Perich^ta sttjarti, sp. n. 



The clitellum extends over somites xiv., xv., and xvi. ; it is very 

 well marked. 



There are two pairs of male pores in somites xvii. andxix., respec- 

 tively ; these are all four placed upon a whitish, slightly depressed 

 patch, which thus extends over tlie 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 spermathecse, situated in somites vii. and 

 viii., respectively. They do not possess any appendages, bat 

 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 setae in each somite arranged with small 

 dorsal and ventral gaps ; setae are present on the clitellum. 



There are no special setaj in somite xviii., but in the anterior 

 portion of somite viii. (i. e. between the anterior and posterior pair 

 of spermathecte) there are two groups of large modified setae. Where 

 these project on the surface, there is a papilla which in some speci- 

 mens becomes very well marked. 



Length 148 miUim., circumference 15 mm.; number of somites 1 11. 



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. 



Perich^ta burliarensis, sp. n. 



The clitellum extends over somites xiv., xv., xvi., and xvii., and 

 is well marked. 



Tiie male pores are situated in somite xviii. ; segments xix., xx., 

 xxi., and xxii. bear papillae (apertures ?). 



The oviducts open in somite xiv. by a single median pore. 



The sperniathecse are placed in somites vi., vii., viii., 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 caeca in somite xxvi., reaching forwards to somite xxiv. 

 There are 38 to 40 setae per somite. Setae are entirely absent from 

 the clitellum. I find no special setae in somite xviii., but thereare two 

 pairs of groups of enlarged setae 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 setae are 

 larger than the others.
