432 WR M'Andrew on Testaceous Mollusca 
Species in common with the coasts of Europe and Africa. 
he fact of a species having in several instances been obtained 
from only two localities very remote from each other, such as 
Suez eil Japan, is to be attributed to (while it is a proof of) 
the very small amount of knowledge we possess ef the fauna 
of the intervening seas. 
It is not to be supposed that my present list is any near 
approach to a complete catalogue of the Mollusca of the Gulf 
of Suez, much less to that of the Red Sea, to which it forms 
but a small contribution. Up to the very last we never returned 
ay's work without having added several species to 
our collection, and we might probably have long continued to 
do so. It is also remarkable in how many instances we ob- 
tained only one or two examples of a species. 
In addition to the Mollusca, we omitted no opportunity of 
collecting specimens of other branches of zoology. The 
Echinodermata, Crustacea, and Corals, together with the soft 
animals and a few fishes, I presented to the British Museum, 
with a request that any spare duplicates might be forwarded 
to the public museums of Edinburgh and Liverpool. I have 
received no particular account of them ; but Dr. Günther in- 
forms me that among the fishes was a new Hippocampus 
. The sponges I sent to Dr. Bowerbank, on the express con- 
dition that he was to give me a report on them; but this I 
have not yet received. A small sponge which had casually - 
been put into spirits among the soft animals has been described 
by Mr. Carter, and made the type of the new genus (rayella. 
It is interesting as showing some affinity to the family of 
Of Cirripedia the only species met with in abundance was 
Tetraclita porosa. I obtained a few specimens of a species of 
casta, and a curious Pecilasma attached to spines of a Ci- 
daris. Prof. Lovén informs me that it is closely allied to P. 
eburnea of Darwin, which was also found on the spines of an 
Echinoderm in New Guinea. I think that it may very pos- 
sibly prove to be identical. 
N.B. In the following list the localities quoted which are 
ps within the limits of the Gulf of Suez are those from which 
he 1 ive species are recorded to have been previously
