from various Bs and of both sexes, the average length 
from tip of tail to dorsal edge of the mantle was 696 
inches; from tip of tail to insertion of fin, 2°59 ; average pro- 
portion of fin to mantle-length, 1: 2°68. Among these the 
aig varied from as low as 1: 2:50, in some of the 
arger ones, (with mantle above 8 inches), up to 1: 2°85, in the 
smaller ones, (with the mantle about 4 inches long). The cau- 
dal fin is about one-third broader than long, and its breadth is 
usually rather less than half the length “of the mantle. 
fresh specimens the tentacles can extend back beyond the base 
of the caudal fin. The portion of the tentacles bearing suck-
