somite, and in other respects agrees with other species of 
Pericheta. 
In 1883 Mr. F. E. Beddard (36) described a worm to 
which he gave the name Pleurocheta Moseleyi; but 
he has since formed the opinion that it belongs to Templeton’s 
genus Megascolex. It came from Kandy, in Ceylon. Its 
length is 28 inches; there are 260 somites, and about 140 setz 
to each of them. The setz are not in a continuous ring, but 
leave a space, ventrally and dorsally, along the median line; 
their length varies from ‘035 to (066 mm. The clitellum 
occupies somites x111 to xx. No nephridia were observed. 
The spermathece are in somites viii and 1x, with their 
pores in the anterior region. A pair of pores are present 
in each of the somites x11I, Xvil, xvitI, and xtx. Those of 
somite xvi1t belong toa pair of solid glands, which may perhaps 
be prostates, whilst the function of the other pores is quite 
unknown. The seminal reservoirs (“testes”) are paired 
racemose glands in somite x11. Curious kidney-shaped glands 
open into the intestine in its anterior part. 
In 1883 Beddard described (37) some new Earthworms from 
India. 
Pericheta armata (Megascolex, Templeton), from 
Calcutta, has the clitellum in somites xIv, Xv, XVI, XVII. 
There is a narrow break in the ring of sete on the ventral 
surface of the somites. There are three pairs of spermathece 
in somites VII, vill, 1x. In somite xvii, close to the male 
pore, on each side, is a sac containing a number of modified 
spiked sete (as in Acanthodrilus). 
Perionyx M‘Intoshii, from Burmah, is 15 inches long. 
The male pores are not quite so close together as in P. 
excavatus, EH, P. 
In this paper, as also in the same Journal for 1884, he 
discusses Horst’s proposal as to the limitation of the genera 
Pericheta and Megascolex ; he also mentions that his genus 
Pleurochzta is identical with Templeton’s Megascolex. 
A new genus is formed, Typhzus, for an intrachitellian 
worm from Calcutta.
