body by a series of wavy loops on side of body opposite ovary, 

 ascending through a similar course on opposite side of body to region 

 of testes, here making complete transverse loops both posterior and 

 anterior to testes before passing to genital pore, Metraterm weakly 

 developed. Ova thick-shelled, operculated, containing fully developed 

 embryos when oviposited, 27^1 to 30/i by 39/x to 45^. Vitellaria fol- 

 licular, placed in superficial mesenchyme of lateral and dorsal regions 

 of body, extending from level of anterior margin of ovary to anterior 

 margin of oral sucker, not overlapping caeca. A single yolk duct 

 from each side fusing with its neighbor in region just posterior to 

 acetabulum to form yolk reservoir. Genital pore ventral, in mid- 

 line just in front of acetabulum. Testes large, equal, 0.145 mm in 

 diameter, at about level of equatorial plane of body, slightly behind 

 level of acetabulum, one slightly in advance of other (when ovary 

 is right, right testis is more posterior), or directly opposite. Vasa 

 e£Ferentia uniting on entering cirrus sac. Cirrus sac club-shaped, 

 reaching to caudal margin of acetabulum, containing vesicula semi- 

 nalis, pars prostatica with its gland cells, ductus ejaculatorius, and 

 weakly developed cirrus. Excretory system typically that of the^ 

 genus as described for B. viesorchium. 



Host. — Leiolojnsma later ale (Say). 



Habitat. — Small intestine. 



Localities. — New Orleans and Pearl River, La., and Calhoun 

 Falls, S. C. 



Type specimen.— v. S.'^.M. Helm. Coll. no. 9028. 



Remarks. — Brachycoelium ovale perhaps shows a closer relation- 

 ship to B. ohesum and B. lynchi than to any of the other members of 

 the genus. The smaller size of the suckers, the general size and 

 shape of the body, the smaller ova, the extent and distribution of the 

 vitellaria, and the position and size of the reproductive glands are 

 sufficient to separate it from its nearest relatives. 



BRACHYCOELIUM TEITURI Holl, 1928 



Plate 8, Figukes 5-7 



Brachycoelium trituri was described by Holl (1928) from the intes- 

 tine of the spotted newt {Tritums viridescens) collected at Durham, 

 N. C. The form appears to be a valid species, although HoU's 

 description was too brief to include morphological details, only 

 measurements being given for the various organs. I am able, how- 

 ever, to assign to this species five specimens from the small intestine 

 of the grass frog {Rana sphenocephala) collected at Harvey, La., two 

 specimens from the small intestine of Pseudacris occidentalis col- 

 lected at Kenner, La., and five specimens from the small intestine of 

 Desmognathus fuscus fuscus collected at Athens, Ga. Certain varia-
