The author accompanied Professor Hackel to the Canary 
Isles in the winter of 1866-7. Though the fauna of the coast of 
the islands was not as rich as was expected, yet on clear, calm 
days the charming Eurhamphcea vexilligera swam by in swarms 
on the surface of the ocean, accompanied now and then by a 
species of Beroe ; a single example of Eucharis multicornis and 
but two of Cestum veneris were seen. A new genus belonging 
to Cestidoi was also met with. The author promises to describe 
more particularly the nervous system in a work to be soon pub- 
lished on the minute anatomy of Ber'o'e.

species, there is also appended a selected list of works written
