ANCEY : LAND SHELLS FOUND IN HAMAKUA DISTRICT, HAWAII. 69 



ribs on the last whorl ; its palatal folds are very close to each other, the most 

 deeply seated (the inferior) beginning near the end of the superior. Besides, 

 there is a very slight point-like denticle far within the base. 



15.— Aehatinella physa, Newc. var. proeera, Anc. 



I have not seen good full-grown examples, but refer, with some doubt, 

 a very young shell to this. 



Mr. Sykes has changed the well-known name A. pliysa, Newc, to 

 confusa, Sykes, because he supposed A. hawaiiensis, Bald., to equal the true 

 ■plnjsa. Mr. Baldwin writes that his liwi-aiiensis, was discovered in a spot

 tains and the Hamakua slope of Mauna-kea. 



16.— Amastpa senilis, Baidw. 



17— Amastpa fossilis, Baidw. 



18.— Amastra, sp. 



A juvenile specimen, with conic spire and keeled body-whorl, probably 

 distinct from the former species. 



19.— Leptaehatina henshawi, Sykes. 

 Probably referable to this species, although not so strongly sculptured. 



20.— Leptaehatina konaensis, Sykes. 



21.— Leptaehatina arborea, Baidw. 



22.— Leptaehatina simplex, Pease. 



23.— Leptaehatina. sp. 



A puzzling form, somewhat like the Maui L. (jrana, Newc.

25.- -Leptaehatina, sp. 



Like the latter, but larger and with a more produced spire. 



26.— Tornatellina neweombi, Ffr. (?) 



27.— Topnatellina eineta, Anc. 

 Quite identical with typical specimens found in a living state on Maui, 

 Oahu, and Hawaii. 



28.— Tornatellina proeerula, Anc. 

 Large examples. Also from Maui,
