46 Original Descriptions of Achatinella. 



Var. I). White at the base, and also above. 



Var. E. Covered with oblique reddish-brown streaks. 



Var. F. Apex tipped with black, passing into A. buddii Newc. 



Yar. G. Green or yellow, except the black bands, and a 

 narrow line of white. 



Var. H. White, with several fine spiral black lines accom- 

 panying the broader bands. 



Var. I. With black bands very broad, occupying half the 

 surface or more. 



Var. J. With two black bauds, one sutural, the other pass- 

 ing above the suture. 



Var. K. With two black bands, one sutural, the other enter- 

 ing the aperture ; rare. 



Var. L,. With several narrow bauds on the upper part of the 

 whorls. 



Remarks. Dextral specimens of this species are very rare ; 

 I have obtained but two. Varieties J and K have been found only 

 in Palolo. As in the preceding species, the specimens found in 

 Niu are of the lighter colored varieties, and more solid than those 

 of the other valleys. — Gk. 



Hab. Palolo, Waialae, Wailupe and Niu. — Gk. 



The characteristic feature of this species is its prominent black 

 bands. This and all the color varieties of A. divcrsa are very 

 closely related to the members of the fulgens group. The metrop- 

 olis of all these shells is the territory including the valleys of Niu, 

 Wailupe, Waialae and Palolo. Mr. Gulick, who has given such 

 full descriptions of the species of this and the fulgens group, adds 

 the following notes in regard to the species found in this section : 



"The variation of the species, both in form and color, and the 

 shading of the varieties of different species into one another, has in 

 many instances been noted ; but the affinities are more complicated 

 than would appear from the descriptions. From this cause, together 

 with the perplexity arising from dextral and sinistral varieties, from 

 lack of specimens representing many of the forms of the genus, and 

 from inability to ascertain the geographical relations of the species, 

 unavoidable errors found their way into Reeve's Monograph of the 

 genus, from which confusion has arisen in the nomenclature of the 

 species of this group especially. Additional error has since been 

 introduced, by the description, under new names, of certain speci- 

 mens of well known shells, which the demand for new and beauti- 

 ful species had subjected to artificial treatment. So successful was 

 the deception that some are still received as genuine, which I am 

 persuaded belong to this class.
