P repre- sents pouch; open arrows, jelly; solid arrows, gill. The bar in Figure 14 represents 100 /j.; bar, Figure 15, represents 50 yellowish-white color. The first cleavage divisions appear to divide the egg into four large blastomeres, but it is not known whether the cleavage furrows in the ital area are more than superficial. Development occurs at the animal end of the egg in a manner, described by Spannhof and Spannhof (1972), as similar to that.
