﻿COPEPOD GENUS PUPULINA (CALIGOIDA) — WILSON 263 



ured) ; slightly shorter than the caudal rami; as long as the caudal 

 rami. These must represent different growth stages of the mature 

 copepod; they differ from the adult only in their lesser lengtli, in hav- 

 ing the anterior and posterior parts of the body approximately equal 

 in length, the carapace not so wide, and in very slight differeiicos in the 

 dorsal pattern of the genital segment. 



Color. — MacGinitie (1947) has recorded this species as being trans- 

 parent and W'ithout colored markings; eyespot black. 



Remarks. — MacGinitie has further noted that this species was para- 

 sitized by a trematode, the egg cases being attached mainly to the ab- 

 dominal area. It may or may not be of significance that the right 

 caudal ramus of the holotype female, which is a little shorter than the 

 left, and the left genital process of the paratype female, which is a 

 little shorter than the right, are each much more heavily infested by 

 the trematode &gg cases than any other area. 



The name hrevicauda refers to the very shortened caudal rami, 

 particularly conspicuous in the female, though it is to be noted that 

 those of the male are comparatively much shorter than those of other 

 species.
