Introduction. 



The following is a continuation of the work on 

 Notoryctes typhlops, of Avhich Part I, on the Nose and 

 Jacobson's Organ ; Part II, on the Blood-vessels ; and Part 

 III, on the Eye, have already been published [11, 12]. 



It has been thought well to make the record of the 

 anatomy of Notoryctes more complete by incorporating here 

 a fuller account of the skin and hairs, and also of the repro- 

 ductive organs and associated parts, than has previously been 

 given. 



Professor Baldwin Spencer has therefore kindly handed to 

 me the drawings and notes he had made in connection with 

 these structures ; for this, as also for access to his stock of 

 animals, I wish to record my indebtedness and thanks. 



As stated previously in another place no embryonic material 

 is forthcoming, so that no facts concerning the development 

 of these parts can be given.
