REPORT OF THE COMMITTEE 
§ XLIII. Naturalists will do well to bear in mind the following sug- 
gestions : 
A. Indicate exactly the date of publication of each work or portion of a work, or 
of the distribution of named specimens of plants under § XXXVI. (DC.) 
It would be very useful if scientitic journals or works on bibliography would denote 
the exact date of reception or actual publication of volumes or plates appearing suc- 
cessively, or in which one is liable to be deceived by the title pages, or where doubt 
arises from the absence of dated title pages. This is especially the case with works 
appearing in parts. In regard to plants in well conducted herbaria, the date of recep- 
tion (which is almost always that of distribution) is usually noted on the labels. (DC.) 
B. Do not publish a name without clearly indicating the nature of the group (tribe, 
genus, section, species or variety) to which it is supposed to belong. (DC.) 
C. Avoid mentioning or including in any publication unaccepted manuscript names, 
above all when the persons who gave these names have not formally authorized their 
publication. (DC.) 
To publish a name which cannot be adopted, or which is undefined by the person 
citing it, or some previous author, is wantonly to throw a synonym into circulation, at 
least in tables and bibliographies. 
Our nomenclators would be of double size if they contained all the names which 
exist in travellers’ note books, museum and herbaria, and which have not the slightest 
value. Names of this kind when printed are still-born. Why then augment their 
number unless at least the author asks that they be made public. 
Of the Precision to be given to Names by the Citation of 
the Author who First Published them. 
XLIV. To be exact and complete in the indication of the name or 
names of any group, whatever, it is necessary to cite the author who has 
first published the name or combination of names in question. 
A. When it is desired to indicate that the author proposed the whole 
name in the form in which it is cited, his name or an abbreviation of it 
simply follows the specific name; as Anomia craniolaris, Linnaeus, or Lin. 
or L. 
B. When it is desired to indicate that the application to the species of 
the specific name is all that is due to the author cited, the abbreviation of 
his name may be either (1) enclosed in parenthesis [e. g., Crania cranio- 
laris (L.)] ; or (2) followed by the abbreviation sp., as Crania craniolaris 
L. sp. 
C. When it is desired to indicate the author of the combination cited, 
together with that of the person who first proposed the specific name, the 
name of the latter or its abbreviation is usually written in parenthesis 
followed by the name of the author of the combination cited (e. g., Crania 
craniolaris (L.) Nilss.) ; or the name of the author of the combination 
follows the specific name separated from that of the author of the specific 
name by the word ex (example, Crania craniolaris Nilsson ex L-). The 
latter mode does away with parentheses and seems preferable. 
D. When it is desired to indicate still more fully the relation of the 
author of the specific name to a former generic combination, the name of 
the author of the cited combination is followed by a parenthetical clause 
consisting of the name of the author of the specific appellation separated
