PARTULINA, MAUI. 49 



92712 A. N. S. P. Another lot from Waihee is similar, but 

 contains some individuals marked somewhat like marmorata. 



1 ' Var. 6. Ash-brown with whitish streaks and spots. This 

 variety passes into A. undosa. 



"Var. c. With a white band on the periphery of the last 

 whorl; very rare. 



"Var. d. Small, ovate-conic. The dimensions of one of the 

 smallest specimens are as follows: length 18, breadth 10, length 

 of aperture 8f mm. Weight 4 grains. 



"Var. e. Lip considerably expanded and reflected, slightly 

 thickened within; columella broadly reflected. This variety 

 presents a remarkable feature; appearing as if the body-whorl 

 had been enlarged and the lip expanded by a second growth 

 after the shell has been perfected and the lip thickened. The 

 second growth forms a broad lip sometimes an eighth of an inch 

 or more in width from the interior callous ridge to the edge. 

 This lip seem to be of the same material as the thickening 

 within, the exterior being of an unpolished ivory color, not 

 covered with the brown coat which clothes the rest of the shell. 

 The interior of both the lip and columella is of polished ivory 

 white; aperture within the lip bluish white. Specimens pre- 

 senting more or less of the features of this variety are not rare '
