aration for the new paleontology, which deals with the history of 

 organisms rather than their form and description alone. Mr. 

 Weller has not only opened the way for his own investigation in 

 this direction, but has rendered a great service to all advanced 

 students who are engaged in paleontological investigation. The 

 matter is well arranged and the necessary statistics are given with 

 precision and will enable the student to turn at once to the original 

 sources of information. h. s. w. 



4. Contributions to the Tertiary Fauna of Florida, etc.; by 

 Wm. H. Dall. Vol. iii, Part iv. — I, Prionodesmacea : Nucula to 

 Julia, II, Teleodesmacea: Teredo to Erville; (Trans. Wagner's 

 Free Inst, of Sci. of Philadelphia), pp. 571-947, plates xxiii-xxxv, 

 April, 1898. — This volume maintains the characteristics of its 

 predecessors ; — the beautiful, sharply-defined illustrations and the 

 clear and exhaustive descriptive parts, which are carried out in 

 many cases to a thorough revision of classification of the larger 

 divisions and the distribution of the known species, leave little to 

 be desired in the discussion of such a group of fossil mollusca.

5. Contributions to Canadian Paleontology ; by J. F. Whit- 

 eaves; vol. i, part v, pp. 361-436, plates xlviii-1; Geol. Survey 

 of Canada, No. 659, 1898. — This closing part of the first volume 

 of contributions to Canadian Paleontology is chiefly concerned 

 with the thorough revision of the nomenclature and faunas particu- 

 larly noted in the previous portions of the volume, the first of 

 which was issued in 1885. 



In the first papers, the Hamilton fauna of Thedford, Widder 

 and neighborhood in Ontario is thus revised ; the additions are 

 based upon new collections made by Mr. Schuchert, for the 

 National Museum, in 1895 and Canadian collections examined by 

 the author; and the revision of nomenclature is of particular 

 importance, as expressing the comparative study, of both Mr. 

 Whiteaves and Mr. Schuchert, on large and widely distributed 

 collections. The final list recognizes 226 species in the fauna. 

 The second number of the part is an appendix on revision of 

 nomenclature and statements in previous numbers of the volume. 

 The volume being now complete, a special title page is issued with 

 directions for binding the whole. h. s. w.

 sheet (I), Low's report on the northern part of Labrador penin- 

 sula (L), Bailey's report on S. W. Nova Scotia (M), Hoffmann's

 434 and 510). h. s. w.
