20 Prof. KóruikER on the Structure of 
So far De Blainville. According to my views it follows from these observa- 
tions of Madame Power, which Maravigna, as he told me himself, has repeated, 
(presupposing that they are entitled to full confidence,) that undoubtedly a 
vermiform animal quite similar to the Hect. 2 rgonaute, which possesses two 
rows of suckers, is thicker at one end, and furnished at the other with a fili- 
form appendage, is contained in the eggs of the Argonaut. It would thus be 
proved that the Zectocotyle which has male organs only, is the male of the 
Argonaut. But however much I may wish to give full credit to the observa- 
tions of Madame Power and Maravigna, I will not conceal some objections 
which occur to me on the subject. Madame Power and Maravigna state that 
they have seen the young vermiform Argonaut escape from the egg. It is 
easy to perceive that everything depends on the interpretation to be put on 
this expression. If it is not to be taken literally ; if they merely mean to say 
that in the egg-bag of an Argonaut they have found little worms which 
resemble the arm of an Argonaut, nothing whatever is proved by it. But if 
we are to take the observation exactly as it is related and not otherwise, it is 
of the greatest importance. In this latter case the only remaining question 
would be, whether Madame Power and Ma 
ravigna in fact found an entire 
egg-bag attached to the shell of Argonauta full of Hectocotyle-like embryos, 
or whether they saw among egg 
j : S with the common embryos a few with ver- 
miform. animals. In the latter case the eggs might have been the eggs of 
Hectocotyle; in the former no doubt could remain that the Hectocotyle are 
the males of the Argonaut.

of my own on this point, I can 
give no decided opinion. All that I EP
