After + examining the Bradelle Satis, we made for Pe 
N.N.E. of Cape George (N. S. S) and from there to a little dis- 
tance off Port Hood, C. B. We next stood over to the east 
point of Prince Edward Island, mate ta at intervals on the

From Pictou to Bort Hood and along the west side of Cape 
Breton, the sea bottom consists of red clayey mud, in which 
annelids are remarkably numerous and often of large size. At 
almost every cast of the dredge, tangled masses of tubicolous 
annelids (inhabiting tubes of from the jth to a quarter of an

Off the east point of Prince Edward Island the bottom is 
sandy, and as the depth where we dredged does not exceed
