The list comprises fifty-two species, and a few doubtful 

 specimens remain which may increase the number by one or 

 two. Messrs. Parker and Jones, in their list of Arctic forms 

 give a total of seventy-five, but of these twenty are recorded 

 from the Norwegian coast only, leaving fifty-five for Baffin's 

 Bay south of Smith Sound and Davis Straits. There is fair 

 ground, therefore, for supposing that the number of species 

 of Foraminifera does not suffer any considerable diminution 

 northwards from the Arctic Circle. The species, fifteen in 

 number, marked with an asterisk, in the foregoing table, are 

 those which were found in the sounding made in lat. 83 19' 

 N. at a depth of 7 1 fathoms, and are, except a few Kadiolaria, 

 the unique representatives of the fauna of the sea-bottom at 

 the highest latitude yet attained by explorers. The greatest 

 variety of forms from any single Arctic locality is furnished 

 by mud from 80 fathoms off Cape Frazer, which gives a list 

 of thirty-two species. As already stated, it is not to be 

 supposed that material so limited in quantity has furnished 

 anything like complete details of the fauna ; it may never- 

 theless be of interest to compare the list above enumerated 

 with the columns referring to Baffin's Bay and Davis Straits
