ACHATINELLA DECIPIENS. 145 



Oahu: Ahonui, Kalaikoa, Wahiaiwa, Helemano, Opaeula, 

 Kawailoa and Waimea (Gulick). 



Achatinella nympha GUL., Ann. Lye. Nat. Hist, of N. Y., 

 vi, 251, pi. 8, f. 69, 1858. 



Merely a variety of pulcherrima, from which it differs by 

 the ivhite lip, -which however is dark-edged in some examples 

 of Gulick 's lots. It differs from recta, by the 'conspicuous 

 thickening of the lip. Some of the large lot in the Gulick col- 

 lection have a narrow dark sutural band, but most of them 

 have none, and in some the suture has a white border. In a 

 lot from Wahiawa the patterns are in these numbers : yellow 

 ground bandless 6, with bands or lines 25 ; chestnut ground, 

 bandless 20, banded 9 shells. 



According to Gulick, Helemano is the metropolis of 

 nympha. The specimens figured are from Helemano (pi. 32, 

 fig. 14) and Wahiawa (pi. 27, figs, 7, la, 11 ; pi. 32, fig. 13). 

 Fig. 13 is too deep in odor. The shell is much lighter, -what 

 Ridgway calls barium yellow. PI. 27, fig. 5g, might be re- 

 ferred to nympha as well as to pulcherrima. 



Dr. Cooke, who examined the type of A. aptycha Pfr. (see 

 p. 54) , considers it a form of nympha. The figure is repro- 

 duced in my pi. 30, fig. 1.
