NEMATODE PARASITES OF BIRDS 241 



DISPHARYNX LAPLANTEI Seurat, 1919a 



Synonym. — Acuaria {Dispharynx) laplantei Seurat, 1919. 



Hosts. — Primary : Garrulus glandarius cervicalis; secondary : Un- 

 known. 



Location. — Proventriculus. 



Morphology. — Dispharynx (p. 237) : Body large, attenuated at ex- 

 tremities. Cordons similar to those of D. noctuae and D. spiralis. 

 Postcervical papillae tricuspid, subsymmetrical ; Seurat says they are 

 situated as in D. spiralis, directly in front of the level of the excre- 

 tory pore, but according to his figures the excretory pore is 590/* and 

 390/x from the head end in the female and male respectively, whereas 

 the cervical papillae are 612/* and 672/* from the head end in the 2 

 cases. Mouth with 2 large triangular lips. 



Male 7.7 to 8.4 mm. long, with a maximum width of 300/*; much 

 slenderer than female. Cordons 455/* long. Caudal extremity 

 coiled in spiral. Cloacal aperture 370/* from tail end. Four pairs 

 of preanal and 5 pairs of postanal papillae, arranged as in D. noctuae 

 and D. spiralis. Right spicule 240/*. long, thick and falciform; left 

 spicule 865/* long, slender, pointed at tip, and not alate. 



Female 9.9 mm. long by 565/* wide. Cordons 805/* long. The 

 massive body narrows suddenly posterior to the vulva, which is in 

 the posterior third of the body, 2.87 mm. from the tail end; vulva 

 not salient. Vestibule (fig. 304) extends 150/* anteriorly, then sud- 

 denly turns posteriorly, a large unicellular gland being situated at 

 this point; the descending branch is 320/* long and joins the branches 

 of the varnish gland (trompe), there being no unpaired varnish 

 gland. Anus 170/* from tip of tail. Eggs 37/* by 25/*, thick-shelled, 

 embryonated when oviposited. 



Life history. — Unknown ; probably involves intermediate stages in 

 other hosts. 



Distribution. — Africa (Medea and Ain Ograb).
