380 FAUNA HAWAITENSIS 
TORNATELLINIDAE. 
TOoRNATELLINA Beck. 
Beck (Index Moll. 1837, p. 80) proposed this name as a subgenus of Achatina, and 
placed in it four species, all of them undiagnosed. Pfeiffer in 1841 (Symb. Hist. Helic. 
pt. 2, p. 5) diagnosed the genus and gave (p. 130) a list of species. Previously to this 
Anton had proposed (1839) S¢vodzZus, but in considering his claims it should be borne 
in mind that S¢oé2/a had twice previously been used in Zoology. 
The Hawatian species appear to be but little understood: the only attempt at 
figuring them was made by Gould, whose six figures, under one name, represent three 
different species. 
I have endeavoured to avoid the creation of synonyms by a careful study of the 
descriptions and measurements given by the various authors. The habitat in the case 
of these very small shells is not always reliable, as they are very liable to be transported 
with plants, &c.
