THE MYRIAPODA OP NORTH AMERICA. 145 



Say iu naming- this species was apparently unacquainted with Dr. 

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

 " another. 



In 1841 Brandt attempted to remedy this confusion of names and 

 accordingly called Say's species Julus 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 Nemasoma sayanum 

 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 Julus lactarius, which mis- 

 take has confused the synonymy of Cambala annulata and Callipus 

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

 (Say).

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

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

 identical with the Callipus of Bisso, the name of our American species 

 must stand as Callipus lactarius (Say).

 Spirobolus spinigerus Wood. Proc. Acad. Nat. Sci. Phila., 15, 1864. 



A comparison of specimens which have here before been referred to 

 marginatus and spinigerus with Say's description of this species has con- 

 vinced me that the marginatus of Say and the spinigerus of Wood are 

 identical. Say says his specimens are " glabrous," and this is only true 

 iu specimens of spinigerus, while in our so-called marginatus the seg- 

 ments are very densely punctate. 



Tins conclusion is further strengthened by the fact that the species 

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