mon elsewhere. The most numerous variety of the cognata 

 form is straw-yellow with the sutural line tinted with rose or 

 purple rose. A rose or purple-brown variety with a central 

 yellow band is found in no other part of the island."

Besides the common typical rose-colored form (figs. 1, 2), 

 the following color-patterns occur. From Garrett's remarks

2, form purpurascens Pfr. Dull purple, the aperture and 

 lip violet, common (fig. 3). 



3, form bipartita. Upper surface rose (fig. 4) or purple 

 (fig. 5) base pale yellow, the lip white. "Frequent in the 

 metropolis of the species but very rare elsewhere " (Garrett) . 



4, form bicolorata. Spire rose or purple, fading at the 

 end of penultimate whorl to straw yellow or corneous on the 

 last whorl; apex whitish; mouth and lip white (figs. 6, 7). 

 Common. 



5, form straminea. Straw-yellow or yellowish-corneous, 

 the apex or whole spire corneous- white ; aperture and lip
