Foraminifera in the Crag and in some Contemporaneous Formations 

 in Europe" (pp. 374-394), in which the occurrence of 410 genera 

 and species in the several divisions of the Crag, and of the Pliocene 

 of Belgium and of Italy, and one zone in the south of Spain, are 

 carefully compared. 



II. — A Monograph of the British Carboniferous Lamellibx'anchiata, 

 by Wheelton Hind, M.D., etc. Part II, Mytilidse, Arcidre, Nuculidee ; 

 pp. 81-200, pis. iii-xv (1897). The author has devoted time and 

 labour to this useful work. The synonj'raies of the genera and of 

 their many species are good evidence of this ; and the several 

 descriptions show conscientious work. The genera treated of are : 

 Posidomella, De Koninck, 9 species; Naiadites, Dawson (8 species 

 were described in the author's monograph in 1895) ; Myalina, 

 De Koninck, 7 species ; Parallelodon, De Koninck, 22 species ; 

 Nui'ida, Lamarck, 8 species ; Nuculana, Link, 6 species. Plates iii 

 to XV illustrate these forms in abundant detail. 



Part III, pp. 209-276, pis. xvi-xxv (1898). The Nuculid^, 

 continued ; Ctenodonia has one species. Of the Trigonidee [rightly 

 Trigoniidee] we have here Sclnzodus, 4 species ; Protoschizodus, 

 13 species. Of the Unionidee, J.n</iracom^a is the type. Edmondidte 

 supply Cardiomoiyha,'w\\\i 9 species. The illustrations are numerous, 

 and aim at the correct definition of all the features of the shells, 

 both in external and internal aspect. 



III. — A Monograph of the Carboniferous Cephalopoda of Ireland, 

 by Arthur H. Foord, Ph.D., F.G.S., etc. Part I, Orthoceratidge ; 

 pp. 1-22, pis. i-vii (1897). The author had produced a doctoral 

 thesis with these fossils as its theme, and here the descriptions are 

 reproduced with appropriate and good lithograph illustrations of full 

 size. Grouping them as : A. Zongicones ; Group I, Zcevia, and 

 sub-Group Cylindri formes, he describes 12 species ; sub-Group, 

 Moniliformes, 3 species. Of Group II, Annidata, 1 species. Of 

 Group III, Angulata, 1 species. Of Group IV, Lineata, 4 species. 

 Of Group V, Imhricata, 1 species. Most of these are new species. 



Part II (1898) contains the concluding part of the Orthoceratid^, 

 and the families Actinoceratidae, Cyrtoceratid^e, and the Poterio- 

 ceratidse, with 25 pages of letterpress and 10 plates. It is only 

 right to say a word in praise of Mr. A. H. Crowther's excellent 

 and careful lithographic plates of Irish cephalopods, drawn under 

 Dr. Foord's own eyes in Dublin, as they are certainly among the 

 best illustrations which the volumes contain. Dr. Foord's wide 

 experience in the study of Cephalopoda in Canada, in the British 

 Museum, and now in Dublin, renders his monograph of great 

 scientific value to palceontologists. 



IV. — A Monograph of the Devonian Fauna of the South of 

 England, by G. F. Whidborne, M.A., F.G.S., etc. Vol. iii, pt. 2 : 

 The Fauna of the Marwood and Pilton Beds of North Devon and 

 Somerset (continued) ; pp. 113-178, pis. xvii-xxi (1897). Some 

 further results of the Kev. G. F. Whidborne's enthusiastic researches 

 among the relics of an old Devonian fauna, badly preserved by 

 nature in the strata of Devonshire, are here given.
