66 MACKOPOBIDJS. 



This animal is by far the most strikingly coloured of the family, 

 but the contrasts are of so glaring a nature as to prevent its being 

 pleasing to the eye. Its skull is readily distinguishable from those 

 of the other species by the inflation of the muzzle and forehead, 

 although this inflation cannot compare in extent with that found in 

 Macropus antilopinus, being more like the moderate inflation present 

 in M. giganteiis (see supra, p. 17).

* Said to be distinguished " from all other species by its remarkably long 

 and bushy tail, which is about a foot longer than that of any other Rook- 

 Wallaby." I can only presume that Mr. JKrefft had not a full-grown male 

 specimen of F. penicillata with a perfect tail available, as the tail of this species 

 often attains a length of 24 inches, so that the 27 inches of the specimen described 

 by Mr. Krefft is by no means beyond what might be expected occasionally to 

 occur.
