Crustacea ; he, again, it was who showed that Pentacrinus is 

 the larval form of the feather-star, Antedon. 



The custom of naturalists to go on long voyages was 

 still maintained, and during the nineteenth century, many 

 other expeditions besides that of the Challenger, left Great 

 Britain to explore the natural history of the world, some 

 under public, some under private, auspices. They are too 

 numerous to mention. But a word must be said about the 

 wonderful exploration of Central America which has just 

 been completed, under the auspices of F. D. Godman and 

 0. Salvin. The results are incorporated in a series of magni- 

 ficently illustrated quarto volumes which have been issued 

 during the last thirty -six years. Fifty -two of these relate 

 to zoology, five to botany, and six to archaeology. Nearly 

 40,000 species of animals have been described in these 

 volumes, about 20,000 being new species, and nearly 12,000 

 species of plants. There are few remote and partially 

 civilized areas of the world whose zoology and botany are 

 on so secure a basis, and this is entirely owing to the muni- 

 ficence and enterprise of the above-mentioned gentlemen. 



With regard to our own shores, one of the features of 

 the latter part of the nineteenth century has been the 

 establishment of marine biological stations, the largest of 

 which is that of the Marine Biological Association at Ply- 

 mouth. The Gatty laboratory at St. Andrews, the labora- 

 tories at Port Erin in the Isle of Man, and at Cullercoats, 

 have also, for many years, being doing admirable work. 

 All these establishments have devoted much technical skill 

 and time to solve fishery and other economic problems 

 connected with our seas.
