ZOOLOGICAL LITERATURE. 
2j and 6 belong to tome vi., and nos. 3 and 5 to tome v. The 
only safe guide appears to be the press-mark at the bottom of 
each separate sheet, the wrapper being evidently untrustworthy. 
To add to the difficulty, a new series of the work has been com- 
menced, of whicli vol. vii. of the old series forms vol. i. The 
first and second livraisons of this volume, respectively dated out- 
side January and February 1870, are dated inside 1869, as the 
volume is supposed to be for 1869-1870. Under this new 
arrangement a livraison is to be published every month, the 
quantity of pages being, of course, diminished from the old 
standard.
