THE MYRIAPODA. OF NORTH AMEKICA. 145 



Say iii naming- this species \v as apparently unacquainted with Dr. 

 Leach's species and used a name which had already been given to 

 another. 



In 184-1 Brandt attempted to remedy this confusion of names and 

 accordingly called Say's species Jain* stigmatosus, but even this name, 

 as shown above, is preoccupied. 



In accordance with the rules of nomenclature, this name must be 

 changed, and as a tribute to Dr. Say, its original describer and our 

 first American myriopodist, I would call this species Xnntimntin .saynuni 

 Bollman, nom. nov.

Say's description of this well-known species seems to apply to the 

 southern form, a fact which is strengthened, by the locality, "Southern 

 States ", which he has assigned to his specimens. This is the species 

 sent to Dr. Leach by Say under the name of Jxlua lt'trinn, which mis- 

 take has confused the synonymy of Cambala annulntn and C alii pus 

 lactarium. The name of this species now stands as Cambala annnlata 

 (Say).

This widely distributed and well-known species was made by Brandt 

 the type of his genus Lysiopetqlum, but as Brandt's genus seems to be 

 identical with the C'dUipiin of liisso, the name of our American species 

 must stand as CaH'ipns l<-tarii<x (Say).

A com])arison of specimens which have here before been referred to 

 maryhiatns and spiniucrus with Say's description of this species has con- 

 vinced me that the iar<iina1ns of Say and the spinitH'nis of Wood are 

 identical. Say says his specimens are " </labr<mN," and this ismily true 

 in s]ecimens of .^/tinii/criin, while in our so-called marginatus the seg- 

 ments are very densely punctate. 



This e.mclusion is further strengthened by the fact that the species 

 we have referred to maryinatuK is not found in Florida or southern
