By CHarues Brancu Witson, D.Sc., Pu.D. State Normal School, Westfield, Massachusetts. While the parasitic copepods collected by Mr. Frits Johansen during the Canadian Arctic Expedition do not include any forms new to science, they are still of peculiar scientific interest for two reasons. The first of these has already been stated in connection with both the fresh-water copepods and the free swimming marine forms, namely the fact that they were collected in a region hitherto practically unexplored for such crustaceans. . The present author has reported a few species collected by Alaskan and Siberian fishermen and presented to the United States National Museum; but they were nearly all marine forms and included only a few straggling specimens from the Salmonidx that spawn in fresh water. The present collection supplements these in a very decisive manner and indicates that the genus Salmincola is as well represented in the polar as in temperate regions. In fact we are now justified in concluding that these crustacean parasites are as widely distributed as their fish hosts, and wherever the hosts are found we may well expect to discover also the copepods which infest them.

Among fish remains found in the stomach of Phoca hispida Schreber, captured at Collinson point, Alaska, Station 277. Amother specimen was obtained from the gills of Cottus (Myoxocephalus) scorpioides in Hudson strait, Northwest Territories, September, 1897, by the Diana Expedition under Messrs. Low and Wakeham, and has been identified by the present author. HERPYLLOBIID. Selioides bolbroei Levinsen. Cat. No. 1213. On the back of two Polynoids, Actinoe sarst Kinberg, outer part of Bernard harbour, Dolphin and Union strait, in 3 fathoms of water, Station 41, July 20, 1915. This species was described and figured, but not named, by Dr. R. Horst in 1878, in a paper entitled ‘‘Ueber zwei neue Schmarotzerkrebse” published in Tijdschrift der Nederlandsche Dierkundige Vereeniging, vol. 4, p. 51-55, pl. III. He had but a single female specimen which was taken from the annelid, Polynoe rarispina in the North Sea, and it was ruined before he had completed his examination of it. But the figure of the ventral surface, which he published, leaves no doubt of its identity. On May 15 of the same year (1878) G. M.R. Levinsen published a paper “‘Om nogle parasitiske Krebsdyr, der snylte hos Annelider,’’ Vidensk. Meddel. Natur. Foren., Copenhagen, 1877 (1878), p. 351-380; pl. 6, fig. 1-22. After giving a list of the species previously found upon Annelids, he described a new genus and species, to which he gave the name Selioides bolbroet. The specimens were found upon the Annelid Harmothoe imbricata (Linnzus) on the coast of Greenland, and included both sexes, the females with fully developed egg strings. This is identical with the species figured by Horst and with the present specimens, and is especially noteworthy for two reasons. The swimming legs are all uniramose; those of the first and third pairs are widely separated and close to the lateral margins of the cephalothorax, while the third pair have their basal joints fused across the midline. The egg strings are attached to the sides of the genital segment not by their ends, as is the usual mode, but by the centre of one of the lateral margins. In consequence, as much of the egg string projects forward alongside the thorax as backward alongside the abdomen. Levinsen found upon Polynoe cirrose Pall. a single specimen of a second species of this same genus, whose egg strings possessed the added peculiarity of each being four-lobed. He did not name this species because he had but a single mutilated specimen. The presence of this genus in North West Canada, here recorded, and the occurrence of another species of the genus in the Antarctic ocean, recorded below, suggest that there are likely to be many other new forms, when the Annelids of these regions become better known. In view of the increased interest recently shown in the biology of the Arctic and Antarctic regions, and the noteworthy discoveries which have been made, it does not seem out of place to publish a list of the parasitic copepods which have thus far been reported from these regions. One hundred and forty years ago (1780) Otto Fabricius compiled the first list of this kind, which he called ‘Fauna Grcenlandica,”’ and which, of course, was restricted to the one area mentioned. Fabricius was chaplain at Frederiks- haab, Greenland, for six years, and most of the species he mentioned were obtained from Kvanefjord, which is near by. They included one species referred to