 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 by his elaborate work on Corallines; he addresses it 

 in a letter to Mr. Isaac Romilly.
