Unfortunately the label of these specimens has been lost, but I know that 
they came either from off the Konkan coast or from off the Laccadives, and 
from a depth not less than 444 fms. 
This species is characterized by the remarkably uniform size of the septa. 
Named in memory of Captain Moresby of the Indian Navy, a marine 
surveyor whose work in these seas is well known through Darwin’s “Coral 
Reefs.”

A small, undoubtedly “living,” branch, together with a dead one, was 
dredged with numerous living branches of the last-mentioned species, off the 
Malabar coast, probably at 444 fathoms, or at a still greater depth. 
This coral had also been dredged off Madras, at 88 fms. 
Our specimens are identical with some in the Indian Museum from 
Japan. 
Distribution: Japan and Moluccas, Bay of Bengal, Malabar Sea.

This species appears to be a Cyathohelia although some of its branches do 
not exhibit the characteristic gemmation of that genus, and although the ¢wo 
crowns of pali are not distinctly recognizable and the septa are fewer. 
In typical branches the gemmation is regularly dichotomous, and leaves 
the parent calice immersed between, but not very much compressed by, the 
bases of its pair of successors. 
The surface of the branches is snow-white and perfectly smooth to the 
naked eye, though under a lens it is finely frosted and sometimes, but not 
always, finely striated. 
The free cups are circular and moderately deep and have an edge slightly 
scallopped by the moderately exsert septa, which do not much fill up the fossa. 
The septa are in six systems and three cycles. Those of the first two 
eycles are equal in size, and opposite to each one of them is, generally, a large 
twisted foliaceous palus. But the pali are very irregular in size, and one or 
two are occasionally absent. The septa of the third cycle are small and in-
