Amastra H. and A. Adams. 



Amastra H. and A. Adams, Genera of Recent Mollusca, ii. p. 137. 



Type : the group of A. magna Ad. 



This large genus may for convenience be subdivided into groups somewhat in the 

 following manner ; perhaps the large first section might be more broken up, though I 

 think no sectional name will prove necessary. 



subgen. Amastra (s. str.). 



(i) Amastra affinis Newcomb. 



Achatinella affinis Newcomb, P. Zool. Soc. London, 1853 [1854], p. 142, pi. xxiii.

 Achatinella [Laminella) goniostoma Pfeiffer, P. Zool. Soc. London, 1855, p. 203. 



Amastra rtistica Gulick, P. Zool. Soc. London, 1873, p. 84, pi. x. fig. 17. 



Dr Hartman has suggested that A. riistica may equal A. variegata Pfr., an Oahu 



species. 



Hab. E. Maui, Kula (Newcomb, Gulick). 



(2) Amastra albolabris Newcomb. 



Achatinella albolabris Newcomb, P. Zool. Soc. London, 1853 [1854], p. 149, 



pi. XXIV. fig. 56. 

 Achatinella nucleola Reeve, Conch. Icon. Achatinella, sp. 39 \_non Gould]. 



One young specimen I refer to this species. See a note under A. subrostrata 

 Pfr. 



Hab. Oahu, Waianae Mts. (Newcomb, Perkins) ; Kapalama and Kalihi (Baldwin). 



(3) Amastra amicta Smith. 



Amasti-a amicta Smith, P. Zool. Soc. London, 1873, p. 86, pi. x. fig. 20. 

 Dr Hartman notes that this species "may (t(\\x-e\ petricola" ; it appears to me quite 

 distinct. 



Hab. Hawaiian Islands (Smith).
