668 DR. A. G. BOURNE ON INDIAN EARTHWORMS. [Dec. 21 
Length 100 millim., circumference 9 mm. ; number of somites 123. 
Hab. Burliar, 2000-3000 ft. 
PERICHATA HULIKALENSIS, Sp. nN. 
The clitellum extends over somites xiv., xv., xvi., and xvil., and 
is well marked. 
The male pores are situated in somite xviii., and are rather near 
together, and placed upon slight papille. 
The oviducts open by a single median pore in somite xiv. 
The spermathece are placed in somites vii. and viil.; they present 
a single filiform appendage. 
No nephridia were observed. 
I believe intestinal diverticula are present in the usual position. 
There are about 42 sete per somite. The ventral gap is equal to 
4 ordinary gaps, and the dorsal gap to 7 ordinary gaps. Sete are 
present on the clitellum. 
No special setze were observed. 
Length 200 millim., circumference 9 mm. ; number of somites 209. 
Hab. Hulikal-drug, Nilgiris. Elevation about 6000 ft. 
PERICHETA MIRABILIS, sp, 0. 
The clitellum extends over somites xiv., xv., and xvi., and is well 
marked. 
The male pores are widely separated, and situated on low papille 
in somite Xviii. 
The oviducts open by a median pore in somite xiv. 
The spermathece are situated in somites vi., vii., vill., and ix.; they 
present a single appendage. They open, as is usually the case, exactly 
between the somite in which they lie and the preceding somite. 
The gizzard is situated in somite x. 
Intestinal czeca are present in somite xxvi., and run forwards. 
Nephridia seem to be present in certain anterior somites only, as 
in P. gracilis. 
There are four pairs of groups of small nephridia in the posterior 
portions of somites v., vi., vil., and vill., respectively, and these open 
on minute circular papille which are placed in diamond-shaped 
depressions lying in the posterior portion of the somites, in which 
the nephridial groups lie, and just ventrad of the nephridiopore 
which lies between each of the somites and the succeeding somite. 
There are further two pairs of groups of nephridia lying in somites 
vii. and viii., respectively, and opening on similar papille placed 
ventrad of those above described, and just anterior to the seta-ring 
in each somite. The further details with regard to this remarkable 
arrangement I hope to work out on a future occasion. I may 
mention here that I at first mistook these nephridiopore-bearing 
papillee for the pores of the spermathecz, and it is quite possible 
that previous observers have done the same thing in other species of 
Pericheta. It needs the most careful and repeated observation to make 
out the exact arrangement. There 39 sete per somite, with no gap 
either dorsally or ventrally. It is always possible, however, to re- 
cognize the median ventral or dorsal lines, as both ventral and dorsal
