full particulars of the known mineral resources of the colony will 

 be found. 



There is no doubt that rich gold-fields exist, some of unknown 

 extent, but enterprise has been arrested by the scarcity of water, and 

 the want of railway communication. 



WOODWARDIAN MuSEUM, CAMBRIDGE. CATALOGUE OF THE FOSSILS IN THE 



Students' Stratigraphical Series. By H. Woods. 8vo. Pp. 24 (interleaved). 

 Cambridge, 1893. 



This little pamphlet contains a list of the typical fossils of each 

 formation, together with a note as to their class or order. We recall 

 a collection of a similar nature in the Edinburgh Museum, which has 

 been arranged by Mr. Goodchild, and at the present moment 

 Mr. Etheridge is soliciting specimens for a like purpose in the British 

 Museum. We would suggest that Mr. Woods, in his next edition, 

 might add the authors' names to the species, for it is most important 

 that the student should be trained to associate the literature of the 

 fossil with its name. 



LiEFERUNGEN 7 to 9 of the new edition of the Molluscan portion 

 of Bronn's " Klassen," edited by Simroth, have just lately been 

 received. They contain the completion of the Aplacophora and the 

 first few pages of the Polyplacophora. 



The following is the author's subdivision of the former order so 

 far as the families are concerned : — 



Sub-Order. Family. 



I. Chagtodermatina i. Chsetodermatidae. 



( I. Neoraeniidas 



II. Neomeniina J 2. Proneomeniidas 



j 3. Dondersiidae 

 \^4. Parameniidse 



We regret, however, to notice that new genera, subgenera, and 

 even species are introduced and not always fully described. New 

 forms, even in such a small group as this, should, we venture to 

 think, be previously described elsewhere : their inclusion in the first 

 instance in a work of this character, where they are out of harmony, 

 is a mistake, and unnecessarily complicates the subject-matter, 

 which should be kept strictly to its proper broad lines. 



Very useful to students of Ammonites is a pamphlet by Dr. J. F. 

 Pompeckj (Beitrage zu einer Revision der Ammoniten des Schwabi- 

 schen Jura. Lief. i. Stuttgart: E. Schweizerbartsche Verlagshand- 

 lung, pp. 1-94, pis. i.-vii., 1893). This is nothing less than the 

 translation of the remarkable trinomial and sometimes quadri- 

 nomial nomenclature, employed by Quenstedt in his great works on 

 Ammonites, into the modern system. Thus, Ammonites angnlatns 

 intermedins gigas, as Quenstedt named one important species, is 

 concisely rendered mto Schlotheimia intermedia. The present part 

 deals with the genera Phylloceras, Psiloceras, and Schlotheimia ; and 

 besides the translation of its name, each species is critically con- 

 sidered, and mistakes in identification corrected ; while new species 

 of Swabian Ammonites are described. Future instalments of the 

 work will be awaited with interest. We only hope that the author 

 will not treat Arietttes, which he incidentally mentions, as a valid 

 genus. It is forestalled by Hyatt's Arniocevas, Coroniceras, etc., whose
