FILARIA CONJUNCTIVE

may occur that one may have mistaken the remains of the hyaloid 

 artery for a worm, which it resembles in form, size and colour ; 

 the slightest movement of the eye also causes it to move so that 

 it simulates a living organism. 



Accordingly it would be more correct to exclude all the cases known 

 only ophthalmoscopically (Quadri, 1857 ; Fano, 1868 ; Schoeler, 1875 ; Evers- 

 busch, 1891). There then remains only one positive case described by 

 Kiihnt in 1891. In this case it was possible to follow the gradual growth 

 of the parasite for some time, and the worm, which measured only 0*38 

 mm. in length, was finally extracted.

The female only of this species 

 is known. It measures 16 20 

 cm. in length and 0-5 mm. in 

 breadth, and is of a whitish or 

 brownish tint. The cuticle is 

 striated with the exception of 

 a small field surrounding the 

 mouth, which is terminal and 

 has neither papillae nor lips. 

 The oesophagus measures o - 6 

 mm. in length and is tooth- 

 less. The anus is close in 

 front of the rounded posterior 

 extremity, and behind it there

vulva is close behind the oral 



aperture ; the vagina soon divides into two convoluted uteri, 



which are filled with eggs and embryos.