the old genus Binoculus, one Cyclops and seven Lerneans. Not one of the entire number is known to-day by the name given to it in Fabricius’ list. Parasitic Copepoda 5L Kroyer was the next to present a “‘Conspectus Crustaceorum Groenlandiz’, in the Naturhistorisk Tidsskrift, vol. 2, 1838-39, p. 249. This portion did not include any copepods, but the second and third portions published in Danske Videns. Selskab. Natur. og Math. Afhand., vol. 7, 1839, included both free swimming and parasitic forms, but only a few species. In 1857 H. Rink published in Copenhagen a volume entitled ‘‘Grd@nland geographisk og statistisk beskrevet,’’ to which various authors contributed. The Natural History supplement contained (p. 28-49) a list of Greenland Crustacea, Annelids and Worms by J.-Th. Reinhardt. In 1875 T. R. Jones published in London a similar “‘ Manual of the Natural History, Geology and Physics of Greenland and the Neighbouring Regions.” In the Appendix, p. 146-165, appeared a list of the Crustacea of Greenland by Chr. Litken, which embraced both free swimming and parasitic forms. And finally, in 1913, K. Stephensen presented in the Meddelelser om Gr¢nland, vol. 22, a ‘‘Conspectus Crustaceorum et Pycnogonidorum Greelandiz,’” which included all that had previously appeared and added many new species. These publications were concerned with the fauna of a single country which had been studied far more often and in greater detail than any other portion of the polar regions. But there have also been the reports of numerous expeditions sent by the various nations of the world either to the North or the South Polar regions. Great Britain, the United States, Norway, Sweden, Denmark and Germany have all taken part in these polar explorations and each has contributed its quota to our knowledge of their fauna and flora. And there have been a few reports on collections made by private individuals or by various museums. From all of these the following list has been compiled. Probably it could be augmented by some of the species found in northern Norway and Sweden, if their geographical distribution were sufficiently known. The Kara Sea and the Murman Coast also suggest promising possibilities, but while the Russian author, Birula, has written several papers upon the Decapod Crustacea from those localities and from Spitzbergen, practically no attention at all has been given to the parasitic copepods. As here given the list includes 28 Lerneopodoida, 20 Monstrilloida, 18 Caligoida, 11 Notodelphyoida and 2 Harpacticoida, all the groups which possess any parasitic forms being represented. There are also two species which cannot be referred to any of the groups with certainty or even probability. The name Lerneopodoida has been substituted for the group designated as Lerneoida by Sars in 1901, in accordance with a suggestion made by Rev. T. R. R. Stebbing in his General Catalogue of South African Crustacea, published in the Annals of the South African Museum, vol. 6, 1910, p. 561. The life history of the genus Lernea as given by the present author in Bulletin U.S. Bureau of Fisheries, vol. 35, 1917, p. 165-198; pl. 6-15, shows conclusively that this genus and the family Lerneide belong to the Caligoida. Hence the name cannot be used to designate another of the groups or divisions. Parasitic CopEPODS FROM PoLaR REGIONS. COPEPODA LERNAOPODOIDA. Chondracanthus cornutus (Miiller).

Hence it cannot stand for a copepod genus, and in its place is suggested the name Aphanodomus, from ’Agdvys hidden and éduvs house, meaning dwelling in secret places, and thus having the same significance as C'rypsidomus.

From a crustacean called by Krgyer Hippolyte aculeata (O. Fabricius), and by Stephensen (1913) Sprrontocaris groenlandica (J. C. Fabricius), on the Greenland coast. With the meager description and the single figure given by Kr@yer it is impossible to locate this species anywhere with certainty. It is even doubtful whether it is a true copepod. Tanypleurus alicornis Steenstrup & Lutken. Tanypleurus alicornis, StrenstRupP, J. & Litken, Cu. “Snyltekrebs og Lernaeer.”’ Kongl. Danske Vidensk. Selsk.

This species was not definitely located by Steenstrup & Liitken, but Bassett- Smith in 1899 placed it in the Chondracanthide. It cannot possibly belong there if the original description is correct, for its attachment apparatus consists of two stalks or arms, separate or fused, joined at the tips with a cirrhose bulla. If these arms correspond to the second maxille the species must belong to the Lernaeopodide, but until this can be determined we must leave it unlocated.
