lefifs. At the saino time the Cmboniferous Anthracarldiv were ])robably 

 the forerunners or ancestors of the Mesozoic and hiter Eryonidw. From 

 the nature of the diflerentiation of the tel.son iu the Galatheidcc the 

 author is inclined to believe, from what he has observed from the speci- 

 mens before him, that the telson of Antlirapalcvmon is subdivided in 

 nearly' the same manner. If so, the genus cannot be referred to the 

 Uryonidcc, and should therefore be regarded as the tyi)e of a distinct 

 family, which he calls Anthracaridcc, and briefly characterizes.

 A general review of PaljEOzoic scorpions ; cites the genus Eoscorpius 

 Meek and Worthen. States that Professor Lindstrom shows that Pa- 

 IccopJwneus nuncius was a land animal and a true air-breather. Con- 

 siders that Gyrichnites, of the Lower Devonian of Gaspe, may have been 

 animals which supplied food to the ancient scorpions.

says that they are the first specimens seen by him from America. Prof.

Mr. Pohlman states that the scorpion described by Professor Whit- 

 field on pages 87 and 88 of Science, vol. vi, is undoubtedly a young spec- 

 imen of Eusarcus scorpionis (Grote and Pitt; Bulletin of the Buffalo 

 Society of Natural Sciences, vol. iii, i)p. 1, 2), so named by an error, 

 and which will be redescribed as Eurypterus scorpionis in the forthcom- 

 ing vol. V of the society's bulletin. He gives a figure of the youngest 

 specimen in his possession. 



In a note Professor Whitfield gives his reasons for not believing the 

 fossil described by him to be the young of that or any other Eurypteroid.
