VERRILL, A. E. 



1873. Report upon the Invertebrate Animals of Vineyard 

 Sound and the Adjacent Waters, with an Account 

 of the Physical Characters of the Region. U. S. 

 Comm. Fish and Fisheries. Rep. on the Condition 

 of the Sea Fisheries of the South Coast of New Eng- 

 land in 1871 and 1872. Part I. Senate Misc. Doc. 

 No. 61, 42d Cong., 2d Sess., pp. 295-778. 

 An early descriptive associational and habitat study 

 of the marine animals of our coast. A kind of work, 

 in its standpoint, far in advance of the times. It is 

 remarkable that this well-known work has not been 

 a model for other similar studies on our coast.

 writer. Similar work should be done in American 

 waters.
