was a composite species, part of the wordiog which Linne intended to use in characterizing the black- 

 snake and the hog-nose snake having been combined under constrictor. Thus the scale counts 13(V- 

 40 refer to the hog-nose, the first words " Habitat in Canada. Kalm," refer to the black. Then we 

 read " Maxillae apex simus triqueier," obviously the hog-nose again. Lastly comes an abbreviated 

 extract of Kalm's account of the black snakes' habits " Adoriiur homines circum pedes sese convolvens, 

 sed innocuus.** Consequently, Coluber constrictor of 1758 being a composite species, Linn6, in 1768, 

 exercised his prerogative as first reviser to correct this error. So that in the twelfth edition (p. 386) 

 we find the black snake correctly diagnosed, using much of the same wording as was used in 1768, 

 with the name constrictor applied; while on p. 873 we find the hog-nose renamed — conU)Ttrix — and 

 assigned to the genus Boa. The description fits the hog-nose snake accurately, again part of the early 

 diagnosis being repeated and reference is also made to Catesby's plate figuring this species. This, 

 renders the name contoririx untenable for the Copperhead.
