contented myself with describing the more conspicnpns varieties of these young 

 Octopods, but without affixing any specific names. 



The information given by these young specimens is, however, satisfactory, inasmuch 

 as it shows that even at so early a period different forms can be separated from 

 each other by characters as definite as those which are used in the discrimination of 

 the adult species, not that this is saying much in the case of Octopods, for we are 

 still very much in the dark as to the best specific characters and the range of 

 variation in this bewildering genus.
