Hab. Mayotfce {ex coll. Emile Exulel). 



This species is more elongate than most of the forms of Edentu- 

 Una and bears a general resemblance to Ehna svrinhoei of II. Adams. 



Eig. 2. 



Ennea {Edentula) longula. 



The outer lip, however, is not deeply sinuated as in that section of 

 the genus Ennea.

(Plate LX.) 



The collections, of which the following is an account, were made 

 by Mr. E. Crawshay and Mr. A. Whyte respectively ; the first 

 principally at Lake Mweru in 1891 and 1892, the second at Zomba 

 between July 1892 and January 1893. Of the two series the 

 former is in by far the better condition, and the latter considerably 

 more numerous both in species and individuals. So many of the 

 species in the two series are identical that I have thought it better 

 to combine them in one paper : together they represent no less 

 than 216 species, the majority of which belong to the South 

 African fauna. Thirty-one species are described as new to 

 science.
