Description of species. 
Descriptive Terms. — In regard to terms of description little need be said. It 
may be as well to note that the term ‘dorsal valve’ means what is called sometimes 
the brachial, sometimes the imperforate, valve; and that ‘ventral valve’ indicates the 
pedicle, or peduncle, or perforate, valve. 
With regard to the phrases ‘this species’, ‘that species’ it may be noted that in 
cases of comparison and elsewhere ‘this species’ refers to the species in hand for 
description at the time, to the Antarctic shells; but ‘that species’ refers to another 
species with which comparison is being made, notwithstanding the fact that it may 
have been the species last mentioned in the sentence. 
To another point attention may be called — that in citations, if the trivial 
name has been given by the author cited, it stands separated from the author’s 
name by a comma; if he is not the giver of the appellation, it stands separated by 
a semicolon.
