New Information and Reappraisals Concerning Some Alien and Indigenous Snake Records from the Federated States of Micronesia and the Mariana Islands

New information is presented on old records of four species of snakes from four different islands in Micronesia. A record of Dendrelaphis caudolineatus from Saipan is reexamined and the specimen reidentified as D. philippinensis, and a snake from Pohnpei previously recorded only as an unidentified species of Dendrelaphis is identified as D. punctulatus striolatus. We also provide supplementary data on circumstances surrounding records of a brown tree snake, Boiga irregularis, from Chuuk, and a yellow-bellied sea snake, Hydrophis platurus (Pelamis platura), from Kosrae.
