Thorell, T. Oil Proscorpius osboruei, Whitfield. (Amer. Nat., vol. 

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



The author can not find that 7Vo.sco/-jji«s diifers essentially from the hitherto 

 known scorpions in other respects than i n the somewhat shorter cephalothorax, 

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

 pears to him to he in the close vicinity of Palaophonus, 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 Eoscorpioidw, and for referring this genus to the Apoxypodes, fam. Pnlce- 

 ophonoidfc, may be found in its being, geologically speaking, almost con- 

 temporary with the PaUi'ophoni, belonging, like these, to the Upper Silu- 

 rain formation. As the Palwojjhoni, and all other more recent scorpions, 

 are undoubted land animals and air-breathei\s, and as no traces of branchiae 

 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 

 h.ave hero a link between the true aquatic forms, the Eurypterusand Ptery- 

 gotus, and the true air-breathing scorpions of subsequent periods," as Mr. 

 Whitfield supposes.
