EIMEKIA. 181 



zoites takes place while the oocysts and sporocysts are floating 

 in the fluid in the gall-bladder. Oocysts pass into the alimentary 

 canal and are expelled with the faeces, fresh infection taking place 

 by these being ingested. 



Dimensions — Schizonts 12-21 //,; merozoites 8-10 )(a by 

 1-3-1-5/i ; microgametocytes 16-17 /x ; oocyst 17-34 /x in length 

 by 11-15/x in width ; sporocysts 7-9 /u, by 5-7^ ; sporozoites 

 9-13/x by l-04;Li 



RemarTcs. — Setna and Bana (1935 h) described this parasite 

 as a new species under the name of E.flaviviridis,3ind observed 

 both schizogony and sporogony taking place within the gaU- 

 bladder. Development of the oocyst is completed in 62 hours 

 within the gall-bladder, or within 54 to 61 hours outside the 

 body of the host under experimental conditions. 



Rarely oocysts containing three sporoblasts and three sporo- 

 cysts were encountered, but one of these was double the size 

 of the others and developed four sporozoites, the total number 

 of sporozoites being thus the normal mmaber eight. 



Knowles and Das- Gupta (1935) have recorded three species 

 from the same host. In their " species B " the oocysts range 

 in size from 17-22^ in length by 12-15 /x in breadth. They 

 also met with occasional giant forms measuring over 30 ju, 

 in length, and remarked that they possibly corresponded 

 with the species observed by Bana and reported by Setna 

 (1933). The oocysts reported by Setna and Bana measured 

 25-34 /x in length and 11-14^ in breadth. It is thus highly 

 probable that E. flaviviridis described by Setna and Bana 

 from Bombay and " species B " described by Knowles and 

 Das-Gupta from Calcutta are identical. 



The species shows a very close resemblance to E. agamse 

 Laveran & Pettit, 1910, as regards the occurrence of both 

 schizogony and sporogony in the gall-bladder and bile-ducts 

 and in the form and dimensions of the oocysts, but differs as 

 regards the form of the sporocysts. In E. agamse the oocysts 

 are more or less elongated oval, measuring 20-25 /x by 11-14)li, 

 and the sporocysts fusiform, measuring 8/x by 4ju,. In 

 E. flaviviridis the sporocysts are ovoid, and measure 7-9 /x 

 by 5-7^. 



Habitat. — Gall-bladder and intestine of the Hzard, Hemi- 

 dactylus flaviviridis (Riippell) : Bengal, Calcutta ; Bombay, 

 Bombay.
