PERICHETA STUARTI, Sp. 0. 
The clitellum extends over somites xiv., xv., and xvi.; it is very 
well marked. 
There are two pairs of male pores in somites xvii. and xix., respec- 
tively ; these are all four placed upon a whitish, slightly depressed 
patch, which thus extends over the greater portion of somite xvii., the 
whole of somite xviii. and the greater portion of somite xix. 
Connected with each of these pores is a large coiled prostatic gland, 
which extends backwards in each case through some 8 or 9 somites. 
There is a single median oviducal pore in the anterior portion of 
somite xiv. 
There are two pairs of spermathecee, situated in somites vii. and 
viii., respectively. They do not possess any appendages, but 
present a sort of frilled appearance around the base. 
The gizzard is situated in somite x. 
In somites xxiii._xxvi. (?) there are four pairs of special diverticula 
on the dorso-lateral portions of the intestine. 
I have not observed any nephridia. 
There are about 52 setze in each somite arranged with small 
dorsal and ventral gaps; sete are present on the clitellum. 
There are no special seta in somite xviii., but in the anterior 
portion of somite viii. (¢. e. between the anterior and posterior pair 
of spermathecze) there are two groups of large modified setze. Where 
these project on the surface, there is a papilla which in some speci- 
mens becomes very well marked. 
Length 148 millim., cireumference 15 mm.; number of somites 111. 
Hab. Yercaud, at an elevation of about 5000 feet, and also down 
the ghaut as low as Salem (1000 ft.). I have specimens from 
Salem. 
This is an exceedingly common worm in this region. It occurs in 
dry ground, and often under large stones. 
PERICHETA BURLIARENSIS, Sp. nD. 
The clitellum extends over somites xiv., xv., Xvi., and xvii., and 
is well marked. 
The male pores are situated in somite xviii. ; segments Xix., Xx., 
xxi., and xxii. bear papillee (apertures ?). 
The oviducts open in somite xiv. by a single median pore. 
The spermathecee are placed in somites vi., vii., vili., and ix. ; they 
present a single appendage. I am unable at present to say anything 
about nephridia. 
The gizzard is situated in somite x. There are a single pair of 
intestinal czeca in somite xxvi., reaching forwards to somite xxiv. 
There are 38 to 40 setee per somite. Setze are entirely absent from 
the clitellum. I find no special setee in somite xviii., but there are two 
pairs of groups of enlarged setee in somites vii. and viii., respectively. 
There is a large ventral gap, especially in the somites immediately 
following the male pores, where the most ventrally placed setee are 
larger than the others.
