identical with Doridopsis. In 1871 Mr. Pease still adhered to his 
own genus; and he did not consider it synonymous with Alder and 
Hancock’s, for which he at the same time proposed the name 
Haustellodoris. 
While agreeing with M. Bergh that Mr. Pease’s forms are pro- 
bably species of Alder and Hancock’s genus, we cannot follow him 
in adopting “‘ Doriopsis’’ as the generic name, not only because none 
but Mr. Pease’s own species, about which we cannot always feel sure, 
will fall under that genus as defined by him, but also because the 
root of “ Doris” is “ Dorid-,”’ and not ‘ Dori-;’”’ so that ‘‘ Doridop- 
sis” is more correct etymologically than ‘‘ Doriopsis.”’
