The variation is, as usual in the group, very great. A long series collected by 

 Mr Hutchison, added to those of Mr Perkins, has led me to be unable to form any 

 definite break between the various described species which are here placed as varieties. 

 A. pulcherriina appears to be a large race in which the colouring has been broken into 

 bands. A. imdticolor and A. recta are, I think, only dwarf varieties. The sinistral 

 shell figured by Pfeiffer {loc. cit. pi. xxx. fig. 1 1 a) as a variety of A. multicolor 

 belongs really to A. ovifonnis. A. nympha seems a small, elongate, almost colourless 

 variety, with a white lip. 



(22) Achatinella [Bulimella) decipiens Newcomb. 



Achatinella decipiens Newcomb, P. Zool. Soc. London, 1853 [1854], p. 153, 

 pi. XXIV. fig. 68 ; Ann. Lye. New York, vi. p. 332 [animal]. 



Achatinella viridans Pfeiffer, Mai. Blatt. 1854, p. 121 [nee Mighels, fide New 

 comb]. 



Achatinella planospira Pfeiffer, P. Zool. Soc. London, 1855, p. 3, pi. xxx. fig. 8. 



Achatinella herbacea Gulick, Ann. Lye. New York, vi. p. 233, pi. viii. fig. 52. 



Achatinella scitula Gulick, /. c. p. 241, pi. viii. fig. 61. 



Hab. Oahu, Kahana (Newcomb, Baldwin); Koolauloa (Hartman); Waimea, 

 Kawailoa, Hakipu (Gulick). 



(23) Achatinella {Btiliviella) /aba Pfeiffer. 



Achatinella {Btdiinella) faba Pfeiffer, P. Zool. Soc. London, 1859, p. 30. 

 Hab. Hawaiian Islands. 



I cannot trace this species in the Brit. Mus. ; it seems not to have been recognized 

 by any recent author. 



(24) Achatinella [Buliniella) glabra Newcomb. 



Achatinella glabra Newcomb, P. Zool. Soc. London, 1853 [1854], p. 139, pi. xxii.

Achatinella fricki Pfeiffer, op. cit. 1855, p. 3, pi. xxx. fig. 7. 



Achatinella platystyla Gulick, Ann. Lye. New York, vi. p. 196, pi. vr. fig. 25. 



Achatinella wheat leyi Newcomb, MS. 



Hab. Oahu, Kawailoa to Hauula (Baldwin); Koolau poko (Newcomb); Ka- 

 waiawa (Hartman) ; Kawailoa (Guhck and Perkins). 



Only two dead specimens. I think A. fricki, which Newcomb placed with 

 A. ovata, really belongs here ; fig. 7 a, however, belongs to A. ovata. The determina- 

 tion of ^. wheatleyi is from specimens so named in the Brit. Mus.
