species, but they may well represent independent developments, 

 especially since they also superficially resemble Pupillidae, to 

 which they are not at all related. Thus the tendency of modern 

 research will probably be to emphasize rather than diminish the 

 separateness of the Ethiopian fauna. 



It is rather a shock, at first, to see the African slugs hereto- 

 fore called Veronicella or Vaginula referred to L&vicaulis and 

 Pleuroprocta, names proposed several years ago by Simroth. It 

 can hardly be doubted, however, that the VeronicellidaB must 

 be held to include a number of genera, in spite of the great ex- 

 ternal similarity. Dr. Pilsbry is in error, I think, in calling 

 the family Vaginulidse, on the stated ground that the type of 

 Veronicella has not been rediscovered. As a matter of fact the 

 actual specimen described by Blainville is still to be seen in the 

 British Museum, as was explained in Conchologist, 1893, pp. 

 43-44. It was collected by Sloane in Jamaica, and is properly 

 called Veronicella sloanii (Cuvier).
