Zool. Record, 1865, p. 713). The author having consulted the 
type specimens of many of Dr. Johnston^s species in the British 
Museum, has been able to correct to a very large extent the 
synonymy of the ^Catalogue of Worms in the British Museum.’ 
The author states that this memoir contains the principal 
results of his examination of the rich collection of Annulata 
from the North Seas, to be found in the Royal Swedish Natural- 
History Museum at Stockholm. The geographical and bathy- 
metrical distribution, when not otherwise mentioned, is always 
quoted from the specimens in the museum, or from the author’s 
own experience. One or two species are referred to that do. 
not belong to the regions of which this memoir more particu- 
larly treats, but these are left without a consecutive number. 
The plates were all drawn and engraved under the author’s 
superintendence, and with the greatest possible accuracy. The 
greater number of the figures, as well as the most important 
microscopic details, were delineated by means of the camera. 
An index to the genera and species, however, is wanting.

The author calls attention to the partially forgotten and much 
overlooked work of Delle Chiaje, and briefly criticises the recently 
published works of Quatrefages and Ehlers. 
This very interesting critique, which forms part of the intro- 
duction to a work on the Annelida of the Bay of Naples, already 
in the press, will be consulted by all taking any interest in the 
study of the Annelida : here we can do nothing more than call 
our readers’ attention to it. ^ 
M. ClaparMe, while he refuses to Ehlers’s work the merit of 
being a treatise on Annelida,” praises it as a model of exacti- 
tude. He follows step by step Quatrefage’s ^ History of Anne- 
lids,’ annotating and correcting the statements made therein. 
Even though Prof. ClaparMe’s criticisms are sometimes severe, 
yet it is impossible not to admire the straightforward candour 
that pervades the whole of this paper, the justness of most of 
his remarks, and the great ability which characterizes them.
