maintained. The third form mentioned above, Asterias vernicina, remains the type of 
Miiller and Troschel’s genus Asteropsis. 
Chorology of the Genus Gymnasteria. 
a, Geographical distribution :— 
Inpran Ocean: One species between the parallels of 30° N. and 30° 8. 
Gymnasteria carinifera from the Red Sea and Mauritius, and 
extending into the Eastern Archipelago and Pacific. 
Eastern ARCHIPELAGO: One (or perhaps two) species between the parallels of 
20° N. and 20° 8. 
Gymnasteria carinifera from Amboina and other islands, and 
extending both into the Indian and Pacific Oceans. Gymnasterva 
biserrata from Larentuka, is in my opinion a young stage of 
Gymnasteria carinifera, or at most a variety which has maintained 
its juvenile characters. 
Pacrric: One (or perhaps two) species between the parallels of 30° N. and 30°, 
Gymnasteria carinifera from New Caledonia, the Fiji Islands, 
the Sandwich Islands and Panama, and extending into the Hastern 
Archipelago and Indian Ocean. Gymnasteria valvulata from the 
Galapagos Islands is a very young form, on the specific validity of 
which it is somewhat hazardous to place reliance. 
B. Bathymetrical range: Shallow water. 
y. Nature of the Sea-bottom: Not recorded.
