tached, one on each side, to lateral processes of the stem, by a joint which 
allows the slightest motion of the water to communicate free vibratory 
oscillations to the nematophore. The inferior nematophore is free, tubular, 
much shorter than the lateral, and arising from a tumescent prominence 
on the stem, slightly below the base of the calycle, is directed upwards 
towards its anterior aspect. The superior nematophore is somewhat 
smaller, but in form and direction corresponds precisely with the inferior, 
it arises on a level with the upper margin of the calycle from the stem, 
which is here quite even and presents no enlargement similar to that which 
marks the origin of the lower nematophore. 
Gonosome.—Unknown. 
Habitat—Off Cape Comorin in 50 fathoms, and off the coast of 
Cheduba Island in 8 to 10 fathoms. 
ENDENDRIUM RAMOSUM (nov. spec.) 
(Plate XII.) 
Trophosome.—Tree-like, stem much and irregularly branched, attain- 
ing a height of 3} or 4 inches, fascicular and rooted by an entangled 
mass of short fibrous filaments, the branchlets are more or less dichoto- 
mously arranged and are all annulated at their origins. 
Gonosome.—Gonophores consisting of clusters of spherical bodies, 
filled with a granular substance. They appear not to be borne on true 
blastostyles, but on the bodies of atrophied hydranths from which the 
tentacles have disappeared. 
Habitat.—In 40 fathoms off Cape Comorin, and very sparingly, in 
from 10 to 70 fathoms, along the coast of Arrakan.

General Features —There are one or two features general to the 
country passed through upon which it would be as well to remark before 
proceeding to note in detail the formations met with during the various 
marches. 
The Glacis—The most remarkable feature to be observed all over 
Southern Afghanistan is the peculiar gradual slope, or g/acis, leading up
