2. Contributions to the Tertiary Fauna of Florida, with 

 especial reference to the Silex Beds of Tampa and the Pliocene 

 Beds of the Caloosahatchie River, including in many cases a 

 complete revision of the Generic Groups treated of and their 

 American Tertiary Species ; by William Healet Dall. Trans- 

 actions of the Wagner Free Institute of Science of Philadelphia, 

 vol. iii, Part v, pp. 949-1218 ; plates xxxvi-xlvii. Philadelphia, 

 December, 1900. — The present Part, No. V, of Dr. DalPs import- 

 ant contributions to the Tertiary of Florida, includes the genera, 

 from Solen to Diplodonta, of the order Teleodesmacea. It carries 

 the whole so far on towards completion that it is expected that 

 the entire work will be finished in another installment. This 

 part has all the admirable characteristics in substance and method 

 of presentation that have marked its predecessors. The careful 

 and minute critical labor which is recorded here must serve to 

 restore order in the case of a number of groups in which the 

 nomenclature has been hitherto much confused. In addition to 

 the description of the well-known species included within these 

 limits, a very considerable number of new species are given. 

 The illustrations given on the plates with which the part closes 

 are worthy of the descriptive portion of the work and leave 

 nothing to be desired. 



3. A record of the Geology of Texas for the decade ending 

 December 31, 1896 ; by Frederic W. Simonds. (Ex. Trans. 

 Acad. Sci., Vol. III.) Pp. 1-280. 1900.— The value of this 

 Index is greatly increased by the brief summary of contents of 

 each of the volumes cited. It supplements Bulletin 45 of the 

 U. S. Geological Survey (The Present Condition of Knowledge 

 of the Geology of Texas, by Robert T. Hill, 1887), bringing the 

 record down to the close of 1896. w. 



4. Geological Survey of Canada ; G. M. Dawson, Director. 

 General index of the Reports of Progress, 1863 to 1884, (com- 

 piled by D. B: Bowling). Pp. 1-4*75. 1900.—The Reports of 

 the. Geological Survey of Canada prior to 1863, were condensed 

 and summarized in the Geology of Canada, 1863. The present 

 index begins with this volume of 1863 and includes the volumes 

 published up to the Reports of Progress for 1882, 1883, 1884, 

 published in 1884. Its usefulness is apparent. Since 1884 

 " Annual Reports" have been published having their own indices. 

 Special publications and paleontological and botanical reports of 

 the Geological Survey are not indexed in this volume. w. 



5. Report on the Geology and Natural Resources of the 

 Country traversed by the Yellow Head Pass Route from Edmon- 

 ton to Tete Jaune (''ache, comprising portions of Alberta and 

 British Columbia ; by James McEvot. Pp. 1-44 D, PI. I-II, 

 figs. 1-2, 1 map. 1900. — In the region traversed by Mr. McEvoy
