Preferred Abstract (Original): 

Two new forms of cercariae are described from the fresh water snail Melanopsis tuberculata collected from Azraq Oasis and East Ghor Canal, Jordan during 1983 and 1985, respectively. Cercaria sp. I is a xiphidiocercaria belonging to the "Pusilla" sub-type. It has 3 pairs of penetration glands and a flame cell formula 2[(2+3+1+2)+(2)]= 20.Cercaria sp. II is an ocellate, apharyngeal brevifurcate cercaria. It has 5 pairs of penetration glands and a flame cell formula 2[(1+1+1)+(1+1)+(1)]= 12. Both cercariae develop in sporocysts

Preferred Abstract (Original): 

Two new forms of furcocercariae are described from the fresh water snail Melanopsis praemorsa collected from Menshiya Station at Jordan River and Jarash Falls, Jordan during 1984 and 1985. One is pharyngeate longifurcate monostome cercaria and the second is pharyngeate longifurcate distome cercaria. These cercariae are named Cercaria melanopsis XIV and XV. Both forms of cercariae develop within long thread-like sporocysts. Details are presented on the morphology and behaviour of these cercariae
