400 ALDO CASTELLANI AND ARTHUR WILLEY. 
examination of the blood of an Ophiocephalus striatus 
from the Colombo Lake in May, 1905, gave negative results. 
We have also found Trypanosoma in the blood of 
Macrones cavasius (Siluride) and in Gobius giuris. 
Asa mere matter of fact we may mention that we have never 
observed Trypanosoma associated with endoglobular para- 
sites in the same host, nor have we found Trypanosoma in 
any species of animals in which we have found endoglobular 
forms. 
Dr. Hanna has described a Trypanosoma in the blood of 
the Indian Crow (Corvus splendens), and we have seen 
Halteridium in this species as well as in the Black Crow 
(Corvus macrorhynchus), both examined in the month of 
August, also, as mentioned above, in the common babbler, 
Crateropus striatus, examined in July, and in the 
common Scops owl, Scops bakkamcena, var. mala- 
baricus in July. All these hosts are more or less open to 
the charge of foul-feeding, and all frequent the neighbour- 
hood, sometimes even the precincts, of human habitations. 
MM. Laveran and Mesnil have described Trypanosoma 
solex, from Solea vulgaris, in association with Hemo- 
gregarina simondi.!} 
VI. Finarta. 
Besides Filaria immitis in the dog and Filaria vivi- 
para, v. Linstow, in the Indian crow, we found a Filaria in 
the blood of the Brahminy lizard, Mabuia carinata, and 
described it in our preliminary note under the name of 
Filaria mansoni.” Dr. von Linstow has since pointed out, 
in a paper which will shortly be published in ‘ Spolia Zey- 
lanica,’ that this name had already been applied by Cobbold 
in 1880 to a species of Filaria from the orbit of Gallus 
gallinaceus, and he accordingly proposes the new name 
Filaria tuberosa, so that the species now reads F. man-
