Howell, T.R. 1948 Clubhouse, Tilden Park, Contra Costa Co., Calif. March 22 - Two Hyla were marked thusly: Along a small rocky stream nearby Aneides lugubris (small one) and an Ensatina e. xanthoptica were found, both under rocks. Batrachocaps were very abundant Several Triturus were present in the stream, and under a rock another Ensatina, which rose up, and the whole tail oozed a thick milky secretion. It stood on its toes (see sketch), Under another rock I found a centipede clutching a pale yellow egg mass, which she (presumably) was reluctant to leave but did. 2 ♂♀ Triturus f. loaded with eggs were found in a relatively dry spot under a rock. An adult A. lugubris was located under bark, and a small Ensatina + minute (about ½") Batrach. under a small log.
