The specimen to which the Author's attention was obligingly 

 drawn by Mr. C. Davies Sherborn, F.G.S., is in the Museum of the 

 Geological Society, and was obtained by Major Newbold, and 

 named in 1846 in MS. by the late Mr. J. de Carle Sowerby, Calais 

 Newboldii, who added on the label : — " Ceph. Octopoda. Genus 

 ineditum. Abdomen alis triangularibus instructum. E. strato 

 calcareo (tertiario) Montis Libani a (D.) Newbold effossum. — 1846. 

 J. de Carle Sowerby." 



The Author described the specimen in detail, and retained for it 

 the genus and species proposed by Mr. Sowerby. 



4. " On Transported Boulder-clay." By the Eev. Edwin Hill, 

 M.A., F.G.S. 



The ' mid-glacial ' sands of the cliffs between Yarmouth and 

 Lowestoft are overlain at Corton by Chalky Boulder-clay. But 

 further north than Corton some masses of the same clay occur in 

 the interior of the cliffs, surrounded by the sands in undisturbed 

 stratification, but passing into them by strings and patches such as 

 suggest the melting off of enveloping ice. They have probably 

 been floated and dropped there. 



Again, gravels lying in a valley of Chalky Boulder-clay in West 

 Suffolk (Cock field, etc.), and indicating considerable denudation of 

 the Clay, yet have some patches and sheets of that Clay overlying 

 them as if carried down or slipped down from higher ground. 



This may explain some anomalous positions of Boulder-clay 

 noted by writers. The Lowestoft observations suggest that Chalky 

 Boulder-clay was being manufactured in one locality simultaneously 

 with ' mid-glacial ' sands in another.

A GEOLOGICAL SURVEY OP EGYPT. 



Sir, — When passing recently through Cairo, I was informed by 

 Lord Cromer of the intention of the Egyptian Government to under- 

 take a Geological Survey of that country, and a few details of the 

 proposed work may not be without interest to your readers. I may 

 state in the first place that this survey is to be undertaken 

 independently of any anticipation of the discovery of valuable 

 minerals ; in fact, quite independently of any utilitarian object, but 

 with a desire to advance the interest of science in Egypt, and to put 

 that country in line with other civilized States. At the same time 

 should the survey result in the development of mineral substances, 

 this will be so much gain. The first chief of this new department 

 will be Captain Lyons, K.E., F.G.S., who, as your readers will re- 

 collect, recently read a suggestive paper before the Geological Society 

 of London on Egyptian Geology, 1 and who, while carrying out the 

 duties of his position as an officer of the Egyptian army, has 

 taken advantage of every opportunity to extend his knowledge of 

 the geological structure of the Nile Valley and the adjoining desert
