49] STUDIES ON GREGARINES—KAMM 49 



Sporonts associated in pairs. Length 60^1. Ratio LP : TL :: 1 :3 to 

 4; WP:WD::1:L Protomerite dome-shaped, deutomerite tapering 

 to a blunt point. No constriction at septum. Nucleus large, spherical, 

 15/i in diameter. 



Cyst and spores unknown. 



Intestine of Hyale pontica Rathke (Nicaea Nilsonii). 



Taken at Naples. 



There is an equal possibility of this species belonging with the Cephaloi- 

 dophoridae and with the Aggregatidae from the characters recorded. 

 The exact position can only be determined after cyst and spores (or their 

 absence) are demonstrated.
