The kidney is characteristic in being long and relatively very broad, and in 

 having its distal extremity curved. 



The association o£ characters above enumerated is not found in any other 

 Zonitoid genus the author is familiar with, and the vs^orks of Godwin-Austen, 

 Semper, &c. have been searched in vain. Clearly allied to Rliysota, and 

 possibly AriopJianta, it nevertheless appears to be generically distinct. 



Veronicella hovarum, n. sp. {v. antea, no. 24). 



The radula (fig. 4) has the formula : — 



? 17. ?34. 1. ?34. ?17. =105. 



The teeth are closely crowded and the base of the central tooth is obscured 

 by the internal angles of the first laterals. The rows of teeth are disposed in 

 an undulating pattern, each half-row slanting forward from its central tooth 

 until about the fortieth tooth, and then commencing a backward slant. 



The jaw {cf. fig 5) is remarkably wide. It exhibits four or five broad 

 overlapping plates at each extremity, while the median plates are more 

 narrow and fibrous.

The centi-al tooth has a peculiar tendency towards asymmetry, the lateral 

 cusps shown in the drawing being frequently disposed at different heights 

 from the base.
