While working at Rovigno during April and May, 1909, 
I examined a few of the common wall-lizards (Laccrta 
mural is), which occurred abundantly on the neighbouring 
islet of Figarola, as in the time when Prowazek studied the 
intestinal flagellates of this reptile (26). My object was really 
to see if a Trypanosome also occurred in it, Prowazek not 
having stated whether he examined the blood for that purpose 
or not; but 1 did not succeed in finding any Trypanosomes.

and again later by Labbe (13), who placed it in a distinct 
genus, Karyolysus. I was too much occupied with othei-
