PORTRAIT OF DR. JOHNSTON. 



In our Number for September 1855, we gave a short notice of 

 the life and labours of Dr. George Johnston of Berwick-upon-Tweed, 

 who was one of the Editors of this Journal from its commencement 

 to the day of his death. Although so long a time has elapsed since 

 the lamented decease of this distinguished zoologist, we hope that 

 the excellent portrait of him which we have the pleasure of presenting 

 to our readers as the Frontispiece to the present volume of the 

 * Annals ' may not prove unacceptable. Those who were acquainted 

 with the late Dr. Johnston will recognize in it an excellent likeness 

 of that amiable and talented naturalist, in which even the benignity 

 of expression which peculiarly characterized him has been most 

 faithfully preserved. 



The portrait, which is copied from an excellent daguerreotype by 

 Mr. Claudet, taken in 1850, was kindly lent to us for this purpose 

 by Dr. Gray of the British Museum, and has been executed by Mr. 

 Robert Hicks. It is admirably done, and ought to add greatly to 

 the reputation of this talented young engraver. 



On the Occurrence of some new species of PoUicipes in the Inferior 

 Oolite and Lias of Gloucestershire. By the Rev. P. B. Brodie, 

 M.A., F.G.S. 



Mr. Darwin in his valuable and interesting Monograph on the Fos- 

 sil Lepadidae, published in the Memoirs of the Palseontographical 

 Society for 18.51, observes, that "the oldest known pedunculated 

 Cirripede is a PoUicipes^ discovered by Professor Buckman in the 

 Stonesfield Slate." Since the publication of Mr. Darwin's memoir, 

 I discovered the remains of Si PoUicipes in the Inferior Oolite at 

 Selsley Hill near Stroud, in Gloucestershire, a locahty which has 

 afforded many new and interesting fossils, for which we are indebted 

 to the able and active researches of my friend Mr. Lycett. 



Two valves of the scutum are entire, but the other three are too 

 fragmentary to decide to which of the other valves they may have 

 belonged. On comparing the scutum with the same valve in PoUi- 

 cipes ooliticus, of the Stonesfield Slate, there is a marked difference
