302 FAUNA HAWAIIENSIS 



var. kitcorraphe Gulick. 



Apex leucorraphe Gulick, P. Zool. Soc. London, 1873, p. 79, pi. x. fig. 2. 

 Hab. Oahu, Kalaikoa. 



var. cinei'osa Pfeiffer. 



Achatinella {Bulimella) cinerosa Pfeiffer, P. Zool. Soc. London, 1855, P- 2, 

 pi. XXX. fig. 5. 



Hab. Oahu. 



It is with much dififidence that the above 'lumping' has been attempted. While 

 not very difficult as a general rule to identify single specimens, I have been unable to 

 divide the long series of specimens which, partly collected by Mr Perkins and partly by 

 Mr Hutchison, have passed through my hands. Shape, colour, and form, seem to be 

 as nothing, and one passes by infinitesimal graduations from one so-called species to 

 another. True it is that the animals are said to differ in colour, but this alone is not, in 

 my opinion, sufficient for a specific character ; even if it be so, it can, in general, only 

 avail the field naturalist, and not the Museum student. 



The variety neglecta Smith is not really so greenish as represented in the original 

 figure ; fig. 23 on the same plate gives a better idea of the real colour. 



Ferussac appears to have confounded more than one distinct form under his decora ; 

 the name has therefore been here used for the species he first referred to. 



(8) Achatinella doliuni Pfeiffer. 



Achatinella {Bulimella) doliuin Pfeiffer, P. Zool. Soc. London, 1855, p. 5, pi. xxx. 



fig- 15- 

 Hab. Molokai (Baldwin). 



I fancy this habitat must be wrong and that the species really belongs to Oahu ; 

 the shell is very close to A. hanleyana Pf., and may prove to be only a colour variety. 



(9) Achatinella hanleyana Pfeiffer. 



Achatinella {Bulimella) hanleyana Pfeiffer, P. Zool. Soc. London, 1855, p. 202. 



Related to the form of A. lorata described as A. nobilis, and may prove to be an 

 extreme variety. 



Hab. Oahu.
