Notes on the Crustacea of the Channel Islands. By Canon
A. M. Normay, M.A., D.C.L., LL.D., F.R.S., F.L.S.

[Plates XVI. & XVII.]

THE following publications relate to those Crustacea which
are already recorded from the Channel Islands :—

1. ‘The Channel Islands.’ By D.T. Anstep and R. G, LATHAM.
1862, pp. 231-235. In this work the list of Cirripedia was
supplied by Mr. Collings, that of the Stalk-eyed Crustacea by
Mr. Lukis and Mr. Le Lievre, that of the Isopodaand Amphipoda
by Mr. Le Lievre, and that of the Entomostraca by Mr. Collings.

. ‘Recherches sur la Faune Marine des Iles Anglo-Normandes.’ By
Dr. Rent Ke@urer. 1885.

3. WaLKEr (A. O.) and Hornet (J.). “ Report on the Schizopoda,
Cumacea, Isopoda, and Amphipoda of the Channel Islands,”
Journ. Marine Zoology and Microscopy, vol. ii. 1896, pp. 49-55.

4. THompson (Isaac C.). “Report on the Plankton Copepoda of the
Channel Isles,” Journ. Marine Zoology and Microscopy, Dee. 1897.
I have not seen this paper, but, according to Mr. Sinel, it contains
thirty-one species,

. SineL (JosEpH). “A Contribution to our Knowledge of the
Crustacea of the Channel Islands,” Trans. Guernsey Soc. of Nat.
Sci. 1906.

bo

CY

M. Chevreux collected at Jersey, and sent a list of species
to Messrs. Walker and Hornell tor use in their Catalogue.

THE STALK-EYED CRUSTACEA (EXCEPT SCHIZOPODA).

The following is a full list of the Stalk-eyed Crustacea
which have been recorded. I have found almost all the
species myself, but they are here given on the authority of
(A.) Ansted, (K.) Keebler, (S.) Sinel. Where no letter
follows a name all three writers include the species; where
an initial letter or letters follow the name it must be under-
stood that the writer or writers thus indicated record the
species.

Atter the list I add some notes.on a few species.

Many of the Stalk-eyed Crustacea which are found in
the Channel Islands have been figured by Mr. J. Sinel
in his recently published ‘An Outline of the Natural
History of our Shores,’ 1906 (Swan, Sonnenschein, & Co.).
‘This is a very usetul work tor any person commencing the
study of marine zoology.

I dredged several specimens of

this species near St. Peter’s Port Harbour, Guernsey, last
summer (1906), and A. Hyndmanni and P. cuanensis in the

same neighbourhood,

Galathea dispersa, Bate.

intermedia, Lilljeborg.

Both these species occur off Guernsey, but I have not seen @. neva

from the Channel Isles.

It is possible that the species which has

been recorded as G. neva was really G. dispersa.

History of our Shores, p. 184.

Antennules with three flagella. Rostrum with six teeth ahove,
of which two or three are on the carapace and two below. First
feet didactyle, tolerably strong. Second feet of both sides greatly
lengthened and having the carpus divided into very numerous
jelntlets. Telson with two pairs of dorsal spines. Outer uropod
two-jointed. The colouring is peculiarly characteristic, being
brilliant red, with four pale or white lines extending longitudinally
along the entire length of the animal,

About the year 1859 Mr. J. Sinel procured a specimen of this
beautiful Mediterranean prawn in a lobster-pot at La Rocque,
Jersey. He wrote to ask me what it was, introducing into his
letter a pencil sketch. That sketch undoubtedly represented
Lysmata seticaudata, a most interesting addition to the fauna.
Unfortunately the present existence of this specimen is unknown.
Mr. Sinel tells me that he parted with it to some collector, but he
ciunnot recall to mind who was the recipient. Perhaps this note
may bring to light the possessor of this unique British specimen.

Spirontocaris pusiola, Kréyer. I have a Jersey specimen sent to
me by Mr. Sinel many years ago.

