I have now come to the end of my remarks which turn on questions of 
chronology or priority; and I proceed to enter a protest against a mode of cita- 
tion which Mr. Smith has in some cases adopted. When papers are published in 
the Transactions of a Society, or a periodical, the reference should be given to the 
volume of the Transactions, or to the periodical by its title, not simply to the title 
of the paper. In the case of some papers of Nylander’s, published by the Academy 
of Sciences of Helsingfors, a paper of Schenck’s, published by the Natural History 
Society of Nassau, the above-mentioned paper of Smith’s published by the Ento- 
mological Society of London (only once cited in the Catalogue), and a paper (of 
only 8 pages, twice cited) of Wesmael’s published by the Academy of Sciences of 
Brussels, Mr. Smith has referred to the title of the papers themselves, thus 
‘Nyland. Mou. Form.,” “ Nyland. Ap. Bor.,” and not to the works in which they 
appeared. These papers were never separately published as independent works, 
and I see no reason why they should have been cited in a different way from the 
numerous other papers—published (say) in the Trans. Lin. Soc. Lond., the Ann. 
Soc. Ent. Fr., or the Stett. Ent. Zeit.—to which Mr. Smith makes reference. 
Schenck’s Nass. Bien. was originally published in the Jahrb. Ver. Nass. in 1859, 
and was also published as a separate work in 1861; but even in this case it would 
have been better to cite the earlier print rather than the later reprint. I may add 
that two supplements to “ Nass. Bien.” have appeared in the Jahrbiicher for 1863 
and 1869, but to neither of these, nor to the papers on Bees by the same author in 
Stett. Zeit. 1870, does Mr. Smith refer, though the conclusions arrived at by 
Schenck are in some respects at variance with those of the Cataloguer. 
No author is cited by Mr. Smith so frequently as Nylander: to “ Ap. Bor.” 
“Ap. Bor. Supp.” and “Ap. Bor. Revis.” alone there are more than 120 references ; 
and when we turn to the list of Abbreviations (p. vi.) to learn where and when 
these works appeared, we are informed that they, as well as the “ Mon. Form.” and 
“Mon. Form. Addit.,” are published in the Acta Soc. Sci. Fennicz. It is true the 
“Mon. Form.” and its supplements (for there are two) are published in the Acta; 
the “ Ap. Bor.” and its two supplements however are not in the Acta at all, but in 
a “ Bibang till Acta” entitled ‘“ Notiser ur Sillskapets pro Fauna et Flora Fennica 
Foérhandlingar.’ As these Helsingfors publications are little known in this 
country, it may be serviceable to add the following particulars concerning them. 
The publication of the Acta commenced in 1840; and the two first volumes 
(1840-47) contain half-a-dozen Entomological papers by Sahiberg and Mannerheim ; 
in the 3rd fasciculus (1846) of the 2nd volume will be found Nylander’s Adnotationes 
in Monographiam Formicarum borealium Hurops (which was read before the 
Society on the 9th February, 1846), and also the Additamentum Adnotationum &c. 
(which was read on the 9th November, 1846). In the 3rd vol. of the Acta (1852, 
on the title page) will be found an Additamentum alterum Adnotationum &c. 
(said to have been read on the 1st November, 1846, but this must be a misprint, 
probably for 1849). About 1847 it seems to have been thought that it was desir- 
able to separate the zoological and botanical papers from the rest, and accordingly 
the ‘‘ Notiser’’ were started for their reception. As however Nylander’s Mon. 
Form. and the Addit. had appeared in the Acta, on this account (I presume) the 
Addit. alterum was inserted in the Acta; but, with this exception, there is no 
zoology in the Acta of later date than 1846. The Notiser were at first published
