(62) Achatviella {Pariulvia) pyramidalis Gulick. 



Achatinella pyramidalis Gulick, Ann. Lye. New York, vi. p. 204, pi. vii. fig. 32 

 (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 (Norn. Helic. Viv. p. 

 306) placed it — erroneously — under A. mannorata Gould. 



Hab. Maui, Lahaina (Gulick) ; Huelo (Baldwin); Waihee (Perkins). 



(63) Achatinella {Partulina) radiata Gould. 



Achatinella radiata Gould, P. Boston Soc. 11. 1845, P- -7- 

 Btdinms gouldiV{€\^(tr, Zeitsch. fiir Malak. 1846, p. 116. 

 Partula deiisilineata Reeve, Conch. Icon. Partttla, sp. 9. 



Hab. ? Maui (Baldwin). 



The specimens in the British Museum are labelled "Oahu", but probably this is 

 erroneous and Maui is the correct habitat. 



(64) Achatinella [Parttilina) redfieldi Newcomb. 



Achatinella redfieldi Newcomb, Ann. Lye. New York, vi. (May 1853), p. 22 ; t. c. 

 p. 325 [animal]; P. Zool. Soc. London, 1853 [1854], p. 131, pi. xxii. 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 arid 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. redfieldi 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 only, while he gives six as the number of whorls, the shell 

 figured being banded (as A. splendida) on all the whorls. The forms I refer to this 

 species are : 



a. Typical (Plate XL fig. 15). Varies from nearly white to chestnut, sometimes 

 being particoloured. 



Hab. Makakupaia, Molokai (Perkins).
