Setaria Javensis, sp. n. 



a. Ceplialic extremity of female. 



b . Caudal extremity of female. 



The anus is distant 320 /^ from the caudal extremity, which 

 tapers gradually and ends in a small knob. The vulva is situated 

 at a point 500 /.t from the anterior end. Ovoviviparous. 

 The embryos hi utero measure 210/x X 7fx. 



In addition to the foregoing species, I recovered another 

 Filariid worm from the abdominal cavity of the same host 

 (Tragulus stanleyanus). This species is evidently very closely 

 related to the genus Setaria, but there are two points of generic 

 importance which separate it from this genus — namely, the struc- 

 ture of the mouth-parts and the presence of bosses irregularly 

 scattered over the cuticle of both sexes ; in other respects it agrees 

 with the generic diagnosis of Setaria, as given by Boulenger 

 (15).
