HORN EXPEDITION—MAMMALIA. 
Since the return of the expedition I have been able, tlirough the kindness of 
Mr. Byrne, to secure three more specimens, two of them fortunately being females. 
The measurements of the five specimens in my possession are as follows :—

Messrs. Thomas,* T.ydekker, | and Ogilbyt state that the number of teats is 
unknown. Kreftt§ says : — “ The female has no pouch, and is provided with eight 
mammie.” In both of specimens d and of which the dimensions are given abo\'e, 
there are six mammre arranged in a circle. There is no trace of a pouch, no folds 
of any kind being distinguishable, and the whole of the mammary area is thickly 
covered with hairs. Judging from the dimensions the animals are mature, so that 
probably the teats are only largely developed during'the breeding season. 
It does not, however, follow that because the number of teats in the two 
females above described is six, that therefore Mr. Krefft was wrong in stating 
that eight are present, as, judging from the variability previously described in the 
cases of Phas. cristicauda and S. crassicaudata, the number of teats is evidently 
subject to variation within the limits of a species.
