(Dec. 1856). 
Newcomb regarded this as a variety of A. perdix Reeve; not having seen speci- 
mens which unite them I have left it as a species. Clessin (Nom. Helic. Viv. p. 
306) placed it—erroneously—under A. marmorata Gould. 
Has. Maui, Lahaina (Gulick) ; Huelo (Baldwin); Waihee (Perkins).

Partula densilineata Reeve, Conch. Icon. Partula, sp. 9. 
Has. ? Maui (Baldwin). 
The specimens in the British Museum are labelled “Oahu”, but probably this is 
erroneous and Maui is the correct habitat. 
(64) <Achatinella (Partulina) redfieldi Newcomb. 
Achatinella redfieldi Newcomb, Ann. Lyc. New York, vi. (May 1853), p. 22; t. c 
p. 325 [animal]; P. Zool. Soc. London, 1853 [1854], p. 131, pl. xx. fig. 5; 
Gwatkin, P. Ac. Philad. 1895, p. 238 [radula]. 
The long series collected by Mr Perkins has given me considerable difficulty. 
Newcomb originally gave both Maui and Molokai, Clessin (Nom. Helic. Viv. p. 306) 
gave Molokai and Kauai (the latter being obviously wrong), and Mr Baldwin gives 
Mapulehu, Molokai. I think Maui was a slip, due to confusion with the very closely 
allied A. splendida, and that A. redfeldi is really a Molokai shell. Next arises the 
question of what the typical form may be ; Newcomb states that the shell is either plain 
or banded on the third whorl oxzZy, while he gives six as the number of whorls, the shell 
figured being banded (as A. sp/endzda) on all the whorls. The forms I refer to this 
species are: 
a. Typical (Plate XI. fig. 15). Varies from nearly white to chestnut, sometimes 
being particoloured. 
Has. Makakupaia, Molokai (Perkins).
