lion which the Eutomostraca hold in the class of Crustacea 

 agrees strikingly with their early appearance in geological 

 times ; while the form of the adult Cirripeds 1 and that of 

 the Lernseans would hardly lead one to suspect their near 

 relationship, which has, indeed, been entirely overlooked, 

 until the study of their metamorphoses showed that their 

 true position is among the Crustacea. In the development 

 of the higher Crustacea, 2 their superior rank is plainly ex-
