4. " On a New Species of Coccodus (C. Lindstromi, Davis)." By 

 J. W. Davis, Esq., F.G.S. 



A description is given of a small fossil fish from the hard chalk 

 of Hakel in Mount Lebanon ; it is nearly related to Coccodus armatus, 

 Pictet, but is smaller than that species, does not show an equivalent 

 of the pectoral spine (unless the posterior extension of the scapular 

 arch should be so considered), and the posterior basal extension of 

 the dorsal spine is very different in the two forms. Further, the 

 dorsal spine is nearer to the occipital region in the new form than 

 in C. armatus, and is, compared with the size of the fish, a larger fin. 



The arrangement of the fins shown in the specimen now described 

 is quite different to that of the Siluroids (Synodontis and Pimelodus), 

 and the great resemblance of the teeth of Coccodus to those of the 

 Pycnodonts, and the cartilaginous character of the vertebra, indicate 

 a relationship with the Ganoids ; but its exact relationship in that 

 group must remain still problematical. 



The author proposes to name the new form Coccodus Lindstromi. 



II.— June 4, 1890.— Dr. A. Geikie, F.E.S., President, in the Chair. 



The President referred to the sad loss which the Society 

 had sustained through the death of Mr. Dallas, and read the 

 following resolution, which had been passed by the Council and 

 ordered to be entered upon its Minutes : — 



" The Council desires to record on its Minutes an 

 expression of its deep regret at the death of the Assistant- 

 Secretary, Mr. Dallas, which took place on the 29th 

 ultimo, and of its sense of the loss inflicted on the Council 

 and Society by the removal of one who, for the long 

 period of twenty-two years, had done them invaluable 

 service, and who, by his courtesy, kindliness, and help- 

 fulness had endeared himself as a personal friend to the 

 Fellows." 



It was moved by Dr. Evans, seconded by Dr. Hinde, and 

 carried unanimously, that the resolution passed by the Council 

 be communicated to Mrs. Dallas on behalf of the Society 

 also. (See Obituary, p. 333.) 



The following communications were read : — 



1. " As to certain ' Changes of Level ' along the Shores on the 

 Western Side of Italy." By R. Mackley Browne, Esq., F.G.S. 



After noticing the prevailing opinion that such changes as he 

 treats of were caused by earth-movements of elevation and depression, 

 the author suggests that the altered levels were due to altered 

 conditions of the Mediterranean. He brings forward objections to 

 the prevailing theory, and remarks on the possibility of periodical 

 oscillating alterations in the tidal depth of the ocean.
