FULGENS GROUP. 

 45. Achatinella fulgens -Newcomb. 



A.fulgena Xewc. P. Zool. Soc. London, 1S53, p. 131, pi. xxii, fig. 24, 24a. 



Shell elougately 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. Long. 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 colledlion .
