R ECORDS of reptiles and amphibians new to the Oregon list and additional records of rare forms have come to light in the course of our collecting during the past 7 years. Many of our records extend the ranges of old and well known species, and occasionally show them to be present in entirely new and unexpected places. Our collecting has been confined to a large extent to the region west of the summit of the Cascade Mts., though one of us (Jewett) has collected east of the Cascades as well as in, the western region. The Cascade region is one of the most promising fields for collecting. This is borne out by the fact that within the time covered by our work a new species and one new genus have been found in this region. A systematic and thorough account of ranges and habits of our amphibians and reptiles is much to be desired. The nomenclature of the Check List of North American Amphibians and Reptiles (3rd ed.) is followed throughout, except for forms described since its appearance. |
