94 SIEBOLD ON HECTOCOTYLUS.

 quod duo maxima acetabula continet; id protendi quasi nervo-

In the same book, chap. x. 1, lastly, Aristotle returns once 

 more to the sexual distinctions of the Cephalopoda in these 

 words : — " Differt a fcemina mas capite (abdomen) oblongiore et 

 id quod genitale vocant piscatores habet in brachio candidum/^ 



The task now remains for those observers who have the op- 

 portunity of investigating that portion of the Mediterranean 

 which lies between Greece and Asia, to decide what species of 

 Octopus Aristotle understood by his ^' Polypus,^' and how far 

 his acquaintance with the sexual relations of the male Octopus 

 coincides with the history of the Hectocotylus as it has been 

 recently made known.
