Amastra H. and A. Adams, Genera of Recent Mollusca, . 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.). 
(1) <Amastra affinis Newcomb. 
Achatinella affinis Newcomb, P. Zool. Soc. London, 1853 [1854], p. 142, pl. xxi. 
fee a5: 
Achatinella (Laminella) goniostoma Pfeiffer, P. Zool. Soc. London, 1855, p. 203. 
Amastra rustica Gulick, P. Zool. Soc. London, 1873, p. 84, pl. x. fig. 17. 
Dr Hartman has suggested that 4. rustzca may equal A. variegata Pfr., an Oahu 
species. 
Has. E. Maui, Kula (Newcomb, Gulick). 
(2) Amastra albolabris Newcomb. 
Achatinella albolabris Newcomb, P. Zool. Soc. London, 1853 [1854], p. 149, 
pl. xxiv. fig. 56. 
Achatinella nucleola Reeve, Conch. Icon. Achatinella, sp. 39 [zon Gould]. 
One young specimen I refer to this species. See a note under A. sudbrostrata 
Pie, 
Has. Oahu, Waianae Mts. (Newcomb, Perkins) ; Kapalama and Kalihi (Baldwin). 
(3) Amastra anucta Smith. 
Amastra amicta Smith, P. Zool. Soc. London, 1873, p. 86, pl. x. fig. 20. 
Dr Hartman notes that this species ‘“‘ may equal fefricola” ; it appears to me quite 
distinct. 
Has. Hawaiian Islands (Smith).
