856 ROBERT COLLET, 



of the molars were resolved into small Single cylindrical teeth, 2 or 3 

 for each molar, corresponding with the number of the alveoli. Thus 

 in the upper jaw, instead of the right m\ there were 3 such small 

 teeth present; in the lower jaw the right m^ and m^, and the left 

 m^ and m'^ were resolved each into two such teeth. 



Another specimen (G) has in the upper jaw the leftp^ rudimen- 

 tary, but the teeth are otherwise normal. 



In two of the skulls the cavity in the intermaxillary, which is 

 filled by the lower canine, is so deep on the one side, that the jaw is 

 completely penetrated. 



The Perforation of the palatine bones is incomplete, and forms 

 no Single large foramen, but several irregulär ones. 



In some, probably females, the zygomatic arch is less prominent 

 than in the others.

D. geoffroyi appears to be the commonest species in Northern 

 Queensland. Like the others, it is greatly troubled with vermin, and 

 the für is therefore almost always more or less defective in specimens 

 obtained in the summer. 



In the specimens which have been brought home, the spots are 

 spread over the whole body, except on the tail, which, at its root, 

 has the same colour as that of the back, whilst the remaining |"'^ (in 

 the young one the remaining 1"^') is black. Thehead has only a few 

 spots on the forehead. The tail is somewhat bushy ; the hairs in the 

 young are specially long (length 40—45 mm). From the back of the 

 carpus some long and stiff hairs project, which resemble vibrissae, and 

 which are directed upwards and backwards. 



The thumb of the bind foot is short, and the joining membrane 

 extends almost out to the end of the outermost phalanx. By remov- 

 ing the skin, its dimensions in the two individuals could be seen to 

 be the following: — AB 



Sole of the bind foot (to tip of the claw) . . 58 mm 68 mm 



The outer phalanx of the thumb 2 mm 2,5 mm 



The inner phalanx of the thumb 5 mm 7 mm
