Reviews — Palceontograjphical Monographs. 217 



I.— Monographs Published by thk Pal^ontogkaphioal Society. 

 February, 1869. Vol. XXII. (Issued for 1868). 



THE pleasant task again falls to our lot to announce the issue of 

 the twenty- second volume of the publications of this Society. 

 We do so with more than usual good-will on this occasion, because 

 the issue of this volume wipes off all arrears due from the Society to 

 its subscribers, and leaves them nearly twelve months in which to 

 produce the volume due to its members for the current year's sub- 

 scription. 



The present fasciculus of Monographs is made up of : — 



1. Supplement to the Fossil Corals, Part ii., No. 1. Corals from 

 the White Chalk, the Upper Greensand, and the Eed Chalk of Hun- 

 stanton, Plates i.-ix., by P. Martin Duncan, M.B, Lond., F.E.S., 

 F. and Sec. Geol. Soc. The nine plates which accompany this part 

 are by De Wilde. The genera illustrated and described by Dr. 

 Duncan arc Caryophyllia (3 species) ; Onchotrochus (2 species) ; 

 Ccelosmilia (6 species) ; Parasmilia (3 species) ; Dihlasus (1 species) ; 

 Smilotrochus (4 species) ; Gyathopora (1 species) ; Favia (1 species) ; 

 Thamnastrcea (1 species) ; Cyclolites (1 species) ; Podoseris (2 species). 



2. Fossil Crustacea — Order Merostomata, Part ii. Pterygotus 

 bilobus, by Henry Woodward, F.G.S., etc. This includes four 

 varieties, viz., inornatus, crassus, perornatus, and acidens, illustrated 

 with six plates by HoUick and Fielding. The specimens described 

 in this part are all from Lesmahagow in Lanarkshire, and give us 

 most complete details of structure, a rare occurrence in Silurian 

 fossils. 



3. Fossil Brachiopoda, Part vii.. No. 3, of the Silurian Brachio- 

 poda, by Thomas Davidson, F.E.S., Plates 23-37. Containing Bhyn- 

 chonella (16 species) ; Orthis (52 species) ; Triplesia (3 species) ; 

 Atrypa (2 species) ; Cyrtia, Eichwaldia, Porambonites, and Stro- 

 phomena ; illustrated in all by 390 figures ! 



It affords us great pleasure to know that Mr. Davidson is once 

 more returned to England, and we hope his health and strength may 

 be spared to finish this grand monograph, which is all Ms own. 



4. The Liassio and Oolitic Belemnitidce, Part iv., by Professor 

 Phillips, M.A., LL.D., F.E.S., etc., Plates 21-27, with descriptions 

 and illustrations of sixteen species. Geologists in the Oolitic and 

 Liassic districts will rejoice to secure this work, for of all difficult 

 things to deal with, in the way of determining their species, the 

 guards of Belemnites are the most so. The Plates for this mono- 

 graph continue to be drawn and printed in Paris. Those of B. ellip- 

 ticus, B. Aalensis, and B. giganteus, are particularly effective and 

 bold. 



5. Professor Owen contributes No. III. to his Fossil Eeptilia from 

 the Kimmeridge Clay, in which he describes and figures : Palatal 

 surface of skull and upper surface of lower jaw of Pliosaurus grandis, 

 and part of cranium and lower jaw of Pliosaurus trochanterius, both
