J.D. Anderson 1959 Journal Feb. 14 Valonia Lagoon, Rio del Mar vicinity, Santa Cruz Co., Calif. Left MV2 about 8:10 am. Drove via Bayside Freeway, Hwy Rte 9/17 to Santa Cruz, then south on Rt 1 to Rio del Mar. Worked Valonia Lagoon with dip net until 1 pm. Hoped to find small horse but got only 1 nearly hatched larvae + many eggs which are close to hatching. Eggs are in shallower parts of pond near living dead Eleotharus stalks, as is usual. Very few tadpoles seen. Only Hyla regilla + these all tiny, newly hatched larvae. Fresh Hyla eggs seen, though most were in late stages - hatching. Ostracods fantastically abundant. Did not see any fairy shrimp. Drove to New Tiger Pond next (1 mi. N W Ellicott Rd Sta, 4mi. W Watsonville, Santa Cruz Co., Calif.). This pond had filled prematurely in early Jan. + had ad. tigrinum in it on Jan. It was completely dry on Jan 21 + Jan 24. But is now full to max capacity - result of recent rains. Worked this pond from 1:30 - 2:30 pm. Got fresh A. tigrinum eggs along margins of pond. Many H. regilla eggs mature - all fresh - only cleavage to telotula. As usual no adult tigrinum were taken during day despite turning all banks etc in the cup + dragging bottom of pond with net. Drove to Ellicott Pond - 1/2 mi. N W Ellicott Rd Sta, 4mi. W. Watsonville, Santa Cruz Co., Calif. Water was muddy here. Worked all along edges for larvae of A. m. croceum + A. tigrinum. Got only 4 very small tigrinum larvae. Did not see