Mr. Sinel, whom I had the pleasure of seeing at Jersey last
year (1906), told me that species of A/ysidea were cauglit at
Jersey and made into a paste called ‘ Chervé,” used in
fishing. He subsequently, in answer to my enquiries, sent
me the following account of this preparation :—

“At present the fishers of ‘Chervé’ have to obtain a
licence trom the chief fishery inspector to enable them to
carry on this very old practice—a very absurd law. ‘lhey
take it both day and night during the spring tides in the
large gravelly pools, among the Zosrera, in the southern bays.

“Tt is taken in large hand-nets, with usually a cross-bar

Crustacea of the Channel Islands, 360

to the handle, so that the fisher’s breast bears on it [see
figure]. The nets are from 3 feet to 4 feet 6 inches across
the wooden (ash) blade which forms the base. ‘lhe best

nets are of horsehair cloth, as used for sieves, but ordinary
linen cheese-cloth is mostly used. At about 18 inches from
the pocket of the net a cane ring with netting of about three
quarters of an inch mesh is inseited across it, so as to prevent
the entrance of larger objects (crabs, shrimps, &c.) among
the Mysids.

“The men usually wade waist-deep, pushing the net before
them for ten minutes or so, when they untie the pocket end
aud empty their catch into their basket.

‘“When the ‘Chervé’ is brought home it is mixed with
a sufficient quantity of coarse salt to preserve it, and then it
is pressed into pans. It forms a pink-coloured compost.
This is sold to mullet-anglers at about four shillings a gallon,
though many anglers obtain a licence and take their own
supply.

‘The favourite places for mullet are not far from the
shore, and high water is the best time for the sport. Tue
angler takes a spoonful of ‘Chervé’ from his tin, uses it as a
ground-bait, and waits awhile. If no mullet turn up in ten
or twenty minutes, he tries another spot or goes home; but
almost invariably a few are soon attracted, to be followed by
a crowd. ‘The ‘Chervé’ tints the water pinkish for some
yards around, and has a strong and not pleasant smell, like
that of boiled prawn or lobster gone bad.

361 Canon A. M. Norman on the

“T am constantly consulted respecting some substitute for
‘Chervé’: crabs and shrimps pounded in a mortar and
salted; ray-fish boiled with sugar; bread soaked in shrimp
soup; cabbage boiled in fat, &c., &e.; but ‘Chervé’ still
holds its own. I have often been astonished when sitting on
a jetty fishing for Labrus &e., and not a mullet in sight for
hours; then down comes a § mulleter,’ who throws in a spoon-
ful of ‘Chervé,’ and in a minute one or two dark forms come
into the field, then more and more, and their silvery sides
flash as they turn about and suck up the ‘ Chervé.’ ”

Mr. Sinel kindly sent me a bottle of “‘Chervé” as taken
from the net. Small pieces of seaweed were mixed with the
animals. Both in numbers and in bulk Macromysis flexuosa
predominated, but Schistomysis spiritus was present in large
numbers, together with afew Strdella armata. No doubt the
admixture of species would vary in different spots and in
different seasons. That the Alysidea were used as bait was
quite a new fact to me, as it probably will be to other
carcinologists.

Metopa sarniensis, sp.n. (Pl. XVII. figs. 1-5.)

A very small species. The antennules and antenne are
subequal in length, and the peduncies of both are quite
smooth and devoid of sete. The first joint of peduncle of
the antennules is stout and equals in length the two following
joints; the flagellum is 8-jointed, the first of these joints
equals in length the last two joints of the peduncle, ‘The
first gnathopod (fig. 1) is remarkable on account of the very
short carpus, which is somewhat triangular; the propo los
equals nearly three times the length of the carpus, it gradually
tapers for the attachment of tne gently curved finger; the
propodos has one seta on the side near the end and a bundle
of three below the attachment of the finger; the finger (fig. 2)
has its distal portion minutely denticulated or serrated ; two
minute setz are on its side above the serrations, and there
are no others.

