Scale bar mm. and chloride ions. The pH of bladder cell contents was determined to he Kmhryos develop within the atrial chamber of the adult zooids (Van Name, 1945). Because of their bright pink color they could be observed easily and were recorded in nearly all colonies collected between March 7 and August 18. Tadpoles were collected in the tadpole collector and settled on glass in order to observe the growth of zooids in the laboratory, the time course of spicule and bladder cell formation, and the method of budding. The time course of tadpole release (Fig. 5) reveals that more tadpoles were released after 3 to 4 hr in the light following overnight dark adaption under black plastic than at any other time, and tadpoles were released more or less continuously all day. Colonies left in an uncovered aquarium overnight in order to observe their reaction to natural dawn also released larvae sporadically throughout the day. Cystodytes tadpoles are large, with a mean body length of mm (n = 25, "), tail length of mm (n == 25, == ), and tail width of 80- 70 • 60 SO 40 30 20 10- 3456 Hours in light FIGURE 5.
