S. I. Smith describes the metamorphosis of the crus- 

 tacea (3, 401, 1872; 6, 67, 1873), species of Crustacea (3, 

 373, 1872 ; 7, 601, 1874 ; 9, 476, 1875), and dredging opera- 

 tions in Lake Superior (2, 373, 448, 1871). In this series 

 occurs also a series of papers on comparative anatomy 

 and embryology from the Chesapeake Zoological Labora- 

 tory in charge of W. K. Brooks. In the 39th and 40th 

 volumes of the third series (1890) occur several papers 

 on evolutionary topics by John T. Gulick (39, 21; 40, 1, 

 437) which have attracted much attention. 



Before the end of this period, however, the Journal 

 was relieved from the necessity of publishing zoologi- 

 cal articles by the establishment of several periodicals 

 devoted especially to the various fields of zoology. We 

 find, therefore, but few exclusively zoological papers 

 after 1885, although articles of a general biological inter- 

 est and the reviews of zoological books continue. 

 * In the fourth series of the Journal, beginning in 1896, 

 occur also a number of articles on systematic zoology by 

 Verrill and others and several papers having a general 

 biological interest. Brief reviews of a small number of 

 zoological books are still continued, but at the present day 

 the Journal, which played so important a part in^the 

 early development of American zoology, has been given 

 over to the geological and physical sciences in harmony 

 with the modern demand for specialization.
