l895- ^O '^^ SOUTH-AFRICAN EXTOMOSTRACA. 45 



more or less distinct orange hue, caused by the translucent ovarial ova 

 contained \vitliin the boily. 



Observations. This form tleveloped in immense quantities in some 

 of my aquaria, and in one of them has been domesticated until the present 

 time. Among the numereous specimens examined, not even a single male 

 could ever be detected, and I am therefore much inclined to believe, that 

 this form is exclusively partenogenetical. In habits it agrees with the 

 other species of the genus, being a rather active swimmer.
