lapidibus calcareis frequentissimus, nee non cirea fturaen 

 Jenissej ad pagos Nisehuij Inbatskoj (63° 50') et Vorogova 

 (60° 55'). 



The specimens from Waigatsch coiTespond better than those 

 from Yenisei with 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 

 Litliohius 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 remark 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. forficatns (Linn^) from North-east America and the 

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

 Sweden, there is no species of the genus Lithohiufi^ 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 Finmark and the north of Finland, and now in 

 the island of Waigatsch and far into Siberia near the river 

 Yenisei.
