 species in these families." 



1882. Mr. R. Etheridge, jun., gave the opening address before the Royal 

 Physical Society of Edinburgh on November 16th, 1881, entitled " The Palgeozoic 

 Conchology of Scotland." In it he summarised the knowledge then attained of 

 the Carboniferous Lamellibranchiata of Scotland, with very valuable but brief 

 remarks on each family and genus, and their systematic position in the general 

 classification of the group, with a short discussion on the value of each 

 division. 



1882. On June 23rd, 1880, Mr. Kirkby read a paper before the Geological 

 Society, published in No. 144, vol. xxxvi, p. 559, of the ' Quarterly Journal,' 

 " On the Zones of Marine Fossils in the Calciferous Sandstone Series of Fife.'* 

 At the end of this paper (p. 583) are " Notes on the Species," in which the 

 following forms are discussed, but no figures are given : 



Avicula recta, M'Coy 

 Cypricardia bicosta, sp. nov., 

 Myalina modioliformis , Brown, 

 Sanguinolites Abdenensis, Etheridge, 



Sanguinolites suhplicatus, sp. nov.

 Pleuropliorus elegans, sp. nov., 



with a table showing the vertical range of each of these, with other fossils.

1882. Dr. Hunter gives lists of Carboniferous Lamellibranchiata from the 

 various beds included in his paper on " The Geology and Paleontology of 

 Bankend, Bellfield, and Coalburn, Lesmahagow," published in the 'Transactions 

 of the Geological Society of Glasgow,' vol. vii, for 1882, p. 143.
