MOLLUSC A 379 



(20) Attriadella westerlundiana Ancey. 



Auriculella westerlundiana Knc^y, Bull. Soc. Malac. France, vi. (1889), P- 218; 

 Sykes, P. Malac. Soc. London, in. p. 275, pi. xiii. fig. 21. 



Hab. Hawaii, Kona, and Waimea (Ancey) ; Kona at 3000 feet, and Olaa 

 (Perkins). 



Insufficiently known or erroneously recorded species. 



The following appear to be only manuscript names : jucunda Smith ; solida 

 Gulick ; solidissima ^vcix^ (confer Ann. Lye. New York, x. pp. 331 — 2). 



Bidimus pumicatus Mighels, P. Boston Soc. 11. p. 19. 



Hab. Oahu. 



Probably this is really an Auriculella ; I am totally unacquainted with it. 



Partula pusilla Gould, P. Boston Soc. 11. p. 197; U. S. Explor. Exped. Mollusca, 

 pi. VII. fig. 90. 



This species has been referred to Auriculella, and consequently a Hawaiian 

 habitat has been suggested for it ; it is really, however, a To)'nalellina and was 

 described from Metia [ = Mata]. 



Frickella Pfeiffer.

Frickella anioena Pfeiffer. 



Achatinella {Frickella) amoena Pfeiffer, P. Zool. Soc. London, 1855, p. 2, pi. xxx. 

 fig- 3- 



This aberrant species appears to be a link between Achatinella and Tornatellina. 

 The single young shell, found by Mr Perkins, does not quite agree with the type, as 

 the whorls are flatter, but 1 am unable to sever it specifically. 



Hab. Oahu, Konahuanui (Baldwin) ; Halemano (Perkins).
