FISH IN THE DEVONIAN (NOT OLD RED) ROCKS. 



Mr. Pengelly has the pleasure to inform Mr. Salter, in reply to 

 the queries contained in his letter which appeared in the Geological 

 Magazine for March last (p. 134), that the information he desires 

 has already been published in the Eeports of the British Association 

 for 1862, Trans. Sec, p. 85; in the Geologist, vol. v. p. 456 ; and in 

 the Trans. Eoy. Geol. Soc. of Cornwall, vol. vii. p. 441. The 

 specimen (which consists of a single scale of Phyllolepis) is in 

 Mr. Pengelly's private collection. 



It was seen and examined by the late Dr. S. P. Woodward, and 

 by Professor Owen, and identified by Mr. W. Davies as the PMllo- 

 lepis concentricus, of Agassiz, with the figure of which species it 

 agrees well. 



The fossil was found by Mr. Alfred Pengelly in the gritty slate, at 

 the foot of the cliff, between Meaford beach and Hope's Nose, Torbay. 



Mr. William Pengelly was present, and assisted his son in ex- 

 tracting it from the matrix. 



LITHODOMOUS PERFORATIONS IN LIMESTONE CLIFFS. 



With reference to Mr. D. Mackintosh's letter on Denudation, — 

 which appeared in the Geological Magazine for March, 1867, 

 pp. 136-139, — Mr. Pengelly calls attention to the fact of his having 

 read a paper in Sept. 1864, " On Changes of Eelative level of Land 

 and Sea in South-Eastern Devonshire, in connexion with the anti- 

 quity of man " (which under the title of " Early Man in Devonshire," 

 was printed, nearly in full, in the "Eeader" of Nov. 19, 1864). 



Mr. Mackintosh's earliest paper on Denudation appeared in the 

 Geological Magazine, Vol. II. April, 1865, p. 154, and therefore 

 subsequent to Mr. Pengelly's communication. 



Mr. Pengelly has no doubt the perforations mentioned by him in 

 his paper (quoted above), to which Mr. Mackintosh refers in his 

 letter, were drilled by marine mollusks ; but he has not ventured to 

 refer them to any species of Pholas.
