436 Records of the Indian Museum. [Voi,. XXIV, 



The spermathecal apertures are in furrows 7/8 and 8/9, near 

 together, about in line with the third seta on each side. 



There are no other genital marks. 



Internal Anatomy : — Septa 6/7 and 7/8 are slightly thickened. 

 8/9 and 9/10 moderately so. 



The gizzard is vestigial, in segment v. There are no calci- 

 ferous glands ; but the oesophagus is dark in colour, with trans- 

 verse vascular striations, in segms. xii and xiii. The intestine 

 begins to widen out behind the prostates. 



The last heart is in segm. xiii. 



The nephridia all end in the same line. 



Testes and funnels are free in segms. x and xi. Seminal 

 vesicles are present in segms. xi and xii ; they fill the length of 

 their segments, and are apposed to their fellows in the middorsal 

 line. 



Prostates are present in segm. xviii, but are very small ; the 

 duct is stout in relation to the size of the gland, is muscular and 

 shining, and almost straight. 



Ovaries and funnels are present in segm. xiii. 



The spermathecae, in segms. viii and ix, are small elongated 

 sacs, with no distinguishable duct, and a minute wartlike diverti- 

 culum near their base (not present in all). 



There are no penial setae. 



Subfamily OCTOCHAETINAE. 

 Genus Octochaetus Bedd. 

 Octochaetus beatrix Bedd. 

 Bombay. Coll. Prof. J. P. Mullan. 



The original description of this species was given by Beddard 

 (2) in 1902. In 1914 I described as a new species a worm which 

 I called Octochaetus dasi (8), but I now believe that this is identi- 

 cal with Beddard's species. The following notes fill in a few gaps 

 in our knowledge. 



Prostomium epilobous \ ; the tongue is very narrow, and not 

 cut off behind. 



The setae in the present specimen were spaced as follows : — 

 in the middle of the body, and behind the genital region a&=i/3 

 ««=2/5 Jc=2/3 cd ; on segm. ix ab=\ aa=% bc=2/3 cd ; dd=2/$ 

 of the circumference. 



The male area is a somewhat quadrilateral depression with 

 rounded angles, small, rather deep, midventrally on segms. xvii- 

 xix ; it indents the posterior border of the clitellum, and is com- 

 prised within the lines of setae a. Small papillae are seen in 

 the line of b, on the borders of the depression, in segms. xviii 

 and xix, perhaps the porophores of the male and posterior prosta- 

 tic apertures respectively ; there is not distinct papilia or aperture 

 on xvii. No seminal grooves were visible.
