deposits, a number of isolated places were observed where a deposit 

 of greensand is still going on. 



Pourtales' researcbes include depths of 700 fathoms, with rich 

 faunas, others often with very poor ones, which seems to show that 

 the fauna is certainly more influenced by the condition of the bottom 

 than by the depth, as the abundance of animal forms suddenly 

 disappears, where stony bottom changes into Polythalamia deposits. 

 The animals live there at a temperature of only a few degrees above 

 zero, and with a small amount of light. The oysters, Annelida and 

 Mollusca, possess developed eyes, rather larger than their relations 

 of the littoral region. 



One of the most important results of the researches of the ex- 

 peditions of 1867 and 1868, is the fact that the Corals and Echino- 

 derma of the deep-sea region possess the entire facies of the Tertiary 

 and Cretaceous faunas.^ — C.L.G.

Bath Natural Histoey and Antiquarian Field-Club. — At a 

 meeting of this Club held on the 15th February, 1871, the Eev. H. 

 H. Winwood, M.A., F.G.S., read a paper on the Rh^tic section at 

 Newbridge Hill, on the new (Midland) Railway between Bath and 

 Mangotsfield.^ This section has been noticed by Mr. C. Moore in 

 his paper, " On the Abnormal Conditions of the Secondary Deposits 

 of the Somersetshire and South Wales Coal Basin," but since his 

 observations were made the banks have been worked back, and 

 greater facilities afforded for the examination of these beds. The Eev. 

 Mr. Winwood has made a careful section of the beds exposed in this 

 cutting, which include a thin representative of the bone-bed, the 

 black shales, the Cotham Marble and the White Lias of Rhaetic age, 

 while resting upon these come the Ostrea and Angulatus beds of the 

 Lower Lias, which are mostly wanting in this neighbourhood, the 

 Lima and BucMandi series, as Mr. Winwood remarks, generally 

 resting unconformably upon the White Lias. Numerous species of 

 fossils are mentioned as occurring in the beds.

In this paper the author desired to record certain examples of 

 objects which had been regarded, erroneously, as vegetable fossils. 

 The specimens to which he specially alluded were as follows : —

 namely, Carpolites umbonatus, Sternb., and Guilielmites permianus,
