The specimens from Waigatsch correspond better than those 

 from Yenisei witli the Scandinavian ones. Those from Yenisei, 

 namely, differ in appearance by being much darker brown in 

 colour ; and their dorsal shields are very densely covered with 

 hairs, which is seldom the case, and then only in a slight degree, 

 with the specimens from Waigatsch, and, as far as I know, 

 never with Scandinavian or South-European specimens. 



Meinert [op. cit. 1872, pp. 341, 342) has noticed that the 

 Lithohius curtipes^ adopted by Palmberg in 1866, by v. Porath 

 in 1869, and by me in 1871 as one of the Myriopods of Sweden, 

 is not C. L. Koch's species of the same name, but a form of 

 L. crassipes^ L. Koch. He also corrects an error in C. L. 

 Koch's, L. Koch's, and my own statements regarding the 

 situation of the process-like appendage which characterizes ' 

 the fifteenth pair of feet in the male. I avail myself of this 

 opportunity to admit the truth of all this. I also remaric that 

 the L. curtipes^ C. Koch, does not occur, or, at least, has not 

 hitherto been found within the Scandinavian provinces, and 

 as little in Sweden and Norway as in Denmark. Excepting 

 the L. forficatus (Linne) irom North-east America and the 

 entire west of Europe from Italy and Spain to tlie north of 

 Sweden, there is no species of the genus Lithohius^ so rich in 

 forms, that for wide geographical distribution can at present 

 compare with L. crassipes, which has already been found,, at 

 Bona on the coast of North Africa, in Spain, in the south of 

 Tyrol, in Bavaria, in Denmark, in the south and middle of 

 Sweden, in Einmark and the north of Finland, and now in 

 the island of Waigatsch and far into Siberia near the river 

 Yenisei.
