86 CH. WARDRLL STILES AND ALBERT HASSALL 



DiAGNOSis. — Fasciolinae with génital pore situateci anterior to 

 antero-lateral of oral sucker ; teslicles and ovary in about the 

 midcUe of the body, between tlie intestinal caeca and distal of 

 acetabulum. Testicles round or elongate ; on same transverse 

 plane oroneposteriorto theother ; cirrus-pouch very long, extending 

 nearly or quite to the acetabulum. Ovary anterior of testicles ; 

 vitellogene glands moderately developed, latéral of intestinal caeca ; 

 utérine coils irregular, situated for the greater part in posterior 

 portion of body distal of testicles. Oral sucker subterminal ; 

 oesophagus well developed, extending about half way to acetabu- 

 lum ; pharyngeal bulb présent ; intestinal caeca simple, long, 

 extending beyond testicles to posterior portion of body. Hosts : 

 Reptiles and Birds.

 gracile Leidy, 1856 = Distoma heterostomum Y{udol])h\, 1809. 



Leidy originally proposed Clinostomum with the two new species 

 C. gracile and C. dubium, but did not designate any type. We hâve 

 re-examined the originals of C. gracile but are unable to fmd the 

 originals of C. dubium. Looss descv\bed as Distomum reticulatum a 

 form which is evidently identical with Leidy's C. gracile, as 

 Leuckart bas already surmised, and Monticelli (1888) took Looss's 

 species as basis for bis genus Mesogonimus. As nothing dehnite is 

 known of C. dubium, and as Leidy himself evidently based bis 

 genus on C. gracile, we must accept this species as type, and 

 suppress Mesogonimus as a synonym. While inclining to the belief 

 that this genus is valid, it seems to us contain an assemblage of 

 species which must be furtber divided,
