II. — MONOGKAPHS PUBLISHED BY THE PaL^ONTOGKAPHICAL SoCIETY, 



Vol. XX. 1867. 



IN the G-EOLOGiOAL Magazine for Marcli, 1867, p. 122, we 

 " recorded the issue (in December, 1866), of the 19th volume 

 published by this Society,, being that due to its members for 1865. 

 By the energy and zeal of the Eev. T. Wiltshire, M.A., F.G.S., the 

 Honorary Secretary, another fasciculus has just been issued (June, 

 1867), being the volume for 1866. We learn that the volume for 

 1867 is in the press, and will be ready by October or November. 



Vol. XX. contains the following Monographs: — I. Part IV. 

 No. 1. Of the British Fossil Corals (2nd Series), by P. Martin 

 Duncan, M.B., Lend., F.G.S.—II. Part IV. Of British Trilobites, by 

 J. W. Salter, A.L.S., F.G.S.— III. Part Vn. No. 2. Of British 

 Fossil Brachiopoda, by Thomas Davidson, F.E.S., F.G.S. — IV. Part 

 III. Of the British Belemnitidee by Professor John Phillips, M.A., 

 LL.D., D.C.L., etc. etc. 



I. Dr. Duncan gives us an account of the Liassic corals found 

 in the zones of Ammonites planorbis, and A. angulatus ; and belonging 

 to the following genera : — 1. Montlivaltia ; 2. Bhabdophyllia ; 3. 

 Thecosmilia ; 4. Oppelosmilia ; gen. nov. 5. Isastrcea; 6. Astrocce- 

 nia ; 7. Cyathoccenia ; gen. nov. 8. Elysastrcea ; 9. Septastrcea ; 10. 

 Latimceandra. In all 10 genera and 48 species. These are illus- 

 trated by eleven tinted and black -background plates, well executed 

 by Mr. Gr. E. de Wilde. The importance of Dr. Duncan's Mono- 

 gi'aph may be readily seen when it is stated that only one good 

 species of Coral, the Trochocyaihus Moorei, Ed. and H., had before 

 this been determined from the British Lias. 



II. Mr. Salter contributes six plates, one of Ogygia and five of 

 Illcenus. He gives an account of the new genus Barrandia longifrons 

 from the pen of the late H. Wyatt-Edgell, Esq., and describes 16 

 species of Illcenus, 2 of Illienopsis, 2 of Ogygia, and begins the 

 family of the Bronteidce. We hope and trust that the health and 

 leisure, about which Mr. Salter seems so doubtful, may be granted 

 him to complete this grand work, a bird's-eye view of which he 

 gives us in his " Notice to Correspondents." 



in. The untiring iadustry and genius of Mr. Davidson have 

 enabled him to add another charmingly-illustrated part to his mono- 

 graph of Silurian Brachiopoda, The single-minded devotion of 

 Mr. Davidson's attachment for the " Lamp-shells," is a sermon to 

 all aspirants for Paleeontological honours ; it says plainly, " Don't 

 have too many irons in the fire." The writer remembers hearing 

 the late Dr. Falconer observe to a yoimg Naturalist, " Never mind, 

 my young friend, how narrow the groove you run in, only take care 

 to stick to it." 



Mr. Davidson's part is illustrated by ten well-filled plates, illus- 

 trating Meristella, Aihyris, Betzia, Atrypa, Pentamerus, Striclclandinia, 

 Bhynchonella, and Merista or Camarium. 



IV. Professor Phillips continues his history of the British Belem- 

 nitidce, and adds thirteen more plates, well drawn, and printed on a
