the posterior extremity. Only one spicule ' appears to be present, and this, from its 

 position, seems to be that of the right side. It is a very broad structure, of charac- 

 teristic shape (fig. 52, s.), and measures 06 mm. in length and 0-07 in width. There 

 are seven pairs of caudal papillae, of which four are preanal. These and the most 

 anterior postanal pair have long peduncles. Their arrangement is best indicated by 

 means of the figure. The posterior lip of the cloacal aperture is tumid. 



Genus Setaria, Viborg, 1795. 

 Setaria, sp. (?). 



Three larvae, taken from "inner surface of cartilage" of a Ja van mouse deer, or 

 chevrotain (probably Tragulus javanicus). 



The worms are of a Filariid type, but are too immature to show recognizable 

 generic characters. 



Subfamily DIPLOTRIAENINAE, Skrjabin, 1916. 

 Genus Diplotriaena, Railliet and Henry, in Henry and O'Zoux, 1909. 

 Diplotriaena tricuspis (Fedchenko, 1874). 

 The collection includes one male specimen belonging to this species, from Blan- 

 ford's laughing-thrush (Trochalopterum méridionale).

For the purpose of confirming the determination of this material, we were fortu- 

 nate in being able to obtain from the Indian Museum five examples from the type 

 series. These, as well as the new material, unfortunately proved to be all females, 

 but we are in a position to add a few details to the description furnished by von 

 Linstow (1906 a). 



The dimensions of the female may be slightly larger than those given by that 

 author, reaching about 43 mm. in length and 1 mm. in thickness. The cuticle, al- 

 though without striatums, is not perfectly smooth, as stated by von Linstow. There 

 are distributed rather irregularly about its surface, especially on the hinder portion 

 of the worm, little longitudinal series of from 2 to 7 very minute, raised, papilla- 

 like structures. There is an appearance of a remarkable structure lining the body- 

 cavity — i.e. within the musculature. This "structure" takes the form of a highly 

 réfringent network, strongly suggestive of a series of longitudinal tubules connected 

 by smaller tubules running transversely. It seems probable, however, that this ap- 

 pearance is an artifact — it may perhaps be the result of the fluid contained in the 



1 In F . macrophallos there are two unequal spicules. Our specimen does not appear to be in any way damaged.
