8. Filaria magalhaesi, R. Blanchard, 1895. 



Syn. : Filaria bancrofti, v. Linstow, 1892 ; Fil. bancrofti, P. S. de Magalhaes, 

 1892, nee. Cobbold, 1877. 



The male measures 83 mm. in length by 0*28 0-40 mm. in 

 breadth ; the cuticle is firm and delicately striated. The anterior 

 extremity is rounded off, and has no papillae ; the posterior ex- 

 tremity exhibits a double curve, with four pre-anal and four post-anal 

 papillae on each side. These are large and have a villous appear- 

 ance. The mouth is round and unarmed, the pharynx measures 

 i mm. in length, is cylindrical, very muscular, and its hinder part 

 is dilated. The anus is situated 0*11 mm. 

 in front of the posterior border. There are 

 probably two uneven spicules ; one only, how- 

 ever, is known apparently the shorter one 

 the length of which is given as 0*17 

 0*23 mm. 



The female measures 15*5 mm. in length 

 and 0*6 0*8 mm. in breadth; the rings of 

 the cuticle are 0-005 mm - apart (in the 

 male 0*003 mm. apart) ; the anterior ex- 

 tremity is slightly thickened and club-like, 

 the posterior extremity is slender, and termi- 

 nates obtusely ; the lateral ridge is 0*127 mm - 

 in breadth (that of the male 0*007 0*008 

 mm.) ; the anus opens 0*13 mm. in front of 

 the posterior border, the vulva is 2*5 mm. 

 distant from the mouth, the ovaria are two 

 convoluted tubes. The eggs measure 0*038 : 



0*014 mm ; the larvae 0*30 0*35 mm. in length, 0*006 mm. in 

 breadth, with a transversely striated cuticle. 



This species was first discovered at a post mortem, in the left ventricle, 

 by J. P. Figueira de Saboia in Rio de Janeiro, and has been described by 

 P. S. de Magalhaes.
