Professor G. O. Sars has taken it oft* the Norwegian coast, in 60 to 

 300 fathoms. 



It occurs both on soft muddy bottoms and on hard bottoms. Both 

 sexes often occiir together, but the males are usually the most 

 numerous. 



Recently hatched young have been taken in August and Septem- 

 ber, in the Bay of Fundy, oft" Halifax, N. S., and oiF Cape Ann, 

 Mass. (at stations 45, 85, 234, 238, etc.). 



One of the specimens obtained by Mr. Agassiz is remarkable for the 

 length and slenderness of the cirrus above the eyes (Plate LI, fig. 

 1, la). This is an immature male, and does not appear to difier in 

 any other way from ordinary specimens, of similar size. The append- 

 age of the hectocotylized arm is small and not fully developed (as is 

 always the case in yoi;ng males), and has an ovate-triangular form, 

 a slightly concave surface, and only a few transverse lamella?.
