(also Polillo), lignaria, Pfr., rufogaster, Less., macrostoma, Pfr., vidali, Hid., bicolorata, Lea (also Alabat), polillensis, Pfr.

(also Alabat). Catanduanes, 3 : imperator, Pfr., codonensis, Hid., turbinoides, Brod. Marinduque, 4 : marinduquensis, Hid., bicolorata, Lea, philip-pinensis, Rve., villari, Hid. Samar, 2 : philippinensis, Rve., pithogaster, Fer. Leyte, 1 : turbinoides, Brod. Panay, 3 : turgens, Desh., bicolorata, Lea, sarcinosa, Fer. Cebu, 4 : pithogaster, Fer., faunus, Brod., sarcinosa, Fer., daphnis, Brod. Bohol, 2 : gilva, Sby., daphnis, Brod. Masbate, 3: pithogaster, Fer., faunus, Brod., ticaonica, Brod. Siquijor, 1 : daphnis, Brod. This subgenus is largely developed in Luzon and the central islands, but entirely absent from Mindoro and Mindanao. Several species are of wide distribution, e. g., pithogaster (Luzon, Samar, Cebu, Masbate), daphnis (Cebu, Bohol, Siquijor), turbinoides (Luzon, Catanduanes, Leyte). Cochl. rustica, Mouss., from Java, must be an Amphidromus: C. viridis, Desh., from Madagascar, is a Helix. 9. PHENGUS. Luzon, 2: romblonensis, Pfr. (Calaguas only), opalina, Sby. Marinduque, 7 : romblonensis, Pfr., quadrasi, Hid., cossman-niana, Cr., simplex, Jon.,eburnea, Rve., mbllendorffi, Hid., subcarinata, Pfr. Romblon, 1 : simplex, Jon. 1 Burias, 1 : concinna, Sby. This subgenus has its headquarters in Marinduque, and appears to have spread only to the islands in the immediate vicinity. 10. CANISTRUM. Burias, 2: ovoidea, Lam., stabilis, Sby. 2 Masbate, 1 : ovoidea, Lam. A small but well-marked subgenus of correspondingly well-marked distribution. Its true limitations have been indicated above. 1 To these should perhaps be added cincinniformis, Sby., Luban, on the authority of a private collector, but I do not feel justified in placing it in the text. Pfeiffer strangely classifies the species in Cochlodryas. 2 Ilocos Sur (N. Luzon) is given as a habitat for balanoid.es, Sby., by a private collector, but the authority is hardly sufficient. |
