lateral by Travassos and Lane. This is closely followed by a ven- 

 tral pair and this in turn by a lateral pair. Towards the tail end, 

 in a secondary expansion of the caudal alae, are 2 pairs of lateral 

 papillae with a pair of ventral papillae occupying variable posi- 

 tions between them; it is this posterior group that seems most 

 characteristic of the species and distinguishes it in particular from 

 A. galli, in which the ventral pair of papillae is lacking. Cloacal 

 aperture 540/* from tip of tail. Spicules equal and narrow, with 

 slightly enlarged rounded points, 1.6 to 2.4 mm. long. 



Female 60 to 95 mm. long. Vulva about at union of anterior and 

 middle thirds of body length (in middle of body (A. hamia), accord- 

 ing to Lane (A,, hamia) and to Schwartz). Tail 1.08 mm. long;

according to Lane, that of A. hamia is 1.3 mm. long and there are 

 lateral papillae 500m from the tip. Eggs elliptical, 80m long by 50m 

 wide; in A. hamia Lane says they are thick-shelled and 65m long 

 by 40m wide. 



Life history. — Probably similar to that of A. galli (p. 82). 



Distribution. — North America (United States), South America 

 (Brazil), Asia (Turkestan and India (A. hamia)), Africa (Belgian 

 Congo and Zanzibar) and, according to Skrjabin, Europe. As noted 

 previously (p. 82) it is this species and not A. galli which is com- 

 monly found in domestic birds in the United States.
