This species has been taken in numerous localities, by the dredging 

 parties of the U. S. Fish Commission, in 1877, 1878, and 1879, off Cape 

 Cod; in Mass. Bay, 40-50 fathoms; off Cape Ann, in the Gulf of Maine, 

 50-100 fathoms; off Cape Sable, N. S., 88-92 fathoms; off Halifax, N. 

 S., 57-100 fathoms, on a fine, compact, sand and mud bottom. It occurs 

 in 40-100 fathoms. It has also been received through the Gloucester 

 halibut fishermen, from the Banks, off Nova Scotia and Newfoundland. 



One specimen (lot 241), presented by Capt. Chris. Olsen and crew, of 

 the schooner " William Thompson," was taken in GO fathoms, N". lat. 44° 

 20', W. long. 59°. Another (lot 372), which was presented by Capt. C. 

 D. Murphy and crew, of the schooner "Alice M. Williams," was taken 

 in 7 fathoms, off Miquelon Island. 



The relatively large eggs (PI. XXXV, fig. 5) are laid in August aud 

 September, in small clusters, slightly attached together, in the large 

 oscules or cavities of several species of sponges. 



It is frequently associated with Octopus Bairdii V, and the following 

 species. 



This species has a strong general resemblance to B. glaucopis Loven, 

 as figured in the admirable work of G. O. Sars, but the latter has shorter 

 lateral arms, and the suckers of the sessile arms are in two rows, while 

 they are four-rowed in our species.
