examples — those contained in the Stephensian Collection- 

 But it will be said, it does not agree with the Linnsean 

 description, which states that the legs are black, and the 

 description must be correct ; I am not so sure of that. That 

 descriptions can and do err may be shown from a case in 

 point : M. Jacquelin-Duval argues that Dr. Schaum, as well 

 as myself, must be in error in assigning B. pusittum as the 

 type of Lopha pulicaria of the Stephensian Cabinet, because 

 Stephens expressly states that the latter has oblique frontal 

 foveas ; yet it is a matter that admits of not the slightest 

 question that the type is B. pusillum, and has parallel 

 frontal foveas, though the Stephensian description says that 

 they are oblique. Suppose Stephens's Collection, instead of 

 coming to us direct from the hands of its compiler and 

 owner, three years ago, had become antiquated like the 

 Linnsean ; or, suppose the question of the types to be dis- 

 cussed some sixty or seventy years hence, with no more 

 definite knowledge on the subject to assist the inquirer than 

 the Stephensian types and the Stephensian descriptions 

 would supply, might it not be argued with equal show of 

 reason, that the types in the present instance must be ignored, 

 as they never could have been intended to represent the true 

 Lopha pulicaria , Steph., because they are antagonistic to 

 the descriptions ? With all their acknowledged authenticity,. 

 M. Jacquelin Duval discredits the fact. In the Stettin 

 Catalogue for 1852 Dr. Schaum adopted the name rupestre, 

 but our author remarks that he has since abandoned it. 



M. Jacquelin-Duval affirms that B. punctatulum, Drap. 

 (Tachypus striatus, Steph.), cannot be the Carabus velox, 

 Linn., of the Fauna Suecica, because that species is not 

 found at all in Sweden, but is confined exclusively to Central 

 and Southern Europe. It is to be presumed that our author 

 is intimately acquainted with every square inch of collecting
