288 Mr. E. Schwarz on a Kangaroo 



XXXVI. — On a Kangaroo and a new Pahn-Civet in the 

 British Museum. By Eenst Schwarz. 



Two years ago ('Annals,' ser. 8, vol. vii. p. 609, 1911) 

 Mr. Thomas described a Wallaroo from McClintock Range, 

 Kimberley Gold Field, Far North of Western Australia. In 

 his description he expressed some doubts as to the constancy 

 of the cranial characters used by me to separate the different 

 local races of M. robustus. I have recently had an oppor- 

 tunity of examining the type o£ Macropus robustus bracteator, 

 and by the kind permission of Mr. Thomas I am enabled to 

 give the following supplementary description of the skull in 

 a form closely resembling the diagnoses in my paper in 

 ' Novitates Zoologicse,' vol. xvii. (1910). 



Macropus robustus bracteator, Thomas. 



Skull. Basifacial axis short as compared to basicranial 

 axis. Nasal cavity strongly inflated laterally almost as 

 much as in M. r. rubens, but slightly less (especially when 

 viewed from the palate). Nasals very convex in both 

 directions, as already shown by Mr. Thomas, long, broad, 

 and almost parallel-sided. Processus infrazygomaticus nar- 

 row and strongly twisted. Zygoma as in M. r. woodwardi. 

 Opening of lacrymal canal in lacrymal bone. Foramina 

 incisiva short. Anterior portion of palate exactly as in 

 M. r. woodwardi, its margins regularly converging ante- 

 riorly, and not constricted in front as in M. r. rubens, its 

 least breadth about half the length of diastema. Profile of 

 skull strongly and regularly convex, its highest point in the 

 frontal region. 



Basicranial axis 47 mm.; basifacial axis 120; facial 

 index 255. 



The skull of this kangaroo is most like that of M. r. 

 rubens. As in that form, it has a low facial index and the 

 inflated nasal cavity, which, however, is slightly less 

 marked, so as to be somewhat intermediate between rubens 

 and woodwardi. The shape of the nasals and palate are 

 more as in woodwardi. 



In the local races of Macropus robustus the facial index 

 seems to be very constant, whereas in M. rufus and M. gigan- 

 teus it is extremely variable.

 Museum together with Mr. Wroughton, the specimens from
