(Plate XX., figs. 1-8.) 



Dr. T. L. Bancroft recentl}' forwarded from Queensland to us 

 some blood-films labelled " Drepanidia from the green tree-snake, 

 Dendrophis punctulatus Gray, 10/12/07." The erythrocytes were 

 lieavily parasitised by a lia^mogiegarine belonging to the subgenus 

 Kari/olysus, which varied in size from 0-009 by 0-0015 mm. to 

 0-018 by 0-002 mm. The youngest forms were delicate thin 

 cre.scents with rather pointed ends, and a well defined nucleus 

 situated centrally. Somewhat older forms (about 0013 mm. long 

 by 0002 mm. broad) were broader, their ends being blunt and 

 rounded. The nucleus was usually placed nearer one end (the 

 posterior) and varied in size and shape. Sometimes it was narrow 

 and band-like, at others an elongate and more or less rounded
