Perdicella fulgurans Sykes. Fauna Haw., 1S90, vol. ii, p. 329, pi. xi, fig. 5. 



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

 bus confertim sculpta, albida, strigis fulgurantibus castaneis elegantissime 

 picta, svitura modice impressa, apice obtusvilo; anfr. 5 1-2, plano-convexi, 

 ultitnus 2-3 longitudinis testa sequans ; apertura ovato pyriforinis, intus 

 lilacina; peristoma margine dextro simplici, columellari subrcflexo; plica 

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

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

 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 prett}' shell is akin to P. zcbriiia Pfr., but ma}- be readily 

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

 proportion to the length, and b}^ the color-pattern being finer in 

 design and more zigzag. — Sj'kes.

 this part of Maui.
