species. Barreto says the ovejector of Si diff evens is 677/* long, the 

 vestibule being very long (338/*), and united to the trompe by a small 

 sphincter. The figures of various species of Subulura show inter- 

 esting variation in this general type of structure: S. seurati (p. 126) 

 and S. leprinei (p. 118) show the side entrance into a slightly devel- 

 oped bulbous cavity, while S. allodapa (p. 108) shows it even more 

 highly developed, as does also S. forcipata (p. 115). Eggs almost 

 spherical, 59/* by 50/i, thin-shelled, containing an embryo when 

 oviposited (fig. liQd). 



Life history. — Unknown; probably similar to that of Ascaridia 

 galli (p. 82). 



Distribution. — Europe (Italy), Africa (Dahomey, Guinea, Belgian 

 Congo, Union of South Africa and Algeria) and South America 

 (Brazil). 



SUBULURA BRUMPTI (Lopez Neyra, 1922) Cram, 1926 



Synonyms. — Allodapa suctoria of Seurat, 1914, Heterakis suctoria 

 of Gendre, 1909; Subulura suctoria of Gedoelst, 1916; Allodapa 

 brumpti Lopez Neyra, 1922. 



Hosts. — Gallus gallus and Meleagris gallopavo. 



Location. — Ceca. 



Morphology. — Subulura (p. 104). Yellowish worms with curved 

 cephalic extremity, the concavity of the curve dorsal. Cephalic alae 

 (fig. 159a) finely striated transversely and extending the anterior 

 sixth of the body length. Buccal cavity divided into well-differen- 

 tiated zones, with 3 small teeth situated at the origin of the esoph- 

 agus. The length of the esophagus and its bulb is 1/7.25 of body 

 length in male and 1/9.5 of body length in female. Nerve ring about 

 *4 of length of esophagus proper, without bulb, from anterior end. 

 Intestine enlarged at union with esophageal bulb. 



Male 6.9 to 10 mm. long by 340 to 420/* wide. Tail ends in a pro- 

 longation about y 3 of length from cloacal aperture to end of tail. 

 Caudal sucker 170 to 220/t long, 340 to 500/* anterior to cloacal aper- 

 ture and 590 to 815/* anterior to end of tail. Five pairs of preanal 

 (according to Lopez-Neyra (fig. 159&), Seurat, and the present 

 writer; according to Gendre (fig. 161) and Gedoelst (fig. 160) 6 

 pairs) and 5 pairs of postanal papillae; of the postanal, 2 pairs of 

 small papillae are near the median line toward the end of the tail, 

 anterior to this a third and larger pair, more lateral, and then 2 

 pairs of larger papillae nearer the median line; the caudal glands 

 open between the second and third pairs, the pore apertures resem- 

 bling minute papillae; of the preanal papillae, the first 2 pairs 

 posteriorly may be regarded as adanal, a third pair is just preanal, 

 a fourth pair is about V3 of the distance from the posterior border 

 of the sucker to the cloacal aperture, and a fifth pair is at the side
