398 Mr. G. Dollman on 



beds of spruits. When smoking out one of these nests in a 

 fallen tree once, rather an extraordinary thing happened. 

 For a long time there was no signs of any mouse, then 

 suddenly the female came tumbling out on to the ground 

 with four new-born hairless young ones apparently hanging on 

 to her mamma; she may have had one in her mouth, but three 

 were certainly hanging on to the mammae."

" These mice were caught on the edge of the marshes, 

 where they were living in the burrows of Tatera brantsi per- 

 pallida ; they were rather uncommon apparently, as they were 

 only caught in the proportion of one to 20 Tatera. It is 

 remarkable that both these specimens of Epimys had been 

 attacked by some parasitic fly, probably Cordylobia anthro- 

 pophagus or some near species : the maggots were in both 

 cases in the scrotum, which was much enlarged and full of 

 pus ; in one case the testes were diseased and one almost 

 entirely sloughed away. The mice were otherwise in good 

 condition and fat. No specimens of Tatera were found 

 infected. It is possible that, owing to some habit, this mouse 

 is peculiarly subject to these parasitic flies, which, destroying 

 the reproductive organs, are exterminating the species in the 

 locality."

Although this series is rather paler in colour than 

 de Win ton's type, there seems to be no reason why these 

 Kalahari and Ngamiland specimens should be considered as 

 other than true S. anderssoni.
