• In 1895 Dr Clemens Hartlaub published a paper on some comatuUds from 

 the Bay of Panama, the first definitely known from the eastern Pacific, announcmg 

 the important discovery of Florometra (Carpenter's "Esclirichti group oi Ante- 

 don) ^vithin the tropics, and extending the known range of one^species of that 

 eenus {Florometra magellanica) from the Straits of Magellan to Panama; at the 

 same fime he described a new species of Florometra from Panama, and three spe- 

 cies of other genera from the Galapagos Islands; in an appendix he described a 

 new Lamfrometra from Gaspard Strait, between Banka and Bdleton. The species 

 mentioned by him are:
