Stylaria kempi, sp. nov. 
(Plate xxx, fig. 2). 
Bhim Tal, 4450 ft.. Kumaon, W. Himalayas, 2—10-v-1g11 (S. W. 
Kemp). ‘Two specimens. 
Length 2:25-4mm. Noeyes. The prostomium forms a long 
narrow proboscis, in length equal to three times the diameter of 
the body. n=25. 
The anterior ventral setae (fig. 2) (segments ii-v) are 120 in 
length; the terminal prongs are very unequal, the distal being 
large, the proximal veryshort. The nodulus is markedly proximal, 
the relation between proximal and distal portions of the shaft 
being 1:2. The distal curve of the seta is slight, the shaft being 
straight almost to its end; there is a slight bending forwards 
(in the direction towards which the prongs point) of the shaft at 
the nodulus. The number in a bundle is six or fewer. 
The posterior ventral setae (vi backwards) are 96-100 in 
length. The proximal prong is perhaps even more rudimentary 
than in the more anterior setae. The nodulus is still proximal, 
but not so markedly, the relation of the two parts of the shaft 
being 2:3. There isa slight ‘kinking’ of the shaft at the nodulus 
here also. The number in a bundle is six or seven. 
The dorsal setae begin in segment vi. In each bundle there is 
a long hair 450-600n, i.e. twice, three times, or even more than 
three times as long as the diameter of the body. In addition to 
the long hair there are others, shorter, equal in length to the 
diameter of the body or less, 200% down to 120» or less, even 80y. 
A third component of the dorsal bundles exists in the form of two 
or three short, fine, and sharp needles, 4or in length; these do not 
appear to differ (except in length) from the shortest of the hairs, 
and may be merely a younger stage of the latter. It is possible 
also that the shorter hairs are merely a stage in the growth of the 
long hair; certainly they are much thinner, but then they naturally 
would be thinner if they represent only the distal portion of the 
fully formed long seta. ‘There is apparently however only one 
long hair per bundle, which seems to mark it out as a. special 
structure. 
There are no septal glands. ‘The gut may show either a 
sudden and considerable widening, or only a slight dilatation, in 
segments viii and ix, taking up both these segments. 
Remarks.—The chief difference between this species and the 
common S. lacustris is the absence of eyes in the present case. 
This would seem to be an absolute distinction, since Piguet (17) 
states that he has seen hundreds of specimens of S. lacustris, but 
none without eyes. 
Piguet also describes a pigmented band encircling the gut 
(not always marked) in each segment after the sixth in S. lacustris ; 
I did not observe this in the present specimens. Michaelsen (13)
