Postscript, March 22, 1877. 

 Since the publication of an abstract of the foregoing paper in ' Nature ' for July 20. 

 1876, I have been enabled to compare the undermentioned skulls and figures of Suidce, 

 and to consult the undermentioned volumes and memoirs which had not previously been 

 accessible to me. I have also been favoured with valuable information by the letters 

 of a number of scientific correspondents named below. The information thus gained, in 

 addition to that upon which my paper was based, has been in the main confirmatory of 

 the views I had come to independently of it ; the very important fact, however, that the 

 young of Sus celebensis are striped, as communicated to me by Dr. A. B. Meyer, of the 

 Royal Zoological Museum at Dresden, is directly contradictory of the suggestion which 

 I threw out at p. 267, as is also the fact published by him as to the striping of the young 

 of the nearly allied S. verrucosus directly contradictory of the statement of Muller and 

 Schlegel given above, p. 266.
