states it to be the male of Podocerus. The general 
resemblance of this genus to Podocerus is very con- 
siderable, as may be seen by our figure of D. punctatus , 
which was first described as belonging to the genus 
Podocerus. We have, therefore, little doubt but that 
Kroyer, while he distinguished the true relationship 
existing between Cerapus and Dercothoe , was misled, 
from the resemblance of the latter to Podocerus , to con- 
sider that genus as being the female of Cerapus. 
Stimpson, in his descriptions of Cerapi in his c< Marine 
Invertebrata of Grand Manan,” appears to have been 
aware, both of the distinction and relationship between 
the male and female of the genus Cerapus , without 
having fully appreciated its important bearing in relation 
to the observations of Dana and Kroyer.
