350 LAMINELLA, MOLOKAI. 



Length 14.2, diam. 7, aperture 6 mm. ; 614 whorls. 



Molokai : Cotypes no. 104716, A. N. S. P., and 1818 Univ. 

 of "Wisconsin. 



Eight specimens of this race were in a collection presented 

 by Mr. Jos. Button to the University of Wisconsin. By its 

 size and the sunken streaks of the most fully marked shells 

 it evidently belongs to venusta, but the pattern is practically 

 identical with semivenulata, which so far as seen is invariably 

 larger and yellow. 



13c. Yar. orientalis n. v. PL 51, fig. 11. 



This name is proposed for the dextral form from Puukaeha 

 (on the -central ridge near the east end of Molokai) , figured 

 by Borcherding as Laminella luteola Fer. (Zoologica, p. 86, 

 pi. 8, fig. 19). The figure indicates a rather deep yellow shell 

 of the size of A. venusta. Whether the race at that place is 

 dextral, or only the specimen figured, is not stated. Bor- 

 cherding 's figure is copied. The real luteola Fer. is probably 

 a Hawaiian Amastra. See p. 321.
