greater than that of the gullet. This appears to represent 

 a cardia, an organ which is stated to be rare in species of 

 Filaria. The intestine passes back as a fairly wide tube. 

 Its course may be straight, sinuous or at times looped. 

 The anus in the male is situated at about 0*72 mm. from 

 posterior extremity. The excretory system was not 

 recognised. The nerve ring is a well-defined structure 

 surrounding the oesophagus at about 0*18 mm. from the 

 anterior end. The dermis of the body wall is relatively 

 thick when compared with the muscle cells. 



Special Characters of the Male.— The male worm, as 

 mentioned above, is much thinner than the female and has 

 a more delicate cuticular ornamentation. There is no 

 depression of the body surface corresponding to that in the 

 region of the vulva in the female. There are two unequal 

 spicules. The larger is arcuate with a twisted stem and a 

 sharp pointed extremity. The proximal end is enlarged as 

 is usually the case. The length is about 0*197 mm. The 

 second spicule is 0*082 mm. long (indicated by dotted lines 

 in fig. 3), its distal termination being swollen and rounded. 

 The cloaca is situated on a median prominence about 0*065 

 mm. from the end of the parasite. On each side of it are 

 four blunt prominent pnpilhe which aiv peri-anal in position. 

 There is a pair just near the caudal extremity, and at about 

 midway between these and the hindmost of the peri-anal 

 there is situated another pair. There is thus a total of six 

 pairs. At t he caudal extremity is a slight rounded bilobed 

 structure which perhaps represents still another pair of 



like that figured by Parsons 1 for Filuv'ui volvulus. The 

 gonad is double. 



Special Characters of the Female. -Tin- vulva is situated 

 in a shallow depression at about 0*8 mm. from the anterior
