each district must be examined by itself. At least sucTi has been ray 

 experience in the Bermudas, the Bahamas, Cuba, Florida, the West 

 Indies, the Sandwich Islands, and Australia. The results of this trip 

 show plainly that Darwin's theory is not applicable to the Fiji 

 Islands, notwithstanding: the borinsfs at Funafuti, and that, iu ail 

 the cases I have examined, the reefs form but a thin crust upon the 

 underlying base, the shape and composition of which is not in any 

 way due to the growth of corals of the existing period." 



It is only possible to allude to the clearness and excellence of 

 execution of the charts and the beauty of the illustrations. The 

 work will be sought after and appreciated by all who are interested 

 in the great question of the origin and the formation of Coral Eeefs.

I. — The Pal^ontogkaphical Society of London : Annual 

 Volumes (li and lii) for 1897 and 1898. Issued to subscribers 

 of one guinea annually, paid on 1st January to the Hon.

THE fiftieth volume issued by this Society, for the year 1896, was 

 reviewed by us in March, 1897 (see the Geol. Mag., 1897, 

 Dec. IV, Vol. IV, No. 393, pp. 134-8). Since that date, vols, li (for 

 1897) and lii (for 1898) have been issued to subscribers, and vol. liii, 

 for the present year, might appear at any moment, having already 

 gone to the printers. 



The salient points of the monographs contained in the last two 

 years' volumes may now be briefly touched upon. 



I. — The fourth (concluding) part of the Monograph of the 

 Foraminifera of the Crag (1897) has been written by T. Rupert 

 Jones, assisted by his highly competent allies, Messrs. H. VV. Burrows, 

 C. D. Sherborn, F. W. Millet, and F. Chapman, who have long 

 been authorities on the history of the Microzoa forming the subject 

 of this monograph. This Part (pp, vii-xv, 315-402, woodcuts 

 24-30 ; there are seven plates in the foregoing Parts I-III, and their 

 figures are largely elucidated in this last Part) treats of some of the 

 Eotalian group, and all of the known British Nummulinidse, including 

 several Nonioninis and Polystomellce, and some representatives of 

 Amphistegina, Operculina, Nummulites, and Orbitoides, but the 

 specimens of the four latter genera have probably been derived from 

 older strata and left in the Crag of Sussex, whence they were 

 obtained. The whole series of Foraminifera as known fossil in the 

 English Tertiaries is thus completed, as begun in Part I (1866), but 

 restated and continued in Part II (1895) and Part III (1896). 

 Having been carefully collated with past and current rhizopodal 

 literature, this well-illustrated monograph must prove to be a valuable 

 guide to further research. Geologists will fully appreciate Messrs. 

 Burrows and Holland's elaborate " Table of the Distribution of the
