XI. — On a Further Collection of South African Slugs, loith a Chech- 

 list of Knoion Species. — By Walter E. Collinge, Lecturer on 

 Zoology and Comparative Anatomy in the University of Bir- 

 mingham. 



(Plate XIV.) 



For the facilities to examine the present interesting collection of 

 South African Slugs, I am indebted to the kindness of Mr. E. M. 

 Lightfoot, of the South African Museum. 



In a previous paper * I pointed out that probably many new 

 species awaited discovery, and the present collection made by Dr. F. 

 Purcell adds a further species to that interesting genus Apera, Heyn., 

 and also a new species of Oopelta. 



Mr. Lightfoot has very kindly sent me some notes relating to the 

 natural colours and variation of the different species, which are of 

 much value ; these I have incorporated in the present paper. 



Family LIMACID^E, Leach. 

 Gen. LIMAX, L. 



LiMAX MAXIMUS, L. 



All the specimens are immature, the largest measures 63 mm. and 

 the smallest 44 mm. in length. There are five specimens, and the 

 colouring and markings seem to be subject to very little variation. 

 Externally they remind one very much of some of the Italian forms. 

 I have little doubt but that this is subspecifically distinct from the 

 L. maximus, L. 



Hab. Table Mt., Newlands, F. Purcell and E. Lightfoot, 

 '6982.1- " Found under rocks some distance up Table Mt." (E. M. L. 

 in litt.).
