70 TORNATELLINID/E. 



to that island. Oahu has 5 species, one of which is peculiar. 

 Molokai has 4 species, of which none is peculiar. Lanai has 

 only the widely-spread species, T. oblonga. Maui has 4 

 species, only one of which, T. polygnampta, extends to the 

 neighboring Island of Molokai. Kahoolawe has only the 

 widely-spread T. gracilis; and Hawaii has 5 species, two of 

 which are peculiar. 



TORNATELLIDES. The species of this genus are found from 

 about sea-level to nearly 8,000 ft. elevation, or as far up as 

 there is any vegetation. Some of the species are arboreal in 

 habit, especially those belonging to the group of T. compacta, 

 of which all the species, though sometimes found on dead 

 leaves, are usually taken on the leaves of ferns, grass and 

 shrubs. The species belonging to the group of T. perkinsi are 

 usually found on dead leaves and twigs, and specimens are 

 occasionally taken on low plants. Practically all of the 

 species belonging to the group of T. tcrclra are terrestrial in 

 habit. The only two living species of the group of T. cypho- 

 styla were taken on the trunks and branches of trees and 

 shrubs. The species belonging to the groups of T. euryom- 

 phala and T. thaanumi are not only terrestrial but also live 

 on the stems and leaves of ferns, grasses and shrubs. 



TORNATELLARIA. All the species of this genus are strictly 

 terrestrial in habit, being found on dead leaves and twigs, 

 fallen logs and mossy stones. Occasionally a specimen is 

 taken on a damp, mossy tree-trunk a foot or two from the 

 ground. The living species seem to prefer rather damp locali- 

 ties. Fossil specimens are found in localities which are ex- 

 tremely dry at the present time.
