aperture and posterior to the posterior testis. Despite the fact that 

 Poirier's (1886) description of G. delphini is so somewhat incomplete, 

 the writer feels that a restudy of specimens of this species will show 

 it to be specifically distinct from C. falliata and perhaps to belong 

 to a different genus. Aside from the shape of the ovary and testes, 

 it appears to be more closely related to the genus Lecithodesmus than 

 to the genus Campula, but the writer prefers to leave it in the latter 

 genus until an examination of specimens of these forms is possible. 



CAMPULA ROCHEBRUNI (Poirier, 1886) Bittner and Sprehn, 1928 



Plate 3, Figures 11-12 



Synonyms. — Bistomuin rodiebruni Poirier, 1886, pp. 36-37; 

 Cladocoelium rochehruni (Poirier, 1886) Stossich, 1892, p. 11; 

 Brachycladium roche'bruni (Poirier, 1886) Looss, 1899, p. 558. 



Description. — Camfula: Body narrow, 10 mm long by 1 mm wide; 

 ventral surface flat, dorsal surface slightly convex. Cuticle beset 

 with very slender spines, which are especially abundant and close 

 together on the anterior part of body. Suckers equal in size, 380/x 

 in diameter (Poirier gives the diameter as 0.038 mm, but this un- 

 doubtedly is an error for 0.38 mm) and 700/x. apart. Pharynx 490)n 

 long by 180/i wide ; esophagus very short ; intestine as in C. delphini. 

 Genital aperture immediately cephalad of acetabulum; cirrus pouch 

 short and wide, preacetabular. Testes large, ovoid, tandem in posi- 

 tion, and situated near equator of body. Ovary small, spherical, 

 situated cephalad of anterior testis and to right of median line; 

 Mehlis's gland more elongated and situated to left of ovary. Vitel- 

 laria composed of anastomosing tubular glands and extending over 

 the greater part of body ; the vitelline ducts do not anastomose in the 

 anterior and posterior parts of body as in C. delphini. Uterus with 

 few loops, situated between Mehlis's gland and genital sinus. Eggs 

 oval, 82/x long by 45/x wide, strongly pointed posteriorly. 



Host. — Delphinus delpJiis. 



Location. — Liver. 



Distribution . — Europe. 



Genus LECITHODESMUS Braun, 1902 



Generic diagnosis. — Campulinae: Body long, slender, and flat- 

 tened dorsoventrally. Suckers widely separated. Intestinal ceca 

 provided with median and lateral dendritic diverticula. Cirrus 

 pouch extending slightly beyond posterior margin of acetabulum; 

 cirrus unarmed; testes branched. Ovary deeply lobed; vitellaria in 

 quadrangular groups of follicles extending from region of pharynx 

 to posterior end of body. Parasites of cetaceans. 



Type species. — Lecithodesmus golinth (van Beneden, 1858) 

 Odhner, 1905.
