THE MYRIAPODA OF NORTH AMERICA. 147 



habitat — " Southern United States' 1 '' — the number of antennal joints — 

 thirty — and the number of scuta with their posterior angles produced — 

 il Jiv€ or six" — 1 have regarded spinipes, trammarinus and mordax as 

 identical. 



Although there is some doubt as to the exact locality of this species, 

 nevertheless I am strongly inclined to believe that Say's specimens 

 were from the Southern States, for out of the nineteen species noticed 

 by Say, only one is mentioned as occurring north of Virginia, south of 

 which State forficatus does not extend. 



This species should still retain Say's name. 



*11. Scolopandra marginata Say. Journ. Acad. Nat. Sci. Phila., 110, 1821. 



This species, the type of which was sent to Dr. Leach, and is now in 

 the British Museum, is identical with the Scolopendra morsitans of 

 Linnaeus.

Scolopendra punctiventris Newport. List. Myr. Brit. Mus., 5, 1844 (Florida).

A valid species.

An examination of a large amount of material has shown that the 

 North American species are the same and identical with the Cryptops 

 hyalina of Siiy.

The type of this species was sent to Dr. Leach and deposited by him 

 in the British Museum. Mr. Newport in 18J-4 made it the type of his 

 genus Thmtops, and on account of the possession of ocelli which he as- 

 signed to this specimen it has been regarded as different from the
