transparent, shining, moderately smooth, with very faint ob- 

 lique stria? (as seen under the lens), bright yellowish horii-

 5, convex, impressed at the suture, the last equaling about half 

 of the length ; aperture ovate, with a thin central vertical 

 tooth ; columella twisted and entering spirally ; peristome 

 simple ; acute. Length 1 line, diam. y 2 ; length of aperture 

 1^ line" (Brazier).

Tornatcllina inconspicua BRAZIER, P. Z. 8., 1872, p. 619 ; 

 Memoirs of the Australian Mus., no. 2, p. 27. PFR., Mouogr., 

 viii, p. 319. HEDLEY, Kecords of the Australian Mus., i, p. 

 142. 



We learn from Mr. Hedley's publication that the " type 

 was deposited in the Australian Museum, but has been acci- 

 dentally destroyed. Habitat, a gully on the North Eidge 

 among dead leaves, rare." It has not been figured. The 

 columella, "twisted and entering spirally", raises a suspicion 

 that this species is a Tornatellinops, and not really "some- 

 what perforate ' ' ; yet the one observation is as likely to be 

 wrong as the other. 



3. Galapagos species. 



The occurrence of Tornatellides in the Galapagos is unex- 

 pected, though it is not the only Pacific element in the fauna 

 of American islands. Juan Fernandez and Cocos Island (see 

 Manual, Vol. XVIII, p. 325, XXI, p. 93, and this volume, p. 

 187) also have some Polynesian or Micronesian genera.
