DESCRIPTION OF A NEW SPECIES OF ONCHIDIUM 

 FROM SOUTH AFRICA. 



By WALTER E. COLLI NGE. 

 The only species of Onchidmni. at present known from South Africa, 

 is the U. pei'oni of Cuvier. 



In November 1900, Mr. Henry C. Burnup very kindly sent me 

 two examples of a small species, which upon examination prove to 

 belong to a new species. It gives me much pleasure to name this 

 addition to the South African fauna after Mr. Burnup, as a mark of 

 appreciation of the valuable assistance he has at all times so willingly 

 rendered me, in connection with my studies on the slug fauna of 

 South Africa.
