with Nesopupa griqualandica (Mel v. and Pons. ). 1 The new form 

 is ovate, of about the size of the other species, which it resembles 

 in sculpture and in the lamellae of the parietal wall and colu- 

 mella. The two palatal plicae are subequal, the upper emerg- 

 ing to the lip, the lower one also long, reaching to the inner 

 edge of the peristome. There is a very small nodule on the 

 base of the columella. In griqualandica the lower palatal plica 

 is short and very deeply immersed and there is a distinct though 

 small basal plica within the base, in front of the lower palatal 

 plica. In griqualandica there is a deep sulcus outside, over the 

 upper palatal plica, and a flattening or short groove over the 

 lower palatal; but in farquhari the sulcus is far less impressed 

 except quite close to the lip. The color is reddish brown. 

 Length 1.65, diam. 0.9 mm. 



Mr. Burnup's figure 9, in Melvill and Ponsonby's Revision, 2 

 may perhaps represent this species, while their description in 

 the same paper appears to comprise both griqualandica and 

 farquhari, though chiefly relating to the former. Their pi. I, 

 figs. 8 and 10 represent griqualandica. The new form is named 

 in honor of one of the most successful South-African collectors. 

 It will be figured in the Manual of Conchology.

 expanded and broadly rounded, anterior margin wider and much 

 more curved than the posterior; apex very excentric, depressed 

 and decidedly turned toward the right side, bluntly rounded,
