1915.] J. STEPHENSON : Indian Oligochaeta. 77 
The penial setae, of the form described by Michaelsen, are here considerably 
shorter than in his specimens,—measured across the curve they are just under 3 mm. 
Remarks.—With regard to the position of the gizzard (said in the original des- 
cription to be in vii) Michaelsen (12) has already suspected that it might prove 
to be in vi. 
Megascolex escherichi, Mich. var. papillifer, var. nov. 
(Plate VIII, fig. 16.) 
Horton Plains, Ceylon, 7000 ft.; under stones and logs; Dec., 1913 (S. W. Kemp). Numerous 
specimens. 
- Same locality, date and collector; in jungle paths. Four specimens. 
This interesting species has recently been described by Michaelsen (12). There 
can, I think, be no doubt about the specific identification of the present specimens; 
but the presence of genital papillae, and especially the coexistence of ‘‘ megane- 
phridia’’ along with micronephridia, give them a peculiar interest. I append a 
description of the external characters, together with a few remarks on points in the 
internal anatomy. 
External characters.—Length 55 mm., max. diameter 3 mm.; colour dorsally 
a brownish purple, deepest anteriorly, but of varying depth in different specimens, 
grey ventrally ; position of setal ring marked by a whiteline. Body slightly flattened 
dorso-ventrally. Segments 121. 
Prostomium epilobous 4, the dorsal process (tongue) cut off or not by a trans- 
verse groove behind ; segment i divided ventrally by a longitudinal cleft. 
First dorsal pore in 5/6 ; none seen anterior to 11/12 in another specimen. 
The setal ring presents a mid-dorsal break,—zz=2-2}yz. Ventrally the ring is 
almost closed, aa=14ab. The numbers counted were:—v/36, xiii/40, xix/40, more 
posteriorly 44. 
Clitellum xiv—xvii=4, distinguishable only by being of a redder tinge. 
The male pores are small, close together on xviii, in the middle of an oval slightly 
raised whitish patch (fig. 16) which encroaches forwards on xvii, but not always 
backwards on xix. The surface of the patch may be marked by one or more of the 
following grooves :—a transverse , near its anterior border, a similar groove near its 
posterior border, and a median longitudinal joining the two former. 
Female apertures as in the original description. 
Spermathecal apertures minute, quite close to the middle line, in 6/7, 7/8 and 8/0. 
A genital papilla may or may not be present in groove 19/20; or occasionally 
two, in 19/20 and 20/21. The papillae are small, transversely oval, whitish, and 
situated rather to one side of the middle line, never mid-ventrally. Of twenty-four 
specimens examined, there were no papillae in 5 (of these perhaps two were not 
fully mature), there was one on the left side in 9, one on the right in 9, two both 
on the right (v. fig. 16) in one. 
Internal char acters.—The gizzard is partly in segment vi, septum 6/7 being attached 
round its anterior part, behind its anterior third. ‘The gizzard appeared to me rather 
soft, but not in any degree rudimentary.
