Morphology. — Ascaridia (p. 77): Cuticle cross-striated with pe- 

 culiar markings (the figure which Linstow gives of the cuticle of 

 Heterakis longecaudata (p. 68) may be mislabeled and belong to this 

 species, as he does not describe any peculiar markings in the hetera- 

 kid). Mouth with 3 Lips bearing a small papilla. Linstow states 

 that in addition to these, papillae are found scattered in an irregular 

 manner over the whole body. 



Male 30 mm. long by 190ju wide. Esophagus 1/11. tail ! 46 of total 

 body length. Nine pairs of caudal papillae (fig. 132), of which 3 

 are preanal and 6 postanal. Both spicules very long, the one 2.1 

 mm., the other 1.1) mm. long. 



Female apparently unknown, as not described.
