALIAN MAMMAL. 351 



especially about the occipital region, but from a cursory examina- 

 tion of the recently skinned body I can note the following points, 

 with I believe accuracy. Cranium relatively large. No bony 

 orbits. Zygomatic arches present. Well developed shoulder 

 girdles witli slender clavicles. Pectoral muscles large. Pelvis 

 large and strong with a rather wide symphysis, but no epipubic 

 bones either actual or rudimentary. Ribs fourteen. Angle of 

 lower jaw markedly inflected. 



The teeth are peculiar, and require a more extended description 

 than I can give at present, but the formula appears to be 



^ ^ " V p- 1 m 4y' 



this, however, may require some modification as just posterior and 

 external to the prtemolar (or first molar) of the right ramus of 

 the mandible, there is a small rudimentary conical tooth which is 

 not to be found on the opposite side, or at corresponding positions 

 in the maxilla. 



I cannot help being struck with the resemblance both of the 

 lower jaw, and of the general characters of the teeth, to figures 

 of the jaws of Amphitherium, as figured in various osteological 

 works.
