TORNATELLINID.E. 69 



the Hawaiian species are ovoviviparous. When cleaning the 

 shells nearly every adult animal contains from 2 to 4 embryos 

 in different stages of development. There is a great similarity 

 between the adult stage of Elasmias and very young stages 

 of Auriculella. 



The Hawaiian species of this genus are separated by the 

 presence or absence of palatal folds and the form and size of 

 the columellar callus. 



E. fusca has been found in Hawaii, East and West Maui, 

 Molokai, and Lanai ; E. luakahaensis on Oahu and Kauai ; 

 E. anceyana has so far only been collected only on West Maui. 



TORNATELLINA. Species of this genus have been taken 

 from about sea-level to nearly 5,000 ft. elevation. As far as 

 we know, T. baldwini is strictly arboreal, being found on the 

 leaves of shrubs and ferns. T. lanceolata is sometimes ar- 

 boreal, as a few of the specimens in the collection have been 

 taken in the leaf-axils of the ki, but most of the specimens 

 were found on the ground on the dead leaves of the ieie. T. 

 cylindrica is found only on the trunks of trees (especially the 

 lehua) under loose bark, moss or lichens. T. oblonga is usu- 

 ally terrestrial in its station. It is especially fond of dead 

 leaves, though occasionally taken on trunks of trees a foot or 

 two from the ground, and sometimes on old stone walls. T. 

 gracilis is strictly terrestrial in habit. All the specimens 

 which I have taken were under stones in very dry localities 

 and not far from the sea. 



Distribution. T. baldwini has been found on Kauai, Oahu, 

 E. Maui and Hawaii. It probably occurs on most of the other 

 islands. T. peponum and mcgregori are only found on Hawaii. 

 T. gayi is peculiar to Kauai. T. oblonga has been found on 

 all the islands except Kahoolawe and Niihau. T. cijlindrica 

 has been reported from Kauai, Oahu and Molokai. T. lanceo- 

 lata has been found only on Oahu. T. polygnampta occurs on 

 East Maui and Molokai. T. gracilis has been found alive on 

 Oahu and Kauai. Fossil specimens of this species have been 

 found on all the islands except Niihau and Lanai, which have 

 not been searched. 



Kauai has 4 species of Tornatcllina, of which one is peculiar
