by him in 1858 near Molde and since found near Bergen and in 

 the Hardangerfjord. Dr. Danielssen from the first regarded it as a 

 distinct species, but his colleague in the production of the ' Fauna 

 littoralis Norvegia?,' the late Dr. J. Kpren, came to the conclusion 

 that it was identical with Gosse's Oerianthus Lloydii. Continued 

 observation, however, has convinced Dr. Danielssen that the Nor- 

 wegian species is quite distinct from C, Lloydii, and he now describes 

 and figures it, with details, under the above name. As the two 

 forms are very nearly allied it seems quite possible that 0. borealis 

 may occur upon our own coasts and have been hitherto regarded as 

 belonging to C. Lloydii, so that a note of the characters attributed 

 to the new species may be acceptable to some of our readers. Dr. 

 Danielssen describes it as having an elongate cylindrical body, 3<> 

 millim. long, and living in a tube of about double that length and 

 closed at the bottom. The body of the animal is a little wider in 

 the middle, and tapers off especially towards the posterior extremity, 

 where there is a round aperture. The upper margin, which is 

 finely corrugated longitudinally, can be drawn over the buccal disk 

 and tentacles so as to conceal them almost entirely. The buccal 

 disk is somewhat depressed, and the oblong central mouth has two 

 mouth-angles. The marginal tentacles are in two alternating rows, 

 18-27 in each row ; they are not retractile, nor are the buccal 

 tentacles, which are of the same number and arranged in two 

 irregular series. The body is yellowish white, with the disk rather 

 darker, and the tentacles have a brownish tinge. 



The second article is a continuation of Mr. James A. Grieg's 

 account of the results of his investigations of the fauna of the West- 

 land fjords, in which he enumerates the Echinoderms, Annelides, 

 Polyzoa, Myzostomida, and Pycnogonida obtained by him in the 

 Mosterfjord. These notices of animal forms occurring off the shores 

 of a country so near to us as Norway must be of considerable 

 interest to British zoologists, and their value is enhanced by the 

 statements with regard to mode of occurrence which are given 

 in connexion with several of the species. In this paper Mr. Grieg 

 also describes a new species of the Holothurian genus Cucumaria, 

 under the name of C. mosterensis, which is figured with details in an 

 accompanying plate. 



In another article Mr. Grieg describes examples of the White- 

 beaked Dolphin (Lagerwrhynchus albirostris) captured in April last 

 at Bildoen. Mr. Grieg gives a full description of the species with 

 very carefully prepared tables of measurements of the various parts 

 of the skulls and skeletons of individuals captured. A good figure 

 is given of a female specimen. 



Another zoological paper is that by Mr. G. Armauer Hansen on 

 Neomenia, Proneomenia, and Chcetodermo , in which the nomencla- 

 ture and characters of those three Gephyrean genera are discussed 

 and illustrated in a plate. Of Neomenia the author cites three 

 species, namely, N. carinata, affinis, and Dalyelli: the last a form 

 noticed by Dalyell under the name of " Vermiculus crassus ; " the 

 first originally named Solenopus nitidirfus by Sars, but never
