This is a proposal to continue and extend work in progress on the systematics of salamanders from the western United States and from Middle America. The main emphasis of the study is the morphology and genetic variation of the species. The main morphological topic is the development and comparative structure of the brains of salamanders that use extreme fast and far- reaching tongues to capture prey. Comparative anatomical studies of other parts of the organism will also be conducted. Both protein and nucleic acid variation will be studied in a number of species. A long range goal of this study is to determine how many species of salamanders there are in these regions, and to determine the patterns of phylogenetic relationships among them, as they are important to our understanding of ecology and earth history.

这是一项提议，旨在继续对来自美国西部和中美洲的萨拉曼人的系统学的努力进行研究。 该研究的主要重点是该物种的形态和遗传变异。 主要的形态学主题是使用极端快速和遥远的舌头捕捉猎物的sal脑大脑的发展和比较结构。 还将对生物体其他部位进行比较解剖研究。 蛋白质和核酸的变化都将在许多物种中进行研究。 这项研究的一个远距离目标是确定在这些地区有多少种sal，并确定它们之间的系统发育关系模式，因为它们对我们对生态学和地球历史的理解很重要。
