Species of Molokai. 



The data on distribution of Molokaian species is fragmen- 

 tary, and little profitable systematic work can be done 

 until the field is well explored. Borcherding has done val- 

 uable work by recording definite localities and giving good 

 figures; but by dragging in the species luteola and remyi, 

 surely not Molokaian, and by identifying depicta as venusta, 

 he gives an impression of scrambled Laminellas. We heartily 

 join in his belief that the species are excessively variable and 

 rich in transition-forms.

The shell is sinistral, narrowly perforate or closed, narrowly 

 pyramidal with obtuse summit and straight lateral outlines; 

 thin but strong. The glossy surface is marked with very fine 

 growth-lines and near the summit there are usually some shal- 

 low pits or cicatrices below the suture. Embryonic whorls 

 nearly smooth, dark purple or pale; subsequent whorls but 

 slightly convex, yellow or pale brownish-yellow or dull orange, 

 typically marked with black or blackish-brown veins which
