A Study of Some Cercariae obtained from Molluscs in the Sudan

Abstract

In a previous paper1 we gave an account of three non-furcocercous cercariae found in Bulinus contortus in the Sudan. During further investigations on the intermediate hosts of Bilharzia, other cercariae have been found in molluscs collected in different districts of the Sudan. As their post-larval development has not been studied, the classification of these cercariae has not been attempted; the procedure of giving them numbers rather than names, indicating specific peculiarities, has been continued.
