17. Filaria volvulus, R. Leuckart, 1893. 



The male measures 30 35, the female 60 70 mm. in length. 

 The parasite was first observed by a German medical man in 

 tumours the size of a pigeon's egg, one situated under the scalp, 

 the other on the thorax, of two negroes from the Gold Coast ; 

 Leuckart gave the first description. Another case (Labadie-Lagrave 

 and Deguy) relates to a French soldier who had been in Tonquin 

 for a long time, and had subsequently accompanied the Dahomey 

 expedition. In this case a young female filaria, measuring 25 mm. 

 in length and 15 mm. in breadth, was found in' a lymph vessel 

 within a tumour removed from the shoulder ; blood examinations 

 yielded negative results. A fourth case is mentioned by Prout. 



[The adult male measures 30 35 mm. in length by 0*14 mm. 

 in breadth. The body is white, filiform, attenuated at both ends. 

 The" head is rounded and has a diameter of 0*04 mm. The cuticle 

 is distinctly transversely striated. The mouth is unarmed. The 

 alimentary canal is straight and ends in a subterminal anus. The 

 tail is curved and somewhat flattened on the concave surface. 

 According to Brumpt there are three papillae on each side of the 

 cloaca and three pairs of post-anal papillae. Two unequal spicules 

 may be seen protruding from the cloaca. 



The adult female measures 60 70 mm. in length by 0-36 mm. 

 in breadth. The head is rounded and truncated ; it measures 

 0*04 mm. in diameter. The tail is curved. The striations of the 

 cuticle are not so distinct as in the male. 



The larva measures about 300 JJL in length ; it has no " sheath." 

 The body tapers from about the last fifth of its length and 

 terminates in a sharply pointed tail. At about the anterior fifth 

 of the body there is a gap in the central column of cells (Hanson's- 

 V spot). 



Filaria volvulus is found in peculiar subcutaneous tumours, 

 the size of a pea to that of a pigeon's egg. The same patient 

 may present one or several of these tumours. -The regions of the
