Toner Royal OntOA-io Museum of Zoology, Toronto As HAS BEEN MENTIONED before in this jour- nal, Logier and Toner, Can. Field-Nat., 56: 15, 1942; — Ibid., 56: 126, 1942; a check list of amphibians and reptiles of Canada, Alaska and Newfoundland is in preparation. The work is progressing but the need for more information and specimens is apparent. Data on many of our commonest species, away from centers of population, is lacking and it is only through the cooperation of other nat- uralists that such data can be secured. With this in mind, we present herewith in condens- ed form our locality records to date from all sources for the above named species. If any reader knowing of additional local- ity records not included in the following list would be kind enough to send such records, with as full data as possible, to the authors at the Royal Ontario Museum of Zoology at Toronto, the service would be greatly apprec- iated. In sending in a record, name the county, the township if known, and the town; or if taken at some distance from a town name the nearest town or post office and say how far from it, approximately, and in what direction. Give the name of the person who made the obsei-vation and state if the frogs (or frog) were seen or only heard, and the date of the observation if known. The list of localities follows, each of which is marked by a spot on the accompanying map of southern Ontario (we have no records from east of Ontario, or from north of a line drawn from Ottawa to Port Carling).
