Thorell, T. On Proscorpius osbornei, Whitfield. (Amer. Nat., vol. 

 XX, pp. 269-274, March, 1886. Philadelphia.) 



The author can not find that Proscorjji ms difi"ers essentially from the hitherto 

 known scorpions in other respect.*^ than i n the somewhat shorter cephalothorax, 

 and perhaps in the form of the mandilAes. Its systematical position ap- 

 pears to him to he in the close vicinity of Pula'ophonus, and especially of 

 the Scotch scorpion referred to that genus by Mr. Peach. An additional 

 reason to those given above for removing Proscorpius from the Carbonifer- 

 ous Eoscorpioidiv, and for referring this genus to the Apoxijpodes, fam. Palw- 

 ophonoida', may be found in its being, geologically speakiug, almost con- 

 temporary with the PaUvophom, belonging, like these, to the Upper Silu- 

 rain formation. As the Pala'ophom, and all other more recent scorpions, 

 are undoubted land animals and air-breathers, and as no traces of branchise 

 have been shown to exist in Proscorpius, there is, he believes, no serious 

 reason for considering that this scorpion is an aquatic animal, or that "we 

 have here a link between the true aquatic forms, the Eurypterus and Ptery- 

 f/otus, and the true air-breathing scorpions of subsequent periods," as Mr. 

 Whitfield supposes.
