19. Helix (Ehytida) capillacea, Pfeiffer. 



2 New South Wales; ex c. Dr. J. C. Cox. 



20. Helix (Rhytida?) inaequalis, Pfeiffer. 



2 New Caledonia ; ex c. A. Morelet, Esq. 



1 do Bot see how Messrs. Crosse and Fischer can make this 

 species the type of Bhytida, when its author states that the type 

 of the latter is the New Zealand H. greenivoocli. When proved 

 that they belong to different genera, the New Caledonian group 

 must receive a new name : the same applies to Rotula. Prof. 

 Semper cannot now make its type N. caelatura ; the type is and 

 must remain N. detect a, as correctly asserted by Dr. Stoliczka ; 

 the two belong to different sub-generic sections. 



21. Helix (Ehytida?) dictyodes, Pfeiffer.

From the shell, I should have classed this form near Sesara.
