Report on the Anthozoa, and on some additional Spjcies dredged hy the 

 "Blake'' in 1877-1879, and hy the U. S. Fish Commission Steamer 

 ''Fish Hawk'' in 1880-82. By A. E. Verrill. 



In order to make the following report more complete, all the species of 

 Anthozoa dredged by the U. S. Fish Commission, during the past three 

 seasons, in deep water along the Gulf Stream Slope, off the southern coast 

 of New England and off Chesapeake Bay, have been combined with those 

 dredged by the Blake along the whole coast, from off South Carolina 

 to George's Bank. A large proportion of the species were dredged both 

 by the Blake and by the Fish Hawk, but the collections made by the 

 latter are much the largest, and contain a number of species not taken 

 by the Blake. Other species, poorly represented in the collections of 

 the Blake, were secured in large numbers, and of various ages, by 

 the Fish Hawk. Moreover, the dredgings by the Fish Hawk having 

 been made under the immediate supervision of the author, they have 

 afforded him opportunities to study and make descriptions of many of 

 the species from living specimens. Most of the drawings of the Actini- 

 ans were also made by Mr. J. H. Emerton from living specimens ob- 

 tained by the Fish Hawk, and kept alive in our aquaria. For the use of 

 those drawings, on this occasion, we are indebted to the kindness of 

 Professor S. F Baird, U. S. Commissioner of Fish and Fisheries. 



A few deep-water species, that have been obtained only by the Glou- 

 cester fishermen on the deep fishing grounds off Nova Scotia and New- 

 foundland, and by them presented to the U. S. Fish Commission, have 

 also been introduced, to make the list more complete. From these
