lithina, which must be divided into two orders : {a) Grapto- 

 loidea, {b) Dendroidea. 



" It is noteworthy," she remarks, " that whereas the 

 Graptoloidea seem to develop and change with somewhat 

 starthng rapidity, the Dendroidea appear to change scarcely 

 at all, as regards their fundamental plan, throughout the 

 greater part of Palaeozoic time. . . . Therefore, in considering 

 the question of the evolution of the group as a whole, it is 

 with the Graptoloidea that we are specially concerned, and it 

 is with the members of that order that the present paper deals." 



The sections on the development of the embryo and on the 

 stratigraphic value of evolutional stages will afford food for 

 thought for many. A number of diagrams illustrating the 

 various types add materially to the usefulness of this most 

 admirable " Study in Evolution." 



Dr. W. Leche, in a very suggestive memoir (" Morpho- 

 logische-Geographische Formenreihen bei der Saugetiere," 

 Lund's Universitets Arskrift N.f. Ard. 2, Bd. 16, No. 10, 1921), 

 discusses a number of mammalian families, living and ex- 

 tinct, in which the oriental forms are shown to be more primi- 

 tive than the occidental. He elaborates his arguments, as 

 in the case of the porcupines for example, very ingeniously 

 and convincingly. His conclusions agree very closely with 

 those of Dr. Knud Andersen, based on the study of the Rhino- 

 lophidae among the Chiroptera. Andersen's work, indeed, he 

 is careful to point out, suggested his own researches. All 

 geologists and palaeontologists must read this survey. 



Dr. C. W. Andrews' short paper on the bear of the Forest- 

 bed {Ann. & Mag. Nat. Hist.) shows that this is not identical 

 with the Cave-bear, as is commonly held. This is further 

 and welcome evidence that the forest-bed fauna is entirely 

 distinct from the later Pleistocene and recent faunas, a con- 

 clusion already advanced by Dr. Forsyth-Major, and Mr. 

 M. A. C. Hinton, at different times and places. 



Palaeontologists and zoologists alike will welcome the final 

 instalment of M. Revilliod's very valuable monograph of the 

 Tertiary Chiroptera (" Contribution a I'etudes des Chiropteres 

 des Terrains Tertiares," Mem. Soc. Pal. Suisse, Part HI, xlv, 

 1922.)

In the latest issue of the Journal of the Royal Anthropological
