362 PARTULINA. 



ment was found on the southern rim of the bowl near the 

 summit of Mauna Loa, where no doubt forests survived long 

 after it had disappeared in the neighborhood of Moomomi, 

 where the shell occurs much less than a hundred feet above 

 sea level.

 original lot. His type figure is copied photographically on 

 pi. 29. 



Var. kamaloensis P. & C., n. v. PL 26, figs. 4, 4a. 



Between the branch ravines above the Kamalo amphitheatre 

 and below the old irrigation ditch we collected in three simi- 

 lar colonies of redfieldii. The shells were very abundant on 

 leafless and often dead lantana. They are mostly large, 

 capacious, and cinnamon brown to chestnut brown or burnt 

 umber in color, most old ones lighter by weathering and loss 

 of cuticle, sometimes to a dull, pale ochraceous buff tint. 

 Rarely the fresh shells are ochraceous buff, with or without a 

 dark band. Very few shells have numerous dark bands on a 

 pale ground. As the colonies are of considerable extent, and 

 nearly homogeneous in character, it may be well to have a 

 name for this particular race.

PARTULINA CRASSA (Newc.). Page 40. 



The dull form of P. crassa described by Newcomb and in all 

 the older collections was probably found near the western end 

 of Lanai, now a deforested region where they still occur as 

 fossils. In the Koela region the shells are of a fine dark brown 

 color. 



P. KAAEANA Baldwin. Page 41. Mr. Thaanum thinks that 

 this may be identical with or a variety of P. ustulata Gul. (p. 

 47). Unfortunately a careful search failed to locate the type 

 of ustulata in the Boston Society collection. It seems to be 

 lost. No topotypes are extant, and the ustulata from other
