I. — On some Characters of Lingula anatina, illustrating 

 the Study of Fossil Palliohranchs. By WlLLlAM KlNG, 

 Sc.D., Professor of Mineralogy and Geology in the Queen's 

 University, Ireland, and Queen's College, Gralway. 

 [Plate II.] 



The investigations which have led to the preparation of the 

 present paper were begun with in order to ascertain the 

 relationship between Lingula and Trimerella — a point which 

 Mr. Davidson and myself considered necessary to be deter- 

 mined before completing the memoir we have in hand on the 

 family typified by the last-named genus *.

I much regret that, owing to the distance by which we are separated, it 

 was impossible for my Mend and colleague, Mr. T. Davidson, F.R.S., to join 

 with me in the investigations detailed in this paper. He has, however, 

 aided me to such an extent that had it been otherwise the paper certainly 

 would never have appeared. After much correspondence and trouble, he 

 at last succeeded in procuring a number of specimens of Lingula anatina 

 preserved in spirits. Some were supplied by Dr. L. de Koninck, Pro- 

 fessor in the University of Liege ; and others by Dr. C. Semper, Professor 

 in the University of Wiirzburg, Bavaria, and Dr. G. Lindstroin, of 

 Wisby, Gothland. To these gentlemen we join in recording our sincere 

 thanks for their kind favours. We also feel it necessary to acknowledge 

 our obligations to Prof. A. E. Verrill, of Yale College, for his valuable 

 present of a bottle containing several fine specimens of Discina lamellosa 

 and Terebrattdina septentrionalis. These specimens have greatly assisted 

 me in my researches on Linc/ula.
