The Antarctic fauna may be divided into cosmopolitan genera, such as Terebru- 
tulina) Hemithyris, and Crania , typical southern forms such as Liothyrdla , Stethothyris, 
and Magellania , and recent northern immigrants such as Macandrevia and probably 
Frieleia. 
SUMMARY OF THE DISTRIBUTION. 
Excluding deep-sea forms, there are few species common to the Southern and 
Northern seas, and in the case of the species of Lingula and of Platidia, the identifications 
of the southern forms are in need of confirmation. The following is a list of the species 
in question : — 
Lingula rostrum (Shaw).—More ion Bay, Australia, and Indian Ocean to 
Japan. 
Lingula Mans Swainson. —Port Jackson, Australia, and China. 
Lingula tumidula Reeve. - -Moreton Bay, Australia, and Philippine Islands. 
Platidia anornioides (Scacchi).—Marion Island, Mediterranean, North Atlantic 
and California. 
Frenulina sanguinolenta (Gmelin). —North-east Australia and Central and 
North Pacific. 
Only one species is common to two of the southern geographical districts, viz. 
Waldkeimia Jcerguelensis Davidson in the Marion Island and Kerguelen groups. All 
the other southern species are confined to single geographical districts, and cases of 
discontinuous distribution, such as are known between the European and American 
coasts of the North Atlantic, are not found in the southern seas,
