TORNATELLINA. 187 



Species of Juan Fernandez and Masafuera. 



None of these forms are known to us by specimens, and 

 we are ignorant of their relationships to Polynesian species, 

 in view of the remoteness of these Chilian Islands from the 

 Pacific archipelagoes, a new investigation of their land faunas, 

 which are at least partially of Pacific type, is highly desirable. 

 It should be noted that there are related shrubby Com- 

 positse and other plants in Hawaii, Tahiti and Juan Fernan- 

 dez, and that the genus Fcrnandczia stands very close, in con- 

 chological characters, to the Hawaiian Leptachatina. 



T. bilamellata, 110. 1, 1ms been reported from both Juan 

 Fernandez and Oipara. T. trochlearis, no. 35, from Opara 

 and Masafuera. There seems to have been an early mixture 

 of shells from these distant localities. 



Leptinaria lacryma and L. succinealis Beck, Index Mollus- 

 corum, 1837, p. 79, from Juan Fernandez, are probably Tor- 

 natellinas. Neither has been defined in any way. 



47. T. MINUTA (Anton). PI. 40, fig. 7. 



Long-oval, spire lengthened, not veiitricose, last whorl as 

 large as the others together; somewhat glossy, finely striate, 

 light brown; aperture long-oval. Breadth l /z, height l 1 /^ 

 lines (Anton).

Achatina minuta ANTON, Verzeichniss, etc., 1839, p. 44, no. 

 1592. Tornatellina minuta Anton, PFEIFPER, Symbol ad 

 Hist. Hel., ii, 1842, p. 130; Monographia, ii, p. 392. KUES- 

 TER, Couchyl. Cabinet, Pupa, p. 150, pi. 18, figs. 14, 15. 



The figure is copied from Kuester. Pfeiffer described a spe- 

 cimen received from Anton as follows: Shell ovate-oblong, 

 very finely striatulate, pellucid, corneous, glossy; spire tur- 

 rite-conic, apex a little obtuse ; whorls S 1 /^, a little convex, the 

 last about two-fifths the total length. Aperture oblong, sub- 

 auriform, contracted by a strong white lamella on the parietal 

 wa.ll and a callously twisted columella. ; peristome acute. 

 Length 3, diam. l 1 /^ mm., aperture \ l /s mm. long.
