500 A. E. Verrill—Results of recent Dredging Ecpecitions 
Hydroids were abundant, 
in the shallower waters of Casco Bay and Bay of Fundy. 
Among the Actinians were Urticinu nodosa and Bolocera Tuedie, 
both of which were added to the American fauna last year by 
our dredgings near Saint George’s Bank and in the Bay of 
Fundy, and were also obtained this year off Casco Bay. Cornu- 
lariella modesta V. (plate v1, figs. 1,2) occurred on Jeffrey's 
Ledge. Sponges were very abundant on Cashe’s Ledge, and of 
many species: among them were Thecophora ibla ‘Thompson 
(plate vim, fig. 8), also dredged last year by the Saint Georges 
Bank expedition; Tethya hispida Bowerbank; two or three 
often nearly hemispherical, a two to four inches
