FULGENS GROUP. 



45. Achatinella fulgens Newcomb. 



A.Julgens Newc. P. Zool. Soc. London, 1853, p. 131, pi. xxii, fig. 24, 24a. 



Shell elongately conic, polished, shining,; whorls 6, flatly con- 

 vex ; suture slightly impressed ; aperture ovate ; columella short, 

 tuberculated; lip simple, ribbed within; colour rich chestnut-brown, 

 with a broad white sutural fascia cutting the centre of the last 

 whorl ; apex and columella white. L,ong. 18/20, lat. 8/20 poll. 



Var. A. White, with broad chestnut bands. 



Var. B. Chestnut-coloured above, yellowish below, with two 

 black and one white band, the columella dark brown ; of large 

 size, measuring 22-20X 10-20 of an inch. 



This last variety may, upon further examination, prove to be 

 a distinct species. The locality of this last is Makiki Valley, 

 "Mauka roa," or far back in the mountain range. An examina- 

 tion of the respective animals will resolve the doubt. — Newc. 



Hab. Niu. — Newc. 



This and the following seven species are very nearly related, 

 and form a very interesting group. They are all found in the dis- 

 trict between Niu Valley and Makiki ; all are sinistral, and the 

 great number of color varieties run one into the other. Over one 

 thousand examples of this varied group are in the author's collection .

A. buddii Newc. P. Zool. Soc. London, 1853, p. 155 ; pi. xxiv, fig. 73.
