Reviews — B ally's British Fossils. 471 



these volumes is a series of photographs of the remarkable trees of 

 Herefordshire, which are deserving of a more general circulation. 



The volume for 1868 contains two fine photographs of Cephalaspis 

 asterolepis and sketches of the unqiue specimen of Stylonurus Sy- 

 mondsii, found at Eowleston Hill, and of Homalonotus Johannis, with 

 descriptions by the late Mr, Salter. There were several interesting 

 contributions on the geology of the neighbourhood sent in during 

 the year, to which, however, we are unable to do more than direct 

 attention. Dr. Bull, who continues his interesting paper on the 

 funguses, explained the discovery of Silurian fossils at Wicton, and 

 the President, Dr. M'Cullough, the characteristics of the Cornstones 

 of Herefordshire and Monmouthshire. Mr. G. Phillips Bevan, 

 F.G.S., read a paper on the South Wales Coal Field, and the Eev. 

 W. S. Symonds, the Pi-esident of the Malvern Naturalists' Field- 

 club, one on the geology of the district. A few palaeontological 

 notes on the Silurian strata of the Woolhope Valley were contributed 

 by the Eev. P. B. Brodie, the Vice-President of the Warwickshire 

 Naturalists' Field-club. Mr. Salter supplied a description of Ptery- 

 gotus tauriniis, discovered by himself and the President in the quarry 

 at Ewyas Harold, near Pontrilas. Papers on British Snakes and 

 Eoman Eoads, Mason Wasps, and Fairy Eings, and a host of other 

 subjects, with reports, meteorological and financial, make up the 

 volume. There is a tendency on the part of some of the authors to 

 indulge too freely, perhaps, in quotations from the Poets, — a practice 

 in the exercise of which too great caution cannot be observed. The 

 contributions are, as a rule, unusually free from errors; in the 

 address of the retiring President for the year 1868, however, we are 

 astonished to find the names of Sir John Lubbock and Professor de 

 Morgan amongst those " of men whom we never again shall speak 

 of as being amongst us." 



VI. — Figures of Characteristio British Fossils, with De- 

 scriptive Eemarks. By W. Hellier Baily, F.L.S., F.G.S., 

 Acting Palaeontologist to H. M. Geological Survey of Ireland. 

 Part II. Plates 11-20. Lower and Upper Silurian. 8vo. pp. 

 43. London : John Van Voorst. 1869. 



WE noticed the first part of this useful work in the Geological 

 Magazine, 1867, Vol. IV., p. 464. Although a long interval 

 has elapsed between the appearance of these parts, Mr. Baily infonns 

 us that he has now made arrangements for its more rapid com- 

 pletion, which we rejoice to hear. The work is so important a one 

 that we are anxious to see more of it ; indeed, it is one which the 

 Palgeontological student must possess for himself, therefore we think 

 it only needs to be made known in order to be sought after and 

 subscribed for. The descriptive letter-press in each part is both 

 palseontological and geological. Commencing in Part I. with the 

 Cambrian rocks, we learn their lithological characters and geo- 

 graphical distribution, and figures are given of recent Hydrozoa for 

 comparison with Oldhamia; and again in the Silurian we have
