' Actiniares.' O. Carlgren (pp. 7, 1 pi., 

 1903). 



' Madreporaires.' E. von Marenzeller (pp. 

 8,1 pi.). ' 



Caryophyllia was obtained in latitude Yl° 

 09' S., Desmophyllum in 71° 18', and a new 

 species, Errina gracilis, in 71° 19'. The * Ed- 

 wardsia' stages of actinians were obtained in 

 the tow net as far south as 71° 15', and are 

 described and figvired. 



' Seesterne.' H. Ludwig (pp. 72, 7 pi., 1903). 



A detailed account of the starfishes, with 

 much anatomy and full bibliography. Twenty 

 species are described, eleven of which and one 

 genus (Belgicella) are new and mostly deep- 

 water forms; they were obtained to latitude 

 71° 24' S. There are no bipolar species but 

 eight are found in Magellanic waters. 



' Echinides et Ophiures.' E. Koehleb (pp. 

 42, 8 pL, 1901). 



There are eight echini and fourteen brittle 

 stars. The Antarctic fauna is a special one, 

 not closely related . to Magellanic or Arctic 

 faunas, and has no bipolar species. 



' Brachiopodes.' L. Joubin (pp. 13, 2 pi., 

 1901). 



Two new Rhynchonellce, B. racovitshm and 

 B. gerlachei, and Crania Lecointei n. sp., were 

 obtained south of latitude 70° S. The fauna, 

 as in the case of the echini, seems distinct 

 from any other, but most of the few speci- 

 mens obtained were immature or imperfect. 



' Copepodes.' W. Giesbrecht (pp. 49, 13 

 pL, 1902). 



Some thirty species, of which about half 

 were new, and one new genus, were obtained. 

 Twenty per cent, of the species are common 

 to the Arctic region, or bipolar. This me- 

 moir has involved much labor and is pro- 

 fuse in detail. 



' Acariens libres.' E. Trouessart (pp. 19, 

 2 pL, 1903) ; three Antarctic species; ' Acariens 

 parasites,' Q. Neumann (pp. 6) ; (' Aragnies et 

 faucheurs,' E. Simon (pp. 7). 



These papers are devoted to Magellanic 

 forms, no Antarctic species are cited. 



' Myriapodes.' C. Attems (pp. 5, 1 pi., 1902). 

 Three Magellanic species noted. Includes 

 also ' Collemboles.' V. Willem. 



Six species treated, of which three are Ant- 



arctic, five new genera are proposed. Two of 

 the Antarctic genera have no known close re- 

 latives elsewhere, the other, Isotoma, is cos- 

 mopolite. The Antarctic species have the 

 eyes of reduced size and number, and the 

 author thinks this may be due to the dim light 

 of this cloudy region, and the tendency to 

 adopt for protection a subterranean situs. 



' Seals.' G. E. H. Barrett-Hamilton (pp. 

 20, 1 pi., 1901). 



The species of the region were already 

 known to science though imperfectly. The 

 collections of the expedition, enable the au- 

 thor to add important osteological and other 

 data on the rare Eoss and Weddell seals. 



' Cetacea.' E. Q. Eaeovitza (pp. 142, 4 pi., 

 1902). 



The outfit of the Belgica unfortunately 

 comprised none of the equipment needed for 

 taking large whales, though the region abounds 

 with the humpback, finback and other species. 

 The true right whale (Balcena) is not found 

 in the Antarctic, though it has been errone- 

 ously reported there. The author made the 

 most of his opportunities, however, and ob- 

 tained interesting photographs of the whales 

 in different positions in the water, and many 

 notes, in the discussion of which he settles 

 several doubtful questions and throws light 

 on others. He has inspected the literature 

 of the Antarctic for references to cetacea and 

 has tabulated the results. 



' Amphineures, Gastropodes et Lamelli- 

 branchs,' P. Pelseneer (pp. 85, 9 pi., 1903); 

 ' Cephalopodes,' L. Joubin (pp. 4). 



Professor Pelseneer enumerates a few Ma- 

 gellanic species separately, and divides the 

 Antarctic species into littoral, of which there 

 are three species; fundicolar, of which there 

 are twenty-nine, and pelagic, of which there 

 are five. A few of the species were already 

 known, as abyssal shells, but twenty-seven of 

 the fundicolar species are described as new, 

 and one is given a new generic name. Only 

 four of the species belong to genera not found 

 in the north polar or subtemperate regions, 

 though the species are distinct. Of the two 

 abyssal species previously named, one reaches 

 the Azores, and one Prince Edward Island, in 

 the North Atlantic. There are two forms
