Lateriporus gen. nov. sp. nova is characterized by an ext- 

 remely elongated Laurer's canal which opens to the exterior 

 not on the dorsal side, as usually, but on the right edge of 

 the body. 



II. Genus Laureriella gen. nov. 



Diagnosis: Parasites of average size with a smooth cuticle. 

 Oesophagus elongated, the intestinal trunks reach to the end 

 of the body. The genital aperture is situated anteriorly to the 

 ventral sucker, medially. The bursa cirri is small, not reaching 

 the level of the middle of the ventral sucker. Pars prostatica is 

 developed. The round testes are arranged medially one after 

 another. The spherical ovary lies in the space between the 

 anterior testis and the ventral sucker, medially. The vitelline 

 glands are situated on both sides of the intestinal trunks. 

 In the posterior part of the body the vitelline glands of the 

 right side join those of the left side. Laurer's canal fs 

 extremely long and opens to the exterior on the right side 

 of the body, not on the dorsal. The few convolutions of the 

 uterus are arranged in the space between the anterior testis 

 and genital aperture, the loops of the uterus passing a little 

 beyond the lateral margin of the intestinal coeca. Parasitic 

 in the intestine of reptiles. Type and meanwhile the only 

 species: Laureriella lateriporus Skrjabin 1915. 



2. Laureriella lateriporus nova sp. 

 (Tab. 1. Fig. 1.) 



Host: Lizard N2 18 (from fam. Chamaeleontidae). 



Occurence: Intestine. 



Description of the species. 



Body flat, equally rounded at both extremities. Length of 

 the body reaches 6,12 mm. at a maximum width — 1,275 mm. 

 in the middle. A round-oval oral sucker the aperture of which 

 is directed ventrally attains 0,476 mm. in length, with a width 

 of 0,51 mm. The pharynx adjoining it has 0,30 mm. in dia- 

 meter. A rather long oesophagus, attaining 0,37 — 0,4 mm., 

 is continued into the intestinal trunks reaching the posterior 

 end of the body. 



Tw^o spherical testes, having 0,.';1 — 0,54 mm. in diameter, 

 are situated medially one after another in the posterior part
