26 THE NAUTILUS. 



Near Dove, Marion Co., Term., on "East slope of Battle 

 Creek valley among rocks." Collected by H. H. Smith in 

 1906. Types No. 7100 of my collection, paratypes in collec- 

 tions of the Academy of Natural Sciences, Philadelphia, and 

 Dr. Bryant Walker, Detroit, Mich. 



Had this form been found in any other region it might 

 equally well have been considered a variety of alternata, but 

 being found in the region of cumber landiana I think it best to 

 make it a variety of that species. 



ACHATINELLA HUNTING IN NORTHWESTERN OAHU. 



We take the liberty of printing extracts from a letter received 

 some time ago from Mr. Irwin Spalding of Honolulu, in expla- 

 nation of the interesting photograph of living Achatinellas re- 

 produced on plate II. As a general rule, these snails are found 

 "sleeping" by day, on the under side of a leaf as in the pic- 

 ture, under loose bark, or in a knot hole. They are doubtless 

 active chiefly by night. 



Those who have used the monograph in the Manual of Con- 

 chology know that many species and color-races once abundant 

 are now rare, some doubtless extinct. Dr. Newcomb and Mr. 

 Gulick collected fine tree-shells in quantity where forests are 

 now but a tradition, and their shells are often of color-patterns 

 strange to the modern collector. It is most gratifying to learn 

 that some of these long-lost species are being turned up at 

 higher levels. Mr. Spalding writes as follows: 



"So many good things have come my way along the land- 

 shell line these last two months that I really don't know how 

 to begin and tell you all about them. To start in with, I spent 

 my three weeks vacation this year collecting on Oahu, started 

 in at Opaeula and worked around through Waimea, Pupukea, 

 Waialee, Kahuku, Leie, finally landing up at Hauula. Only 

 2367 Achatinella and Amastra for the trip, but here is the best 

 of it all, found four of the supposed extinct species, A. buli- 

 moides ; A. emersoni ; typical old-time, banded mottled A. curta, 

 and last but not least, A. ? ; the latter to be seen in the ac-
