POST-TERTIARY ENTOMOSTRACA. 



is entirely different from any group discovered either in the older glacial or the niore 

 recent deposits of Scotland. 



" There are fragments of Valuta Lamherti, Cyprma rustica, Nucula Cohboldia, Fusus 

 contrarius, Purpura incrassata, Nassa elegans, Nassa reticosa, Turritella incrassata, and 

 ^ probably Tro2)lion costiferum, forms unknown either in our glacial beds or in our present 

 sea. Besides these there are the broken remains of many others, of the genera Cardium^ 

 Pecten, Venus, and Astarte, which differ from those found in any of our glacial beds, and 

 one of the most common shells is Pedmculus glycimeris, which attained a large size."^ 



2. KlLMAURS, NEAR IviLMARNOCK. 



Messrs. John Young and Robert Craig have published notes "On the occurrence of 

 Freshwater Plants and Arctic Shells, along with the remains of the Mammoth and Rein- 

 deer, in beds under the Boulder Clay at Kilmaurs/' " 



Since the discovery (18 IG) of the remains of Mepltas ^^rimigenms and Cervus tarandus 

 at Woodhill quarry, Kilmaurs, near Kilmarnock, considerable interest has attached to 

 the beds underlying the Boulder Clay in this neighbourhood. Dr. Bryce has published^ 

 the following section of beds exposed during excavations made under his direction. One 

 of the writers of this paper noted the section in company with Dr. Bryce, and is perfectly 

 satisfied that the sixteen feet of Boulder Clay consist of precisely the same clay as that 

 unfossiliferous Boulder Clay we have described and to which we limit the term. 



1. Carboniferous Sandstone, terminating upwards in beds of sandy clay, 



resembling a fire-clay ..... 



2. Hard gravel, with a little clay, and small bits of round smooth stones, most 



of them quartz and trap, but all free from striation . . 2 ft, 



3. A fine dark-blue clay, with occasionally small bits of quartz and other 



pebbles, extremely distinct in character . . . 9 in. 



4. Sand, irregular in structure, very fine in places and again coarse, 



approaching gravel, very like river-sand . . 6 to 18 in. 



5. Boulder-clay, of reddish-brown colour, very tough and unworkable, full of 



large boulders and smaller stones, mostly smoothed, polished, and 

 striated ; bits of coal-shale, covered with striations, not crushed* , 16ft. 



6. Upper Drift, with stones, but much more open in texture, no striations . 20 ft. 



7. Subsoil and surface soil.
