1915.] J. STEPHENSON : Indian Oligochaeta. 39 
The glandular mass in connection with the ectal end of the spermathecal appara- 
tus is of large size, situated in vii, bifid, each half compact and rounded, with a yellow- 
ish mammillated surface; one half lies higher in the segment, the other ventrally to 
this, the whole bound down to the ventral body-wall and to the septum (7/8) by loose 
areolar tissue. The stalk (atrium) is relatively narrow, and bifurcates, one branch 
going to each half of the mass. Neither the stalk nor its two branches are in any 
sense sacs; the appearance is that of two ducts proceeding one from each half of the 
mammillated glandular mass, which unite to form a common duct; this common 
duct is less than half as long as the glandular part and nowhere dilated. 
.In the second specimen the division of the glandular mass into two lobes was not 
obvious; a division could however be made by means of needles, though not without 
some slight damage to the substance of the gland. But I am quite certain that the 
idea of trying to separate the mass into two parts would never have occurred to any 
one who had no previous knowledge of the species. The duct from the spermathecal 
ampulla entered the lower surface of the mass. 
Remarks.—This species is especially interesting as being the first of the family 
Moniligastridae to be described (E. Perrier, in 1872, from Ceylon). Thetype specimen 
(the only one of the species then known) was re-examined about 1909 by Michaelsen 
(9), who corrected some errors in the original description. Michaelsen himself became 
possessed of other specimens in 1910 (12), and made a few remarks on them, especially 
throwing doubt on the alleged locality of the type. In 1913 he also received from 
Travancore (I4) a badly preserved specimen of a new variety (var. minor). 
The present is therefore the fourth occasion on which specimens of this historic 
species have come to hand. Since it is possible that the present specimens also differ 
sufficiently from the type to constitute a variety (in the prostomium, setal relations, 
position of nephridiopores, and perhaps theform of the atrialglands of the spermathecal 
apparatus), though I do not at present name them as such, I have given an account 
of them at some length. 
Var. gravelyi, var. nov. 
Trichur, 0-300 ft., Cochin State; 1-4-x-1014 (F. H. Gravely). A single specimen. 
External characters —Length 130 mm., diameter 5 mm.; colour on dorsal surface 
an even, beautiful bluish grey, on ventral surface a lighter tint of the same, the lateral 
surfaces different from and sharply marked off from both, of a still lighter drab 
colour; these lateral regions appear thickened, and the intersegmental grooves are 
deeper here than dorsally or ventrally (cf. some spp. of Drawida, ant.). Segments 139. 
Prostomium absent (or invisible). No dorsal pores. 
The setae are minute and very closely paired ; aa and bc appear to be, in general, 
approximately equal. The lateral couples are a little below the middle of the height 
of the lateral lighter-coloured regions (v. sup.) in the anterior part of the body, about 
the middle of their height in the middle, and slightly above in the posterior part of 
body. 
In the first 10 or II segments are a number of small whitish spots, arranged as 
a ring in each segment, each spot slightly raised. These rings at first sight simulate
