Show 260 MR. E. A. SMITH ON THE MOLLUSCA [May 6, whitish zone at the periphery and a very narrow one a little above; also a broad band beneath the suture, and the linear one, above referred to, immediately above. The remaining specimens differ in having, above the peripheral white band, a rich brown one, which is continuous up the spire just above the sutural line. 2. HELIX (PHILINA) BIGONIA, Ferussac. Hab. Melanipa, Basilan Straits, Philippines. The single dead shell at hand is of a rather depressed form, the body-whorl in consequence being more acute or subcarinate around the middle. The species has been recorded from Samar, another island of the Philippine group. 3. HELIX (PLANISPIRA) ZONARIA, Linn. Hab. Amboyna. 4. HELIX (PLANISPIRA) TORTILABIA, Lesson. Hab. Amboyna, Moluccas, and Aru Islands. The specimens from both these localities belong to the variety D in Martens's account of the land-shells of the ' Preussische Expedition nach Ost-Asien,' being wax-yellow, unhanded, and having a white peristome. On p. 392 of this work he questions the correctness of Amboyna as the home of this species ; but in this instance the Cumingian collection is not at fault, as so frequently is the case. 5. HELIX (ALBERSIA) ZONULATA, Fe'russac. Hab. Aru Islands, and Amboyna, Moluccas. 6. HELIX (CAM<ENA) SANZIANA, Hombron and Jacquinot. Hab. Mehnipa Island, Philippines. This species was collected by Mr. Cuming at Samboanga, south of the island of Mindanao. This place is not far from Malanipa, a very small island in the strait between the former, Mindanao, and Basilan to the south. 7. HELIX (GEOTROCHUS) PILEUS, Miiller. Hab. Aru Islands. 8. HELIX (GEOTROCHUS) CERTNERIANA, Pfeiffer. Hab. Aru Islands. 9. HELIX (HELICOBULIMUS) SARCINOSA, Ferussac. Hab. Hoilo, Philippines. 10. BULIMUS (ORTHOSTYLUS) FAUNUS, Broderip. Hab. Cebu, Philippines. 11. BULIMUS (CANISTRUM) FULGETRUM, Broderip. Hab. Hoilo, Philippines. |
