sedulous in restoring the neglected or misapplied trivial names of the Linnean 
age, and of that immediately succeeding,. to their rights, from which they 
had been carelessly .deposed in favour of later intruders. Something yet 
remains to be done in that direction; and even now we could specify a 
dozen names of the last century, still awaiting the recognition of their 
legitimate priority, within the scope of the present list. 
A perfect agreement of opinion as to what are genuine species, and what 
mere varieties, must be a work of time, if it be even so ultimately attainable. 
Thus, circumspect as Mr. Dawson has shown himself, sometimes almost 
severe, as to the admission of species, we were rather surprised to see 
Cicindela maritima Dej. figuring as a species, almost at the head of the 
list. The evidence Schioedte has adduced seems quite conclusive against 
the distinction of this even previously questioned species ; and the authors 
of the contemporary Faune Fram^aise unhesitatingly take the same view. 
On the other hand, Mr. Clark, in reducing the multiplied species of Hetero- 
cerus to three only, in the British islands, has excluded one, H. femoralis 
Ksw. (wherewith we identify also H. arenarius of the same), which we are 
unable to refer to any of these three, and which is not noticed among the 
synonyms he has given. The array of synonyms seems to have been 
designedly limited to those most likely to be of use to British students • 
but we have sometimes found ourselves at a loss to determine on what 
principle the selection has been made. Here and there, a variation from 
conclusions adopted in the Geodephaga Britannica shows that the list is 
not a mere extract, or index, but has received an independent revision at 
the hands of the authors. We hope soon to be in possession of a corres¬ 
ponding list, which is still more urgently called for, of the Brachelytra, as 
the result of the investigations now in progress by Messrs. Waterhouse and 
Janson. Meantime, we can safely recommend Messrs. Dawson and Clark’s 
list, as an example of what is wanted, and as incomparably the best extant 
for the use of British collectors, as regards the families which it comprehends.
