Show 1880.] OF FERUSSACIA AND ITS ALLIES. 665 =Lovea [emend. Loweai], Watson, P.Z. S. 1875, p. 677 : type Ferussacia tornatellina, Lowe. The animal of this group is well described and figured by the Rev. R. Boog Watson, I. c. (?) Subgenus CYLICHNIDIA, Lowe (Ann. & Mag. Nat. Hist. 1852: types Ferussacia leacockiana and F. cylichna, Lowe, sine descr.). The animal of these two species not being known, correct classification is necessarily rather doubtful; I have little doubt, however, that the subgenus is correctly placed here. Subgenus HYPNOPHILA, Bourg. (Rev. et Mag. Zool. 1858 : type Ferussacia pupeeformis, Cantraine). = Cryptazeca, Folin, Bull. Soc. Borda, Dax, 1877: type Ferussacia monodonta, Folin. Animal admirably described (I. ci) by the Marquis de Folin. (?) Subgenus HOHENWARTIANA, Bourg. (Rev. et Mag. Zool. 1858 : type Ferussacia hohenwarti, Rsm.). Another section of which the correct classification still seems very doubtful; I am inclined to think it will prove more nearly allied to Ccecilianella than to Ferussacia! (?) Subgenus PSEUDOSTREPTOSTYLA, Nevilh A new subgenus, which I propose for the remarkable form described in m y paper on the Land-Shells of Mentone (P. Z. S. 1880, p. 134) as Ferussacia (?) abnormis. Its classification is also still very doubtful. B. Without mucous pore. Genus Z U A , Leach (Syn. Brit. Moll. 1820 : type Helix lubrica, Miiller, publication disputed ; also of Gray's Manual, 1840). = Cionella, Jeffr. Linn. Soc. Trans. 1830 : types Helix lubrica, Miill., and Turbo tridens, Pult., =Azeca tridens, fide Jeffr. 1864, Brit. Conch., should be Cochlicopa, Fer. Prod. 1821, & c , as restricted by Risso, 1826. = Cochlicopa, section Styloides, Ferussac, Prod. &c, 1821, part., which cannot, however, be retained as Cochlicopa ; if maintained at all, must be applied to the marine form Halia priamus. If Zua be not accepted, Cionella must be used ; undoubtedly Zua and Azeca are very closely allied. Genus AZECA, Leach (Leach, Syn. Moll. Brit. 1820 : type Turbo tridens, Pulteney, publication disputed ; also of Turton's Manual, 1831. = Cionella part.), Jeffr. /. c. PROC. ZOOL. Soc-1880, No. XLIV. 44 |
