Cell inclusions in the oogenesis of scorpions

Abstract

Although the very remarkable mitochondria of the male germ cells of scorpions have attracted in the past a number of workers (12 and 13), no work had so far been undertaken on the female germ cells. In the present work two different groups of scorpions, with and without ordinary yolk in their oocytes, were selected for study in the hope that some light might be thrown on the relationship between the nucleus and yolk formation. Euscorpius napoli and Buthus judaicus were selected as the representatives of those forms whose oocytes contain ordinary yolk, and Palamnœus fulvipes madraspatensis and Palamnœus swammerdami as the representatives of forms without any such yolk.
