Of the sixteen species of shells obtained at Christmas Island, belong to well-known forms, but two, a. Succinea and a. Littorina, appear to be new. No locality has been previously assigned to Nerita maxima, and Littorina picta has hitherto been known from the Sandwich Islands only. All or most of the marine forms occur both in the Malay Archipelago and Polynesia. The Melampi have an equally wide distribution ; and the species of Succinea, although considered distinct, like most others of the genus, bears a great resemblance to those from other parts of the world. The following is a list of the species :- *1. Terebra crenulata, Linn. 2. Columbella (Pusiostoma) mendicaria, Lamarck. 3. Sistrum ricinus, Linn. (var. albolabris). 4. Mitra virgata, Reeve. 5. Ranella cruentata, Sowerby. *6. Triton chlorostorna, Lamarck. * These species are all inbahited by Paguri. |
