376 Coe — A Century of Zoology in America. 



dates. The explorations of the U. S. Fish Commission 

 Steamer "Albatross" are described from year to year by 

 Verrill, with descriptions of the new species of inverte- 

 brates discovered. 



The nnmerons original contributions by Verrill on 

 subjects of general zoological interest as well as on those 

 of a systematic nature give this third series of the Jour- 

 nal much zoological importance. Verrill 's papers cover 

 almost the whole field of descriptive zoology, but are 

 mainly devoted to marine invertebrates. Those which 

 were originally contributed to the Journal or summarized 

 by him in his literature reviews include the following
