slender, being slightly curved and bearing ventrally at the apex two pairs of 

 bristles (Fig. 7, viii. st.). The eighth tergite bears eight bristles above and two 

 below. The process P of the clasper is narrow, being almost pointed (Fig. 6). 

 The finger is broader at the apex than in S. sciurorum. The bristles are also 

 different. The inner arm of the ninth steruite is strongly curved. The bristles on 

 the central widening of the horizontal arm are numerous.

FURTHER NOTES ON MACROPUS 3IAGNUS. 

 By THE HON. WALTER ROTHSCHILD, Ph.D. 



WHEN I described, from a living animal in my collection, what I believed 

 to be Macropus magnus of Owen (cf. Noc. Zool. xii. p. 509, 1905), I 

 stated that until the death of the animal we could not be certain if it was really 

 M. magnus. This reservation has turned out to be very wise. In the early part 

 of this year I received an adult pair of kangaroos much resembling large Macropus 

 ruj'us, but the female was of the same colour as the male, both being of a bright 

 reddish buff with blue-grey faces, and the undersides much paler whitish buff. 

 The fur is short and woolly, as in M. rufus, but even softer and more silky to 

 the touch. These animals, like the previously mentioned supposed M. magnus, 

 were sent from some portion of Northern or North- Western Australia. When this 

 winter began all three unfortunately died, and the examination of the skulls, 

 now that the animals have been prepared, has at last cleared up the long- 

 standing mystery of Macropus magnus. The formerly described animal turns 

 out to be a new species, while the pair received afterwards belong to the true 

 M. magnus. In the male skull the palatal foramina, owing to captivity, have 

 become abnormal, the left one being tilled up by an osseous thickened mass, 

 while the right one is divided in two by an osseous septum ; but the high and 

 sharply developed cusps of the molars are more strongly developed than in the 

 type, and the other distinctive characters separating M. magnus from M.- rufus 

 are very conspicuous. 



I have now received a second specimen of the kangaroo I formerly wrongly 

 identified with M. magnus, and, as the skull proves it to be distinct, I have much 

 pleasure in namiug it after Mr. Karl Hagenbeck, from whom I received the pair 

 of true M. magnus, as follows :
