PIlErACB. 
The fifth volume of the ^ Record * forms a systematic guide- 
book to about 34,000 pages* of the zoological literature pub- 
lished (with the exception of a small part) within the year 1868. 
The Editor regrets that the publication of the second, and 
consequently also of the third, part of this volume has been de- 
layed to the end of the year; and he will not plead any other 
excuse beyond the fact that, with regard to the regularity of the 
appearance of the volumes, he is entirely dependent on the Con- 
tributors. The first part was published as early as July. 
It was mentioned last year that zoologists are indebted to the 
British Association for a second grant of i01OO towards the 
expenses of the preparation of this volume, the Contributors 
having again made a sacrifice similar to that of the previous 
year.
