Little work has been done on the Eotifers of the 

 Arctic region. I have seen only two papers — Bergen dal's 

 (1) on the Kotifera of Greenland, and Bryce's (3) on the 

 Eotifera of Spitzbergen. Bergendal's work is the most 

 extensive on Arctic Eotifers, and has the advantage of con- 

 taining observations on the living animals in their native 

 habitat. He gives a list of 76 species (Bryce says 82), 3 of 

 which he did not name. No less than 26 new species are 

 described, but some of them are insufficiently described, and 

 of doubtful value. 



As Dr Bruce's collections were all made in the islands 

 lying in the north of the eastern hemisphere, only records 

 from this region will be included in the appended Table 

 showing the distribution of the species, so far as known. 



Mr Bryce's paper (3) is the only important one which 

 I have seen dealing with this region. It contains a list 

 of species found in a collection of moss made by Prof. J. W. 

 Gregory on Sir W. Martin Conway's Expedition to Spits- 

 bergen in 1896. Twenty-six species are enumerated. 



Mr Bryce mentions that Goes (6) found 2 species of 

 Gallidina, which he did not name, in Spitsbergen, and that 

 Ehrenberg (5) found Callidina alioium (4) in material col- 

 lected in Spitsbergen in 1867. This would seem to be the 

 only definite record, previous to Bryce's, of a Eotifer from 

 these islands. He further refers to several lists which have 

 been published for Greenland, but does not more specifically 

 refer to any of them but Bergendal's. 



Spitsbergen. 



The available material consisted of about a dozen packets 

 of dried moss, lichens, Selaginella, etc., from Eed Bay, 1899 ; 

 some jars of moss and other plants from Eecherche Bay, 

 1899, preserved in spirit; a large quantity of fresh moss 

 from Prince Charles Foreland, 1906. 



As might be expected from the examination of fresh moss, 

 a much larger number of species was got in Spitsbergen
