Family, Spikueid®. Genus, Spiroptera 
Spiroj)tera megastoma 
Mule. Attached to stomach mucous membrane. Wau, Bahr-El-Ghazal. 
Spiroptera megastoma is a stomach parasite of eqnines that is too well known, both in 
Egypt and Europe, to require more than a note of its occurrence in the Sudan. 
Family, Filabid.®. Genus, ? Filaria 
Filaria, sp. ? 
Bat— Megaderma frons. Body cavity. Bor, Jebel Eiver. 
A single specimen was found in the body cavity of a Megaderma frons. It measures Filaria 
20 mm. in length, is immature and a female. Accordingly it does not provide sufficient data 
for determination as any one definite species. The absence of a male is very regrettable, as 
Filarice appear to be very rare in the Vespertilionid®. Rudolphi records Filaria vcspertilionis 
from Vespertilio discolor, V. hechsteinii, and v. Linstow Filaria vesperuginis from Vesjierugo 
serotinus, to neither of which our specimen is likely to belong. 
Filaria agamce. Eodhain, 1900 
Lizard— Agama colonorum. Embryos in blood. Wau, Bahr-El-Ghazal. 
This is a short, stout and sheathed embryo measuring about 66p, the sheath being about Filaria agamtr 
a third longer. Eodhain has described and figured it in “ Centralbl. f. Bakt. u. Par.,” XLI., Abt. 1, 
Grig. 1906, p. 545. The adults wei’e found by him in the cellular tissue beneath the skin, but 
were lost in transit and have consequently not been described. Dr. Wenyon came across the 
embryos only. The name F. agamce was used only incidentally liy Eodhain in an explanatory 
note that accompanied the figure, and does not appear in the text. There seems no objection 
to its adoption, though its use was probably intended for descriptive rather than systematic 
purposes. 
Genus, Filaria 
Filaria hufonis, sp. nov. 
Toad— Bufo regularis. Connective tissues. Nasser, River Sobat. 
Relatively few filaria have been noted in the Amphibia. Stossich was able to collect only Filariabufmis 
seven known forms for his monograph in 1897. I have found no records of further finds since 
that time. 
Dr. Wenyon mentions in his notes that the embryos of this filai'ia are exceedingly 
common in the blood of toads at Nasser. Of the five adult specimens collected, four were
