ART. 19 NEMATODES OF GENUS HASTOSPICULUM CHITWOOD 5 



glandular. Vulva approxiiiiately 1 mm. from the anterior extrem- 

 ity. Anus atrophied. 



Host. — Varanus gouldi. 



Location. — Presumably under the peritoneum. 



Distribution. — Not given; probably Australasia. 



Remarks. — Baylis (1930) states that H. gouldi may be a synonym 

 of //. macroyhoXlos Parona, but this seems unlikely since the left 

 spicule of the latter species is very strong as compared with that of 

 H. gouldi. H. gouldi is probably more closely related to H. seti- 

 ferurti and H. onchocercu7)i, but it differs from these two species in 

 the arrangement and number of caudal papillae of the male, length 

 of spicules, length of body, and position of vulva in the female. 



HASTOSPICULUM BIPINNATUM (von Linstow, 1899) Chandler. 1929 

 Plate 3, Figures 4, 5 



Synonym. — FilaHa hipinnata von Linstow, 1899. 



Description. — Hastospiculuin: The head bears two small projec- 

 tions, which may be interpreted as being identical with the lateral 

 liplike organs of H. varani. In both sexes the ends of the body are 

 bluntly rounded, the posterior end tapering a little more than the 

 anterior end. 



Male., 32 mm. long by 590/x wide. Esophagus }{^ and tail i^g, 

 of the body length ; spicules unequal, the larger being 1.01 mm. long, 

 and the smaller 190/* long- Six pairs of caudal papillae, four of 

 them preanal and two postanal. 



Female, 145 mm. long. Vulva ](j.^ of the body length from the 

 anterior end. The embryonated eggs are 65/a long by 47/x wide. 



Host. — Varanus griseu^. 



Location. — Lying loose under the peritoneum of the gut. 



Distribution. — North Africa. 



Remarks. — The data for this description were obtained from von 

 Linstow's (1899) description and figures- He failed to state which 

 of the spicules is the longer, and his figures do not show this; pre- 

 sumably the left is the longer. Skrjabin (1923) pointed out that 

 H. bipinnxitum differed from H. varani in length of body, length of 

 esophagus, size of spicules, and number of preanal papillae. 



HASTOSPICULUM SPINIGERUM Chandler. 1929 

 Plate 1, Figures 5, 6 



Description. — Hastospiculum: An anterior view of the head shows 

 that the subrectangular mouth is surrounded by a cuticular elevation, 

 which is not distinctly epaulettelike in contour, and that paired lat- 

 eral projections arise from the outer margin of this circumoral eleva-
