Figure 104. — Hartmeyeria chinensis, new species: a, b, lateral and undersides of the spinule 

 from the inner surface of basal portion of siphons, highly magnified; c, spinule from the 

 inner surface of distal part of siphons, highly magnified. 



one to three whitish finger-shaped protuberances (fig. 103i). Margin 

 of anus clearly cut into 16-20 lobules. Left gonad located obliquely 

 across dorsal branch of intestinal loop, while right one situated along 

 dorsal margin of renal sac, which is fairly elongated and extremely 

 thin-walled. Openings of vas deferens rather numerous, 10 on the 

 right, 11 on the left gonad in the 23 mm. long individual examined 

 (fig. 103i). 



Remarks. — It is uncertain whether the absence of rhizom is a 

 natural characteristic or a result of somewhat rough treatment under 

 which the animals were collected. Superficially the present new 

 species closely resembles TI. orientalis Oka from Japanese waters, but 

 they differ distinctly in arrangement of muscles and in the appear- 

 ance of the liver, anal margin, and spinules on the inner surfaces 

 of siphons.
