my paper on British Apodemus (Ann. & Man^. Nat. Hist., 

 July 1914). The whole of the last paragraph on p. 130 

 should be deleted. The young specimen referred to is a 

 house-mouse, the skin figured by accident as that of a young 

 Apodemus in the first list (P. Z. S. 1913, p. 836). Later on, 

 through misreading a label, I associated the skin with the 

 skull of a young Apodemus. 



LIU. — The Ilolotype of Nymplion pracilipes, Miers {Pi/cno- 

 gonida). By W. T. Calman, D.Sc. 



(Publislied by permission of the Trustees of the British Museum,') 



Although several writers have discussed Nymphon gracilipes^ 

 Miers, since its first description in 1875, no one ap])ears to 

 have re-exainined the holotype, and a good deal of unneces- 

 sary confusion lias therefore gathered round tiie species. As 

 a result of comparison of the holotype with other specimens 

 ill the British Museum collection, the following synonymy is 

 proposed : — • 



JSli/mphon gracilipes, Miers.
