Red Salamander Spelerpes ruber The red salamander, Spelerpes ruber (Daudin), ranges throughout the eastern half of the United States. It is, however, local in its distribution, being very common in certain places, and decidedly rare in others seemingly as suitable in a single neighborhood. It is more ac^uatic than others of our eastern salamanders, preferring cold springs to any other habitat. Here they may sometimes be found in great nvmibers. I have taken at least 68 from a single swamp spring near Haverford College, Pennsylvania. In the natural state its food is small earthworms and sowbugs. In one speci- men I found a caterpillar of the army worm. In captivity it will eat finely chopped beef. Large larvae will eat very small ones. The identification of the adult is an easy matter. It cannot be mistaken for any of the salamanders of the Northeast, except Gyrinophihis porphyritiens, which is larger, more uniform in color, and re- stricted to the AUeghenies. The adult ruber reaches 5>< inches. The ground color is a clear red. The upper surface is crowded with black spots which are sharply defined in the small specimens, but in old and large animals are out- lined with dusky, which mav obscure the ground color on the back. In the voung the belly is unspotted, but very fine black spots appear with age. The tail is about two-fifths the total length. The larvae are more difficult to iden- tify. The ground color is white, and the pigment is uniformly distributed over the dorsal surface, except for a few small spots called )Mgmentless areas, which arc
