146 THE VOYAGE OF H.M.S. CHALLENGER. 
pointed towards the base, being more elongated ; and in the smaller calicles the shape of 
the cup is regularly oval. 
From these points it will be seen how extremely close the species is to the Rhodop- 
sammia ovalis, from which it appears to differ in having the larger septa strongly 
eranulated. CYrath 1.0 
Localities.—Samboangan, Philippines, 30 fathoms; Arafura Sea, 49 fathoms. 
Genus 2. Dendrophyllia, Blainville.

Verrill has already pointed out that the genus Cenopsammia cannot be kept distinct 
from Dendrophyllia.’ Professor Duncan has made it a subgenus,” but it seems to me 
that it should be sunk altogether in Dendrophyllia. 
Four species were obtained. 
1. Dendrophyllia axifuga, Milne-Edwards and Haime. 
Dendrophyllia axifuga, Milne-Edwards and Haime, Cor., ii. p. 119. 
A small but well-preserved fragment of this species was obtained. Its very charac- 
teristic mode of growth easily serves to distinguish it from all other species of the genus. 
Locality.—Wednesday Island, Torres Strait, 8 fathoms. 
2. Dendrophyllia conferta, n. sp. (Pl. VII. figs. 2-25). 
Corallum consisting of an elongated main stem which is essentially the parent calicle, 
from which, on all sides, numerous, closely-packed, long calicles arise as branches to form 
a nearly flat-topped clump. The branch-like calicles again bear corresponding calicles 
like branchlets, and, at the upper parts especially, they are crowded with short buds 
which are scattered irregularly around them. The calicles never remain short, but 
elongate to form branches and branchlets. Owing to the close crowding of the 
branch-like calicles, many of them coalesce laterally throughout a greater or less extent of 
their length. The older calicles subcircular, from5 to 8 mm. deep and from 10 to 12 mm. 
wide (the younger ones much less), of nearly the same diameter throughout all their 
leneth, but turbinated at the base, the poimt of junction with the branches being rather 
narrow. The small developing calicles markedly turbinate. Costze very distinct, unequal, 
generally alternately large and small, denticulate. Septa included, thin, almost entire, 
finely and pointedly granulous ; four cycles complete in the larger cups, occasionally
