To us it seems that the desirability of this change is very question- 

 able. To make up for this, Dr. Giinther reunites his Pristipomatidse 

 with the Serranidae. 



Before taking leave of this book we must say a few words as to 

 the illustrations. Mr. Ford's power of representing fishes is so 

 well known that it is almost a work of supererogation to say that 

 these figures of South-Sea fishes are beautifully drawn ; and, in fact, 

 the structural details are represented with a delicacy and accuracy 

 which leave nothing to be desired. But in most cases the plates are 

 worked in colours ; and these have generally been most admirably 

 managed, the brilliant and delicate tints of the beautiful Basses and 

 Apogons coming out wonderfully, and rendering the mere contem- 

 plation of the plates a real gratification. We look forward with 

 pleasure to the continuation and completion of this most valuable 

 work, which will form a worthy monument at once to the talents 

 and industry of the author and artist and to the liberality of the 

 founder and supporter of the Museum Godeffroy. 



The Recent and Fossil Foraminifera of Belgium. By MM. H. J. 

 Miiler and E. Vanden Broeck. (Les Foraminiferes, $x.) 8vo. 

 pp. 34 and Tables. Brussels, 1873. 



This memoir, reprinted from the 'Annals ' of the Malacological 

 Society of Belgium, is the first part of an intended monograph of the 

 .Foraminifera of Belgium. It consists partly of an Introduction, 

 treating of the gradual progress made by naturalists in the study of 

 these Rhizopods, and more particularly of what is known of the 

 presence of fossil Foraminifera in the several Belgian formations 

 from the Lias to the Pliocene inclusive. Thus, in the Lias (Lower) 

 there are 11 species known ; in the Aachenian stage of the Creta- 

 ceous system, ; in the Hervian, 11 ; Nervian, 1 ; Senonian, 92 ; 

 Maestrichtian, 76. In the Tertiary Montian and Heersian, ; 

 Landenian, 6 ; Ypresian, 11 ; Paniselian, 1 ; Bruxellian, 3 ; Laeke- 

 nian, 9 ; Tongrian, 1 ; Rupelian, 4 ; Bolderian, ; Diestian, 70 ; 

 and in the Scaldisian, 8. 



Part L, on the existing Foraminifera of Belgium, follows, com- 

 mencing with a list of littoral species collected at Sluys-Kill, 

 Ostend, and Nieuport. The first-named place is a little beyond the 

 frontier, on a shallow sea-creek full of animal and vegetable life, 

 and swarming with Foraminifera, the different groups of which at 

 different depths and localities can be reached by wading, and col- 

 lected separately. Our authors have detected many fossil specimens, 

 derived from neighbouring Diestian and Scaldisian strata, among 

 the recent fauna ; and they have given a list of them (p. 27), in 

 which they have had the aid of Messrs. Jones and Parker. Sluys- 

 Kill typifies the muddy littoral zone ; whilst the sandy zone is to be 

 studied at Nieuport, Ostend, Blankenberg, BTeyst, and along the coast 

 generally. On the sand zone strong shells of Polystomella crispa, 

 Rotalia Beccarii, Triloculina oblonga, Quinqueloadina bicornis, &c. 

 are common ; whilst the delicate Lagena Icevis, L. sulcata, Poly-
