according to modern nomenclature. As Vroeg's Sale-list 

 was not published until after the issue of the twelfth edition 

 of Linnseus's ' Systema/ it follows that those who begin their 

 nomenclature with that edition need not trouble themselves 

 about the matter. But even those who, like Mr. Richmond, 

 commence binomial terminology from 1758 should hesitate, 

 we think, to follow his lead, in accepting the validity of the 

 names of Vroeg's Sale-list. There is no proof whatever that 

 the " Adumbratiunculse " were published at all ; thev are 

 paged separately from the " Sale-list. " All we know is that 

 a printed copy of them is attached to Linnseus's copy of the 

 Sale-list, and that it was probably seat to Linnaeus by Pallas. 

 But it is impossible to say whether the " Adumbratiunculse " 

 were issued along with other copies of the Sale-list, or were 

 intended by the author for Linmeus's private use oidy. 

 Therefore it would be unwise to supersede such well-known 

 names as Muscicapa grisola by Muscicapa striata, and 

 Melizophilus undatus by Melizophilus cantillans, &c, as 

 suggested by Mr. Richmond.
