320 Records of the Indian Museum. [VOL Sc: 
The ovaries and their funnels have the usual position. 
The spermathecae, in vii and viii, are simple oval sacs sessile 
by one of their extremities on the bodywall, and without distin- 
guishable duct. 
The penial setae (fig. 13) are of very simple form. The tip is 
blunt and very slightly curved, and the proximal end of the shaft 
is bent at an obtuse angle; otherwise the shaft is straight. There 
are faint sculpturings near the tip,—fine points, forming irregular 
and much broken circles round the terminal portion of the shaft; 
there are about a dozen such circles in all. In length the setae 
are ‘63 mm., and in diameter at the middle of the shaft 24, . 
Remarks.—The species which the present form most resembles is 
Pertonyx aborensis, Stephenson (23). Besides minor differences, the 
fusion of the vesiculae seminales, and the presence of penial setae 
in the present specimen, suffice to distinguish the two. 
Perionyx inornatus, sp. nov. 
(Plate xxx, fig. 14). 
Sandakphu, Darjiling district, 12000 ft., E. Himalayas, 14-iv-1g10 
(C. W. Beebe). A single specimen. 
External Characters.—Length 96 mm.; breadth5 mm. Colour 
yellowish brown. Segments 124. The specimen was not easy to 
examine, owing perhaps to the method of preservation, which 
besides contracting it had rendered it hard and brittle. 
Prostomium apparently proepilobous. 
Dorsal pores from furrow 6/7. 
The setal rings show no ventral break, nor any dorsal break 
in front of the genital region; behind this, however, there is a small 
and irregular dorsal break. ‘The setae are set closer together ven- 
trally than dorsally. The following numbers were counted :—56/v, 
70/ix, 75/xil, 83/xix. 
No clitellum was distinguishable. 
There is no apparent modification of the skin over the region 
of the male apertures. On segment xviii there is present a median 
shallow depression, with shelving sides, oval in shape with its long 
axis transverse. The whole extent of the depression is about one- 
ninth of the circumference, and the small male apertures are on its 
sides, about in line with the setal interval de. 
The female apertures were not seen. 
The spermathecal pores are near the middle line in furrows 
6/7 and 7/8; the distance between them is about equal to that 
between the male pores. 
Internal Anatomy.—Septum 5/6 is thin, 6/7 and 7/8 slightly. 
8/9 and 9/10 moderately thickened, ro/11, 11/12, and 12/13 again 
slightly thickened. 
The gizzard is in segment v, of squarish outline and consider- 
able size, but soft and with comparatively thin walls, 7.c. in some 
degree rudimentary. The intestine begins in xiv. 
The last hearts are in xii.
