This advantage seems to have been particularly attended to by 
Gualtieri, who may be considered as having given excellent hints 
to ichniographists; for his figures are no where unnecessarily mul- 
tiplied (which is more than can be said in praise of Seba), and 
they have an obvious connexion with the more satisfactory de- 
termination of species. It is much to be lamented that in many 
other works, which (except in this particular) are of high value, 
his judicious example has been wholly overlooked. 
BORLASE, 
the indefatigable historian of Cornwall, is to be applauded for 
giving a pretty copious catalogue of the shells found in that 
county, which, from the position and extent of the shores, are very 
numerous. His 28th plate contains nearly thirty figures of Tes- 
tacea, and they are very correct. The author displays but little 
science in this branch of natural history, and his descriptions are 
copied from some of the oldest writers on the subject. 
There are some good figures, accompanied by descriptions, of 
several species of Lepas, in the Philosophical Transactions. The 
author of this description was 
JOHN ELLIS, 
well known b} T his elaborate work on Corallines; he addresses it 
in a letter to Mr. Isaac Romilly. 
The figures of shells in
