Several of the smaller specimens, included in this list, are so young 
that it is impossible to determine their sex with certainty, without 
dissection. The hectocotylization of the ventral arm in the male is 
scarcely recognizable in those with the mantle less than 4 inches long. 
The Mediterranean form, usually identified with the car. b, of Loli- 
go sagittata Lamarck, 1799,* is closely related to our species, but if 
the published figures and descriptions can be relied upon, it can 
hardly be identical, as D’Orbigny and other writers have considered 
it. The American form has a more elongated body, with a differently 
shaped caudal fin, which is relatively shorter than the best authors 
attribute to O. sagittatus. The figure given by Verany is, however, an 
exception in this respect, for in it the body is represented about as 
* It seems more probable, however, that Lamarck’s description applied rather to 0. 
Bartramii (Les. sp.) of the Gulf Stream region. Blainville and others have thus ap- 
plied it, correctly, as I believe.
