SYSTEMATIC ACCOUNT. 



Fam. ENCHYTRAEIDAK. 



Gen. Fridcricia, 



W. 88/1. Kierpur, Purneah Dist., Bihar. Sept. 1915. C. Paiva. A 

 single specimen, not fully mature (or over-mature ? ). 



The specimen, diagnosed by the arrangement of the setae as 

 belonging to this genus, but indeterminable as regards species, is 

 mentioned here because the family is rarely met with in India. 



Fam. MONILIGASTRIDAE. 



Gen. Drawida. 

 Drawida kanarensis, sp. nov. 



W. 132/1. Talewadi, near Castle Rock, N. Kanara Dist., Bombay 

 Pres., October 1916. S. Kemp. Three specimens. 



W. 133/1. Castle Rock, N. Kanara Dist., October 1916. S. Kemp. 

 Three specimens. 



External characters : — Length 60-70 mm. ; maximum diameter 

 31^ mm. Colour pale grey, anterior end rather lighter. Segments 

 150-173, all very short behind the clitellum. 



A prostomium is difficult to see in some cases ; in one speci- 

 men it might be called zygolobous, though very small ; in another 

 it is perhaps prolobous. 



Dorsal pores absent. 



The setae are small and closely paired ; aa is slightly less than, 

 or in some regions appears about equal to, cd) dd is approximately 

 equal to four-sevenths of the circumference. 



The limits of the clitellum are rather indefinite, as the altera- 

 tion in the body- wall is not great ; it is saddle-shaped, and extends 

 over x-xiii, and perhaps partly on to xiv (=4 or more). 



The male apertures are in furrow lo/ii, external to the line of 

 setae 6, but considerably nearer to b than to c ; the lips of the groove 

 are swollen here, and in one specimen papillae project from the 

 groove at the site of the apertures. 



The female apertures are in 11/12, in the line h. 



The spermathecal apertures are in groove 7/8, just below c. 



On segment xi are a pair of slightly raised and thickened 

 patches, oval in shape, and one and a half times as broad as long ; 

 they take up nearly the whole length of the segment, and are 

 better marked in front, where they are continuous with the swollen 

 lip bounding the male aperture ; their surface is rather ridged, 

 and they are each limited by a slight groove. They approach 

 fairly near each other towards the middle line, so that the setae ah 

 are on the inner portion of the patch ; the outer border is some 

 distance below c. These patches were not found in the second 

 batch of specimens. 



Internal anatomy. — Septa 5/6 to 8/9 are thickened, especially 

 the first three : the rest are thin.
