37350	Eaton, Theodore H. (Theodore Hildreth)	The Ancestry of Modern Amphibia: A Review of the Evidence			.txt	text/plain	7793	475	58	A recent paper by Hecht (1957) discusses many features of _Necturus_ and _Proteus_, and shows that they are remote from each other; his evidence does not seem to prove, however, that they were of independent origin or that they need be placed in separate families. VERTEBRAE AND RIBS Development of the vertebrae and ribs of Recent Amphibia has been studied by Gamble (1922), Naef (1929), Mookerjee (1930 a, b), Gray (1930) and Emelianov (1936), among others.
