222. Achatinella fulgurans Sykes. 



Perdicella fulguram Sykes. Fauna Haw., 1890, vol. ii, p. 329. pi- *i. Ar. 5. 



T. subperforata, dextrorsa, ovato-turrita, nitida, sublente lineis spirali- 

 bus confertim sculpta, albida, strigis fulgurantibus castaneis elegantissime 

 picta, sutura modice impressa, apice obtusulo; anfr. 5 1-2, plano-convexi, 

 ultimus 2-3 longitudinis testa ajquans ; apertura ovato pyriformis, intus 

 lilacina; peristoma margine dextro simplici, colurnellari subreflexo; plica 

 columellaris torta, subprominens, mediocris, rapide ascendens. Long. 16, 

 lat. 8; long, apert. 8.1, lat apert. 4.9 mill. 



Shell subperforate, dextral, ovate-turreted, shining, under a 

 lens densely marked with spiral lines, whitish, most beautifully 

 colored with shining chestnut stripes, suture moderately impressed, 

 apex somewhat obtuse; whorls 5 1-2, plano-convex, the last equal 

 to 2-3 of the length of the shell; aperture ovate-pyriform, lilac 

 within; lip simple at right margin, columellar margin subreflexed; 

 columellar fold twisted, quite prominent, moderate, ascending 

 rapidly. 



This pretty shell is akin to P. zebrina Pfr., but may be readily 

 separated from it by its greater size, by being much broader in 

 proportion to the length, and by the color-pattern being finer in 

 design and more zigzag. — S} r kes. 



Hab. Makawao to Huelo. — Bald.

223. Achatinella ornata Newcomb. 



A. ornata Nevvc. P. Zool. Soc. London, 1853, p. 149, pi. xxiv, fig. 55. 



Shell sinistral, acutely pyramidal, shining; whorls 6, plano- 

 convex, margined above; suture well impressed; aperture subquad- 

 rate in adult, subovate in immature shells; lip slightly thickened 

 at the edge; columella broad and flattened; surface of shell covered 

 with alternating undulations or zigzag markings of white and 

 black arranged longitudinally, with the subcentral transverse black 

 band, sometimes margined with a white one below on the last 

 whorl. L/Otig. 10/20, lat. 4/20 poll. 



This is an extremely rare species, found in a limited locality 

 in a deep ravine at the back of Lahaina. — Newc. 



Hab. Iyahaina. — Newc. 



This does not seem related to any of the other shells found in 

 this part of Maui.
