On the Littoral Fauna of the Anglo-Norman Islands. 229 XXV. — Contributions to the Study of the Littoral Fauna of the Anglo-Norman Islands {Jersey^ Guernsey, Herm, and 8arh). Bj Dr. R. Kcehler*. [Plate XI.] The Anglo-Norman islands (Channel Islands) are situated a few leagues from the French coast, to the west of the penin-sula of the Cotentin. The most important of these are Guernsey, Jersey, and Alderney (Aurigny), to which may be added three smaller islands, situated not far from Guernsey — Sark, Herm, and Jethou, the Ecrehous to the east of Jersey, and a number of small islets grouped around Guernsey and which are inhabited. I have passed two successive summers, in 1884 and 1885, in the Channel Islands. The first year I resided in Jersey and studied the fauna of that island, and, to a less extent, that of Guernsey and Sark. The following year I took up my abode in Guernsey, to continue the investigations vvhich had only been sketched out the preceding year and to thoroughly explore Herm, which I was unable to visit in 1884. The observations of which I shall give an account in this memoir are chiefly the result of researches carried on upon the shores at low water. During my first sojourn in the English islands in 1884 I made several dredgings and pelagic fishings, but in 1885 I preferred to devote all my time to researches on the shore ; moreover I was unable to find in Guernsey a fisherman who possessed a dredge fulfilling my requirements. I have, however, carefully noted some species brought to me by the fishermen, which were obtained by dredgings made off the south-east point of Guernsey. I did not wish (and indeed it would have been impossible for me) to pay attention to all the groups of animals which together constitute the marine fauna of Jersey. In the first place I discarded the fishes. Their study, and especially their preservation, necessitate a quantity of encumbering mate-rials with which 1 could not tliink of loading myself. I have also paid comparatively little attention to the Mollusca. A list of the species found at Jersey has been published by M. Duprey in two notes inserted in the 'Annals and Magazine of Natural History.' I therefore omitted entirely the study of the Mol-lusca of Jersey, judging that I should not find anything to do after the researches of M. Duprey, who has for a very * Translated by W. S.
