reached England in too damaged a condition for identification. Donlitlesfi they were 
hrought in on boats or hy lierds of cattle. 
During the summer of 1!)07 I s])ent eight weeks on the Upper White Nile and the 
Sobat, and near Taufikia obtained eggs of the lihick seroot, T. h/'ijiittd.his, Wied. The 
larval from these were brought to Khartoum and reared in the laboratory. 
Among the seroots noticed in the vicinity of Nasser, on the Sobat, were T. sociiis, 
T. hii/iittntiif!, T. nfricanuis, Gray, T. fiisciatiis, Fab. v'ar. ?iilof.iciis, Aus., and T. pnr., Walk. 
In some localities on the White Nile, T. dfricaiius — and probably other sjiecies of 
similar appearance — is known to the natives as 'Ver-el-ijufur (“ bird ” or “ Hying thing of 
camel sickness ”), owing to the belief that exists among tliem that it is the cause of the 
common camel disease. For this note T am indebted to Mr. C. E. Lyall.
