160 STRONGYLOIDEA 



accessory branches originate together from each branch. An 

 accessory j)iece present. Vulva in posterior third of body. 

 Uterine branches opposed, but the posterior branch turns and 

 runs anteriorly. 



Hab. Intestine of Elephants and Rhinoceroses. 

 Genotype : Q. [Evansia] renniei (Railliet & Henry, 1913).

8. Bourgelatia Railliet, Henry & Bauche, 1919. 



External leaf-crown composed of about twenty large, 

 pointed elements. Internal leaf-crown with about forty 

 elements. Buccal capsule shallow, cylindrical, its wall in two 

 thick portions, of which the posterior is more or less continuous 

 with the cuticular lining of the wide, shallow oesophageal 

 funnel. Ventral rays of bursa parallel and closely applied to 

 each other. Bursa incised near the tips of the ventral rays, 

 giving the appearance of a pair of additional lobes. Antero- 

 lateral ray somewhat shorter than, but not divergent from, 

 the remaining lateral rays. Externo-dorsal ray originates 

 high up on the main dorsal stem. Dorsal ray cleft for almost 

 half its length. A single accessory branch springs from each 

 main branch. An indistinct accessory piece present. Vulva 

 close to anus. Uterine branches parallel. 



Hab. Intestine of Pigs (one species known). 

 GenotjqDC : B. diduda Railliet, Henry & Bauche, 1919.

Raillet, Henry & Bauche suggest that this form belongs to 

 the Oesophagostominae, in spite of the absence of a ventral 

 cervical groove. Certainly the single pair of accessory 

 branches of the dorsal ray suggests relationship with the 

 Oesophagostomes, in which the second pair of accessory 

 branches is much reduced or absent, but since the grouping of 

 that subfamily has been based almost entirely on the presence 

 of a ventral groove, we have no alternative but to include the 

 genus under discussion in the Trichoneminae, at the same 

 time remarking that it is perhaps the nearest relative of the 

 Oesophagostominae . 



9. Kiluluma Skrjabin, 1916. 



Mouth-collar divided by grooves into six sections, each 

 bearing one of the cephalic papillae. An external leaf-crown 

 of six elements present, these arising from the base of the 

 buccal capsule and projecting from the mouth-opening.
