II. NOTES ON IRISH WORMS: 1. THE IRISH NEMERTINES WITH A LIST OF THOSE CONTAINED IN THE SCIENCE AND ART MUSEUM, DUBLIN. BY H. LYSTER JAMESON, B.A. (COMMUNICATED BY DR. SCHARFF.) [Read APRIL 25, 1898.] DURING the autumn of 1897, I was engaged for six weeks re-arranging the collection of Irish Worms in the Science and Art Museum, Dublin; and it occurred to me that it might be worth while to publish, in the case of certain groups at least, lists of the species which are contained in the collection, together with as complete an enumeration of previous records as I could collect from the scattered papers which deal with the Irish Fauna. By so doing, it seemed to me that I might render the facts more accessible to other workers, and at the same time make known the hitherto unrecorded examples which the collection contains. With this idea in view, I present the following list of Nemertines, which I hope shortly to follow up with remarks on other groups. The Nemertines in this collection were in part already named. Such as were not already determined, I have been able to identify, with the exception of one or two badly preserved individuals. Under each species, I first enumerate the examples in the Museum; then I give a sketch of the previous Irish records, very doubtful records or uncertain synonyms being omitted. Where the original observer has used an obscure synonym for a well-known species, I give this synonym in brackets ( ). Lastly, I add an account of the general distribution of each species, which I have in great part adopted from Bürger's Monograph (1). The number quoted before the year, in some of the records of specimens in the Museum, refers to the number in the Year Register of the Museum under which the particular individual is entered. The classification adopted is that of Bürger (1). PROTONEMERTINI. Carinella annulata (Montagu) = C. aragoi, Joubin. Examples in Museum, Bantry Bay, 199, 1895; Galway, 1871, Distribution in Ireland,.
