340 LAMINELLA, MAUI. 



Baldwin, do not seem specifically separable from Lahaina 

 picta, though their markings are heavier, and the shape more 

 oblong. The mouth is pink (pi. 53, figs. 7, 8). Possibly they 

 represent a variety or subspecies. 



Dr. Newcomb describes the animal as " densely black, sur- 

 face checkered by fine lines of a light color; tentacles slate, 

 much produced; mantle and bottom of foot brownish-black; 

 when extended same length as the shell. ' ' 



Other shells (four in a lot of 38 from Lahaina, Gulick coll.) 

 have the spire somewhat more concave, and opaque white, 

 but showing a few small dark dots; the last whorl is suban- 

 gular in front, and becomes more or less streaked and 

 speckled with blackish or dark green on the last half. The 

 aperture is flesh-colored within the base. Length 17.8, diam. 

 10 mm. ; whorls 6%. These white-spired shells are entirely 

 like some of the young of Kula bulbosa received from Gulick. 

 The possibility of accidental mixture must be considered. 



8. L. BULBOSA (Gulick). PI. 53, figs. 13, 14, 15. 



" Shell sinistral, imperforate or sometimes slightly per- 

 forate, subpyriform, rather solid, unpolished, striate, yellow-
