Koehler pubHshed in 1912 (pp. 252-5) a most useful Hst of Antarctic and sub- 

 Antarctic sea stars in which sixty-seven species are cited. In the foUovv^ing revised Ust 

 there are 1 14 species, even though fifteen names of Koehler's table do not appear in my 

 list. This is reduced to ten, however, by the inclusion of five of Koehler's sub-Antarctic 

 species in my list. Numerous new species, of course, were added by Koehler subsequent 

 to 1912.
