sea ae Sis of “separata”’, dates of publication, and methods of publi- 
cation, is well worthy of special consideration at the next Zoological Congress. 
Among other matters, directly connected with instability in nomen- 
clature, or at least, of trouble in tracing records, is — ae still i 
happily prevalent, of issuing separately paged copies of author’s extracts”’. 
The private worker must as a rule, use these, as he is generally depends 
upon the kindness of the author, or upon purchase of such an extract - 
To the fact that Reuter’s “Revisio synonymica”’, Mulsant and Rey’s “Punaises 
de France“ and other works, were issued thus separately paged, is due the 
almost entire omission of reference to the former in the body of the Cata- 
logue, and the possible incorrectness of some of the references to the latter. 
Sometimes it almost seems as if editors were doing every thing 
possible to make unnecessary work and trouble for their colleagues. For 
instance, I select at random from my Library — 
1. Montandon’s “Hemiptera Cryptocerata* etc. — in the Verh. zool. bot. 
Ges. Wien for 1897 pp. 1—19. On comparing this with the Zoological 
Record, I find the correct pagination is 6—23! 
2. J. Martin’s “Les larves d’Hémiptéres Cryptocerates’’ etc. — in the 
Bull. Mus. Nat. Paris, 1896, no. 6. pp. 1—2. By the same means I find 
the real pagination is 234—35! 
3. Gerstaecker “Bestimmung der von Herrn Dr. F. Stuhlmann in Ost- 
afrika gesammelten Hemiptera’, pp. 1—16, in Jb. Hamb. Wiss. Anst. IX (2). 
In the same way, I find the correct pagination to be 45—58! 
4. Horvath’s “Description of a new species of Gerrididae”’, A. M. N. H. 
(4) II. Feb. 1899, no page mentioned. 
5. Lethierry’s Cat. des Hémiptéres du Nord, pp. 305—74. I am not 
quite sure what the date or journal is, but I believe it is Mém. Soc. Sci. 
Lille 1869. — There is no mention of either in the 70 pages °). 
6. Reiber and Puton’s Cat. des Hémiptéres de l’Alsace, pp. 51—88. 
I have a pencil note that this was published at Colmar in 1877 4), but a 
do not know the reference. 
As it is quite often that various Colleagues, who seem to think that 
I have access to stores of bibliographical knowledge, and who are indeed 
always welcome to any information I can give them, ask for references 
simular to the above, I can only suppose that many others, besides myself, 
are troubled by these faultily published works and separates. {
