Page 468 - ... ie towards their free edges — which are of course terminated by the mesenterial filaments. Each gonad now consists on its outer side of a series of closely set irregular sperm acini with definite open spaces in their centres, hence, more or less ripe. On the inner side the acini are more rounded and less crowded, but some trace at least of the central space is visible. The ova, generally 2 to 4, appear on the inner edge near the upper end of the mass, and are at first quite minute. No further...
