natural size the Caulopteris antiqua Newb., of the Corniferous 

 limestone. The fine specimen was from Sandusky, Ohio. In the 

 same rock occur C. peregrina Newb., Sphenophyllum vetustum 

 Newb., and Lejridodendron Gaspianum Dawson. The C. pere- 

 grina is also figured and described, together with Dadoxylon 

 Newberryi of Dawson, and the Sphenophyllum and Lepido- 

 dendron mentioned. 



12. XT. S. Geological Survey Bulletins. — The Survey has re- 

 cently issued Nos. 48 to 53 of its bulletins, as follows ; No. 

 48. On the Form and Position of the Sea-Level, by R. S. Wood- 

 ward. 88 pp. 8vo. — No. 49, Latitudes and Longitudes of certain

13. Geological Survey of Missouri. — A letter from Mr. Arthur

 geologist of Missouri and has entered on his duties. 



14. Geologic der Munsterthals in JBadischen Schwarzwald, by 

 Dr. Adolph Schmidt, Prof. Univ. Heidelberg. (Carl Winter). — 

 The first part of this work on the geology of the Mtinsterthal 

 appeared in 1886, the second in 1887, and the third, in 1889. The 

 last extends to 112 pages, and treats of the ore-deposits; first 

 of the associated minerals and their paragenetic combinations, 

 and then of their paragenesis. Dr. Schmidt is one of the best 

 authorities on the subject, and his work sheds light on mining 

 deposits generally. 



15. Contribuzio?ii alia Flora Fossile dei Terreni Terziarii 

 delta Liguria • by S. Squitntabol. 1. Fucoidi ed Fhnintoidee, 

 Roma, 1888 ; II. Caracee-Felci, Genova, 1889. — These two con- 

 tributions seem to be the beginning of a somewhat extensive 

 work by the author on the fossil flora of Liguria, but as the first 

 was published in the Bolletino of the Italian Geological Society 

 in octavo form and the second by the University of Genoa in 

 quarto form they cannot be brought together into a volume. 

 Judging from the work already done by Gaudin, Massalongo, 

 Sismonda, Sordelli, and others in the beds of this age in Liguria 

 and the adjoining provinces the greater part of the fossil plants 

 met with are dicotyledonous leaf impressions, and it is gratifying 

 to note that the lower forms are receiving attention. The -fu- 

 coids described in the first paper are problematical organisms 

 referred to Chondrites, Laminarites, Zonarites, Milnsteria, Hel- 

 minthoida, and a new genus Eoclathrus. There are twenty 

 species, twelve of which are new. They appear to represent a 

 formation equivalent to the Flysch of Switzerland. The second 

 paper describes one species of Chara and thirty-two ferns belong- 

 ing to eighteen genera. The figures are for the most part photo-
