39^ Records of the Indian Musettiii. [Vol. XIIT, 



Hoplochaetella bifoveata, sp. nov. 

 (PI. xvii, fig. i8). 



W. 129 I. Talewadi, near Castle Rock, N. Kanara Dist., Bombay Pres., 

 October 1916. S. Kemp. A single specimen. 



External characters. — Length 82 mm. ; diameter at the clitellum, 

 which is bulged, 5^ mm. , behind this 4 mm. Colour light brown 

 above, with a darker middorsal stripe : pale below ; setae on slightly 

 whiter transverse rings. Segments 62 ; possibly the specimen has 

 been damaged, since the last segment is of full size, and is not 

 followed by any zone in which differentiation of new segments is 

 going on. 



Prostomium epilobous -I, very broad, — perhaps somewhat dis- 

 torted, as the buccal cavity is everted. 



Dorsal pores commence from furrow 5/6. 



The middorsal setal interval is irregular in front of the clitel- 

 lum, perhaps because a number of setae have dropped out here 

 and there ; normally zz may be equal to 2yz ; a short distance 

 behind the clitellum the setae become very small and difficult to 

 see on the dorsal surface, but the interval is perhaps about the 

 same. Ventrally they can be better distinguished against the paler 

 background ; aa = 2ab throughout the greater part of the body, 

 = 2lab for some distance behind the clitellum, and is irregular 

 or = 2ab in front of the clitellum. On the whole the setae are 

 more closely set ventrally than laterally or dorsally ; this is best 

 seen behind the middle of the bod3^ The following numbers were 

 counted : 4Q/v, 62/x, 60/xii, ca. 50/xxii. 



The clitellum extends over segments |xiii-xvi = 3^ ; segments 

 xvii and part of xviii are also somewhat modified. The clitellar 

 region is smooth, brownish in colour both dorsally and ventrally, 

 and much swollen ; setae are visible, but no dorsal pores. 



The conspicuous features in the male area (fig. 18) are two 

 large depressed areas, shallow and saucer-like, with only slightly 

 raised rim. These are situated midventrally in the position of 

 grooves 16/17 ^^^ 19/20, but in each case the depression ex- 

 tends further onto the posterior of the two segments (as far as the 

 setal line) than on the anterior. From side to side each takes up 

 approximately a space equal to the interval between the prostatic 

 pores of the same pair ; and in each case the anterior margin of the 

 depression is the better defined, and is rather straighter. 



The prostatic apertures are two pairs of small transversely 

 oval shallow depressions with raised lips, in furrows 17/18 and 

 18/19, iiot very far from the middle line ; the actual openings of 

 the ducts are however invisible, or are perhaps represented by 

 dark dots near the inner and anterior margin of the depressions. 

 It might be more accurate to say that the posterior pair of pits 

 are on the most anterior part of segment xix rather than in groove 

 18/19 ; grooves do not really exist here, and the pits are rather 

 nearer to the setal line of xix than to that of xviii.
