however, be avoided l)y observing the lateral vascular commis- 

 sures. Starting behind in the ovarian segment, xiii, they form a 

 regular series as far forwards at least as the gizzard. Here, 

 however, in many species they stop, as indeed does the dorsal 

 vessel itself; in the present species, for example, the lateral com- 

 missures of viii are situated in front of I, in the normal manner; 

 and just in front of this the dorsal vessel itself comes to an end by 

 dividing into two branches, one to each side, the equivalents of 

 the lateral commissures of vii, which pass laterally round the ali 

 mentary canal. In E. incommodus and E. mohammedi , more primi- 

 tive in this respect, the dorsal vessel is continued on to the pharynx, 

 giving off a complete series of commissures; three pairs of which, 

 situated in the long free space which contains the gizzard, indicate 

 the three segments (vi, vii, viii) of which this is composed. 



Few other points require remark. About the middle of the 

 length of the body, situated dorsally on the intestine and on each 

 side of the longitudinal vessel, is a series of five pairs of alimen- 

 tary glands or diverticula, white in colour, each bilobed, and 

 increasing in size from before backwards. Such diverticula are 

 known in certain other species, and might not improbably be 

 found in all, if looked for. 



In one specimen the penial setae reached the great length 

 of 4*7 mm I could not identify the fine sculpturings near the 

 free end as distinct spines, even with the oil -immersion lens. 



The calcareous glands are of the nature of those described 

 for E. bishambari (v. post.) — lateral projections into the oeso- 

 phagus, which leave a T-shaped lumen in a transverse section of 

 the tube.

This species varies within rather wide Hmits; the chief 

 character which distinguishes it externally is the presence of the 

 large raised circular'or oval papillae in ja. If oval, the long diameter 

 may be transverse or longitudinal ; each papilla may or may not 

 be surrounded by a " wall." 



The male apertures and field show very considerable varia- 

 tions. The pores may appear as two slits ; or the two may be 

 fused into a single slit, transverse or slightly convex backwards or 

 forwards, with slightly puckered margins, extending from between 

 the lines of setae a and b on one side to a corresponding point 

 on the other ; or the separate apertures may be visible near the 

 ends of a common groove, — may indeed be indicated by papillae 

 sunk below the surface in the groove. The Lucknow specimens 

 were different; here the apertures were present as large and 

 conspicuous pits, extending somewhat beyond the lines a and b, 

 i.e. somewhat internal to a and external to & ; a papilla, bearing 

 the penial setae, was seen projecting upwards from the depth of
