I cannot separate the above, taken at various times at two 

 places in the neighbourhood of Gyantse. The specimens were on 

 the whole well preserved ; several batches were stained a deep 

 brown, probably from the fixing agent employed, and these did not 

 stain well nor give good sections ; the setae of all the batches were 

 very much broken. 



I^ength frequently about 8 mm., specimens 

 ^ up to 20 mm. were met with. Diameter to '4 



// mm. Segments 40 — 64. Clitellum on segments 



xi and xii primarily, spreading to x and xiii and 

 even encroaching a little on ix. Prostomium 

 well marked, bluntly conical, marked off by a 

 distinct groove ; external annul ation distinct, 

 double in the anterior segments according to 

 sketches by Capt. Stewart from life ; this double 

 character is recognizable, though apparently 

 somewhat less distinct, in the preserved speci- 

 mens also. 



Setae dorsal and ventral of same character 

 throughout {v. text-fig. 2), both series beginning 



in segment ii ; they have the usual /-shaped 



curve, are bifid distally, both prongs being of 



// about the same length, the distal prong slenderer 



. // than the proximal ; nodulus indistinct, as a 



slight swelling at the junction of middle and 



Fig. 2.— Seta of distal thirds, just within the body-wall ; length 



Limnodrilus sp. {?). of setsc about "oS mm., but variable ; number 



in bundle usually 4 — 6, occasionally 7. 



The alimentary tube is narrow in .segments i, ii ; pharynx in 



iii ; oesophagus extends to ix, and the tube expands in x to form 



the intestine, if genital products are not present to compress it.
