by, Haeckel! Uljanin, F. E. Schultze, and others, between the 
genera Caramina and Cunina. Fritz Müller has described a like 
commensalism in Glossoco- 
don (Liriope) and Cunina from 
South American waters. 
Later investigations may 
show that our species are the 
same as his, and probably 
stragglers from warmer south- 
ern waters. To those espe- 
cially whose good fortune it 
is to cultivate the study of 
the Medusæ of these locali- 
tes, we must look for new 
observations. On the New 
England coast both genera 
are very rare. The genus
