those shells belonging to the family of the Pyramidellidge. By far 

 the larger part of the work (pp. 95-343) is concerned with the 

 mollusca, and here we must congratulate Dr. Arnold on the thoroughly 

 systematic manner in which he has treated this part of his mono- 

 graph, especially with regard to nomenclature, which has evidently 

 received very considerable attention. We, however, would still 

 prefer to adopt Nuculana for Leda, Volsella for Modiolus, Gari for 

 Psammohia, Cvspidaria for Necera, Vohidella for Volvida, and Bullinella 

 for Cylichna. Out of the 37 plates illustrating the volume, 21 are 

 devoted to shells, all admirably depicted by photo-lithography ; the 

 remainder consist of sections, map, and several photographic views 

 of the San Pedro country, exhibiting the Tertiary and post-Tertiary 

 formations, as well as some interesting beach-structures which skirt 

 the Pacific shores of the region in question. An index of specific 

 names, arranged under their genera, concludes this useful and well- 

 compiled work. 



IV. — Catalogue of the Collection of London Antiquities in 

 THE Guildhall Museum. 8vo ; pp. xx, 404, with 100 plates. 

 London, 1903. Price Is. 

 ry^HIS Catalogue opens with an Introduction, which is in brief the 

 JL history of the Collection. It is written by Mr. Charles Welch, 

 who is also responsible for the plan of the work. The Catalogue 

 has been skilfully condensed from the manuscript lists by Mr. G. P. 

 Lawrence, who has added the accessions of tne past three years. 

 Judging by the improvement in the cases during that period, we 

 believe that Mr. Lawrence has done excellent work in the Museum 

 while preparing the Catalogue. Though not of much interest to 

 geologists beyond the flint implements undoubtedly found in London, 

 we call attention to tliis volume because of the quite remarkable 

 way in which it is illustrated. A hundred meisenbach plates, 

 containing 1,100 figures of London antiquities, is undoubtedly 

 a publication of which Londoners and the City Fathers may well be 

 proud, and which cannot fail to be of the greatest interest and utility.

FOSSIL INSECT FROM THE COAL-MEASUEES, NOETH 

 STAFFOEDSHIEE. 

 Sir, — It may be of interest to your readers to know that I lately 

 found a beautifully preserved wing of what is believed to be 

 closely related to Ztthomantis carbonarius (H. Woodw.) in a rich 

 23lant-bed at Foley, near Longton, North Staffordshire. The 

 geological horizon was the Peacock Marl (i.e. the marl overlying 

 the Peacock Coal), and is therefore near the top of the workable 

 Coal-measures. 



I may add that it is the first fossil insect obtained from the 

 Pottery Coalfield, and I am indebted to Dr. H. Woodward, F.K.S., 

 for suggesting the probable name of the specimen.
