G-ephyrea. — Priapidus caudatus was met with in great abun- 
dance in the sandy mud of a creek at low water ; some of the 
specimens, independently of the long tail, measuring 6 inches in 
length. A great change will require to be made in the descrip- 
tions of Professor E. Forbes, for he does not notice the presence of 
the horny teeth of the proboscis, with their curved central and 
three lateral fangs, or the occurrence of papillae in rows on the 
same organ, or on the body and processes of the tail. 
Besides the common Sipunculiis Bernliardus and S. Johnstoni, a 
new Syrinx (Forbes), Dendrostomum (Quatrefages), was found. 
Dendrostomum Huxley iif new sp. ; from under a stone lying on 
muddy sand. It stretched itself when living to the length of 
7 inches, both extremities being tapered. Body of a uniform dull 
brownish hue, elongated, vermiform, and with the proboscis 
abruptly separated anteriorly by a well-marked shoulder ; instead 
of having a smooth body, as in S. Harveii (Forbes), to which it 
seems most nearly allied, this is everywhere marked by fine 
transverse lines, closely studded with small papillae, just visible 
to the naked eye. The shoulder and base of the proboscis present 
the most conspicuous carunculse, those at the tapering, downy, 
posterior extremity being somewhat less marked, from the absence 
of rugae. The proboscis is about an inch and a quarter in length, 
very rugose at the base, more finely papillated towards the extre- 
mity, near which the papilla sharp like spikes, and towards the 
buccal cirri marked as minute black dots. 
Fishes. — The most conspicuous character in the class of fishes 
(of which thirty-three species were observed) was the abundance 
of the Wrasses that swam in shoals at the margin of the rocks, 
or lurked under the sea-weeds of rock pools. Numerous ex- 
amples of Lepidogaster bimaculatus and Siphonostomus Typhle 
were caught in the laminarian region around the little islands.
