tion is independent of sex, and is due mostly to the ordinary 
changes by growth. The ratio of the breadth of the caudal 
mode of preservation. The suckers in the two central rows of 
the tentacular club, are large and remarkably high; the mm 1s 
closely and sharply denticulated, one or three minute denticles 
alternating with the larger ones. 
Var. borealis Verrill. Four specimens, taken in 1878, a 
i ass. on the north side of Cape Ann, and sent 
to me by Professor A. Hyatt, differ so decidedly from the 
typical ones that it seems desirable to give the form a distinctive 
name, as a variety or geographical race. Two are females, fil 
with eggs. When a larger series can be examined it may even 
prove to be a distinct species. They have the general form and 
appearance of the pale-colored ZL. Peualei, with the caudal fin 
broader than usual. Ratio of fin-length to mantle, 1:1°62; of fin- 
‘width to mantle-length, 1:1-82. Length of mantle, above, 10 one 
female, 7°30 inches; of caudal fin, 4:5; to end of longest sessile
