It seems to me necessary to restore the name of Dufour for this species, 
as his description was published four years before any by Nitzsch, and 
in the first indication of the Nitzsch description (Burmeister, Handbuch 
II, p. 433) Dufour’s name is given, and it is simply stated in parenthesis 
that it is the taurus of Nitzsch’s MSS. On what ground Giebel should 
have resurrected the name taurus, or why Piaget should follow him in 
it, I fail to see, as both were familiar with Dufour’s description. 
Piaget considers the L. pederiformis of Dufour an example of taurus 
not fully developed (in way of development).
