34 LEPTACHATINA, GROUP F. 



West Maui: Maunahoomaha (Thaanum, Cooke), Hono- 

 kahau Gulch, Honokowai Gulch, lao Valley (Thaanum), 

 Kauaula, Honolua (Baldwin). 



, A rather abundant species on West Maui. Two lots of 

 shells in Mr. Baldwin's collection from Makawao and Ula- 

 palakua, East Maui, are provisionally located in this species. 



L. ovata is most closely related to L. vitreola Gul. It dif- 

 fers in its smaller size, shorter and more ovate spire, larger 

 aperture, and being proportionally broader. In some speci- 

 mens the sutural band is lacking.

Newcomb 's description in the P. Z. S. differs slightly from 

 the original one given above. He gives the form as " elon- 

 gately conic " and the length as 0.25 inch (6.2 mm.). The 

 figure accompanying the description does not agree with the 

 measurements given in either of his two descriptions. In the 

 figure the breadth is a little more than one-half of the length, 

 while in the original description it is just one- third. 



In the collection of the Academy of Natural Sciences of 

 Phila. (no. 57810) is a tray of shells labeled grana,, presented 

 by the author. This tray contained two distinct species. 

 Some of the specimens (pi. 2, figs. 26, 27) agree closely with 

 Newcomb 's original description, having the following meas- 

 urements: length 6.1, diam. 2.7, length of ap. 2.7 mm.; the