The second gnathopod (fig, 3) 1s subchelate and resembles
that of many members of the genus in its general form. The
hand widens gradually and slightly from its base, and distally
is abruptly truncated, so that the palm is transverse (tig. 4);
the nail is strong and about equals the transverse palm in
length; it has on its back four sete, and on the palm where
the tip of the finger meets it there is a group of slender spies
and a few sete.

The last pereopods (fig. 5) have the basos outspread behind
into a thin lamina, which 1s devoid of sete or spines; the
meros is expanded behind and projects down to near the
extremity of the carpus.

The first gnathopods are, perhaps, more valuable in this
genus for specific characters than the second, though the
latter are so much the larger. In this species the first
gnathopod is quite different trom that of any other species
of the genus known to me; both the very short carpus and
the serrated tip of the finger are quite exceptional.

the harbour of St. Peter’s Port, Guernsey.

IT am indebted to M. Chevreux for one of the examples of this
interesting species which he procured in Jersey. It is at once
distinguished from our previously known British allies by the dense
clothing of spines and sete on the metasome. It was found by
Catta at Mondarran (Basses-Pyrénées), and has subsequently heen
met with again, but only in the same district, namely at St. Jean
de Lux and near Biarritz, and I have received from Don Ignacio
Bolivar, of the Madrid Museum, specimens which came from San
Scbastian. It is remarkable that this freshwater species should
have been met with at such a place as Jersey.

antennules (Pl. XVII. fig. 6), which is shorter than the first joint of
the flagellum, and of the first gnathopod of the male, for comparison
with the same parts in the following species. This gnathopod has
2-4 toothed processes on the hinder margin of the carpus, which
increase in size distally. Della Valle gives only two such processes.
I figure (Pl. XVII. fig. 7) a gnathopod with three such processes
from Plymouth (as figured by Sars and by Bruzelius, Autonoe
grandimana), and (Pl. XVI. fig. 3) another carpus from Valencia,
Spain, with four processes (as figured by Costa).

Sowinsky has referred a Microdeutopus found in the Black Sea to
this species ; but | cannot reconcile the fig. 6 in his paper of 1891
with the first gnathopod (male) of this species. Nebeski gives an
interesting series of figures illustrative of the gradual change in
form of the gnathopod from the young to the adult.

I last year dredged many specimens of this addition to our fauna
off St. Peters Port, Guernsey.

I have figured some of the most salient features which distinguish
this species from M. gryllotalypa. The secondary appendage of the
antennules is 3—4-jointed and is equal in length to the first three
joints of the flagellum (Pl. XVII. tig. 8). The first gnathopod in the
male has not quite so massive a carpus as in that species (Pl. XVII.
figs. 9 & 10), The carpus is armed with three teeth at the extre-
mity (not passing down the hind margin); these teeth are not in
the same straight line, the innermost and bluntest tooth bends away
from the large central tooth, so that it would appear that the finger
closes down between them. Pl. XVII. fig. 11 represents the distal
portion of the first gnathopod of the female, and Pl. XVI. fig. 4 the
second gnathopod of the male.

OSTRACODA.

The following list contains the species known to me from
the Channel Isies. The freshwater species have not been
sought for, except the very tine Cypris bispinosa, which was
sent to me many yearsago by the late Dr. Lukis of Guernsey.
The species which have the letter 6 after them are inserted
on the authority of Dr.G.S. Brady; the rest have been

found by myself.

CoPEPODA.

In the commencement of this paper it is mentioned that my
late friend Mr. Isaac C. Thompson recorded thirty-one species
of Copepoda from Channel Island plankton. On the Harpac-
ticoida and fish-parasites nothing has been published, and the
few species in my own collection are not worth recording. It
is probable that many minute species new to our fauna will
hereafter be found in what may be expected to prove a
very rich district. It is to be hoped that some naturalist
with good eyes and a steady hand will before long work at
these minims. But very much remains to be done in other
orders, especially among the Sympoda and Ostracoda.
