Reuss and Fritsch's Models of Foraminifera. 1861. 



Whilst speaking of Models of Foraminifera, it may not be 

 amiss to notice a more recent series than that of D'Orbigny — 

 namely, a set of one hundred plaster Models prepared at Prague, 

 under the direction of Professor Reuss and Dr. Anton Fritsch*. 

 These Models are 5 ccntim. in length, and are furnished with 

 printed labels. The species have been selected with a view of 

 supplying a perfect series, and at the same time completing 

 D'Orbigny's suite of Models. Although the aim of the authors 

 of this set of Models is to give delineations of a more extended 

 series of types than were known to D'Orbigny, and though the 

 workmanship expended upon them has the advantage in point 

 of skill, it may be doubted whether the species chosen for illus- 

 tration are altogether so apt, or the general result so instructive, 

 as in the earlier series. Of the forms thus illustrated, some 

 have been selected from species already known, and many have 

 been described and figured in one or other of Professor Reuss' s 

 numerous papers on Fossil Foraminifera. The needless multi- 

 plication of genera appears in a striking light in reviewing the 

 nomenclature of this catalogue. We propose, however, merely 

 to give the list of these Models as arranged in the " Catalogue/' 

 with the Number and Locality appended to each ; also a few 

 remarks, when specially called for, and the type to which the 

 form belongs. We leave the order and the classification as we 

 find them, thinking that it may be of interest to some to com- 

 pare the results with the somewhat similar, but less artificial, 

 system which we are in the habit of using, based upon the 

 principles laid down in Dr. Carpenter's "Introduction." 



We have to thank Mr. S. V. Wood, F.G.S., for lending us 

 his set of D'Orbigny's Models during several years, whilst we 

 have been engaged on this Memoir.
