54 H. H. Hoicorth — Ahscence of Glaciciiion in 



Sollas's specimens, but turned inwards on the foreign body. This 

 variety occurs in Price's Zones I. Ill, V. VII. and XI. at 20 feet 

 from the top of the Gault, at Copt Point. I have also since found 

 it in the Gault at Battlebridge, Merstham, SuiTey. I have associated 

 the name of Dr. W. J. Soilas with this form, who first described the 

 perforate type. 



Vitriwebbina lavis, Soilas, sp. PI. II. Fig. 4. 

 This form has already been recorded by Dr. Soilas, and is 

 mentioned here in passing as occurring in the Gault beds of Folke- 

 stone in Zones IV. VII. and XL at 50 feet from the top.

The test, which is generally found attached to shell fragments, 

 such as Nucula, commences with a polymorphine arrangement of 

 chambers, which proceeds to take on a wild flattened fistulose 

 growth, sometimes six times the length of the initial series of 

 ohambers. The apertures are simple orifices at the terminations of 

 the branchlets. An example occurs in which the branching growth 

 has just commenced. This variety is found in Zones III. and VII. 

 of the Gault at Copt Point. 



In concluding these notes, I wish to acknowledge the kind advice 

 I have received from Prof. T. Kupert Jones, F.R.S., and also the 

 valuable assistance of my friend Mr. C. D. Sherborn, F.G.S.

 slight grooves in the shell to which the Foraminifer was attached, as 

 if the foreign body were partially dissolved along tlie lines of attach-

 of the shell contains an infilling of pyrites (x 30).

IV. — The Absence of Glacial Phenomena in large Parts op 



Western Asia and Eastern Europe, etc. 



By Henry H. Hovvorth, M.P., F.G.S. , etc. 



IN some papers which you have done me the favour to print in 

 the Geological Magazine, I have endeavoured to apply a new 

 touchstone to test the age of high mountain chains and of laud of 

 high elevation, namely, the presence or absence of distinct and pro- 

 minent traces of former glaciation, and I have argued that where 

 such traces are not forthcoming in a very unmistakable manner, 

 Ave are justified in concluding that these highlands have been 

 elevated since the so-called Glacial Period. I have endeavoured to 

 apply the touchstone in question to the Ural and Altai Mountains, 

 to the Thian Shan and Himalaya ranges in Asia, and to the great 

 Cordillera which binds toe-ether the two continents forming; the New
