Reviews — Dr. G. J. Hinde on Fossil Radiolaria. 29 



"So far as the individual constituent bones are concerned 

 they present resemblances to their homologous parts in both the 

 PhalangeridfB and the Phascolomyida), but the approximation to the 

 former is, on the whole, greater than to the latter. 



"On the other hand, regarding the feet as a whole, they, in their 

 shape and proportions as well as in the character and degree of 

 the attenuation of the second and third digits of the pes, are more 

 readily comparable to these members in the Phascolomyidaj. 



" With the more specialized pes of the MacropodidfB, comparison 

 of that of Diprotodon yields scarcely any points of resemblance, 

 except in so far as the character of the degradation of the hind-feet, 

 similar in kind but varying in degree, affords evidence of the 

 marsupial nature of both." 



The memoir is excellently illustrated by a series of eighteen very 

 good photographic plates, including two of the restored manus 

 and pes.

AMONG the various minute aquatic organisms that have persistent 

 structure within or without their bodies, several kinds have 

 been recognized by naturalists, with more or less exact discrimination, 

 since natural history became a definite study, after the dark ages of
