Internal Anatomy : Septum 5/6 is somewhal thickened, 6/7 considerably, 7/8, 

 8/9 and 9/10 much thickened, considering the size of the worm ; 10/11 to 13/14 are 

 also somewhat strengthened. 



There is a rudimentary gizzard in segment vi, of fair size, barrel-shaped, but 

 soft; it appears as shining longitudinal bundles of muscular fibres. The large lobes 

 of flie pharyngeal glands occupy much space in segment v. There are no calciferous 

 glands. The intestine begins in xiv. 



The last heart is in xii. 



The excretory syst em is micronephridial. Behind the genital region there are 

 three nephridia on each side in each segment, with the form of flattened coils (not the 

 flattened plate-like organs of Dichogaster, where similarly there are only a few 

 nephridia on each side in each segment). In front of the prostatic region there are 

 even fewer, perhaps only one on each side in some segments ( ? ). 



Testes and funnels are free in segments x and xi (judged from the .flocculent 

 masses in these segments, which pass deep in the segments into the iridescent covering 

 of the funnels ; testes were not separately identified). Seminal vesicles are present 

 only in xii, as rounded masses which may meet dorsally over the alimentary canal. 



The prostates are two pairs, tubular, of fair length and sometimes extending 

 beyond their own segment, bent several times. The duct is much thinner than the 

 glandular portion, almost straight, and shining. 



Ovaries arc present in segment xiii. and ovisacs in xiv. 



The spermathecal ampulla is an exceedingly irregular and deeply lobed sac 

 (fig. 46) ; the duct is as long as or longer than the ampulla, but relatively narrow, of 

 flu 1 same diameter throughout, firm and shining. What I think is the diverticulum 

 (since in one specimen it contained iridescent spermatozoa, which the main sac never 

 does) is a saccule attached to the ental end of the duct, much resembling one of the 

 lobes into which the ampulla is incised. 



Two spermathecae were found on the right side in segment viii, opening side by 

 side j lliis is presumably an individual anomaly. 



The penial setae arc bent into about two-fifths of a circle, and measure across the 

 bend '7 mm. : the thickness at the middle is 12/«, but at the proximal end 20m, The 

 shaft tapers gently towards the distal end, which does not quite continue the direction 

 of the curve, but is slightly bent in the contrary direction. The tip is somewhat 

 wavy, and ends in a fairly sharp point. The ornamentation consists of a number of 

 irregular rings of small teeth on the distal portion of the shaft, the terminal portion 

 however being smooth. 



Remarks : -The absence of calciferous glands, with the small number of nephridia 

 per segment, allies this form \o the group of pall id us and bishainbari.
