5. Monograph of the Isopods of North America. Bulletin 

 of the IT. S. National Museum, No. 5Jf.. By Harriet Richard- 

 son. 8vo, 727 pp., 740 text cuts. 1905.— This is a complete 

 monographic work on this group of Crustacea. All the genera 

 and species, as well as the larger groups, are well described and 

 nearly all the species are illustrated, most of the drawings having 

 been made by the authoress. Analytical tables are given for the 

 larger genera. The work is a very valuable contribution to 

 American marine zoology. v. 



6. An Account of the Crustacea of Norway. By G. O. Saks. 

 Bergen. Published by the Bergen Museum. — We have received 

 parts XI and XII of Vol. V of this extensive monograph, includ- 

 ing parts of the families Thalestridse and Diosaccidae of the Cop- 

 epocla. Like all the previous parts, it is profusely illustrated by 

 autographic plates drawn by the author, whose skill and industry 

 are truly marvelous. This work is of great importance to Amer- 

 ican naturalists, for large numbers of the species and genera are 

 found also on the American coast. v. 



7 Mir ds of the Southern Lesser Antilles. Proc. Boston Soc. 

 Nat. History, Vol. XXXII, No. 7, pp. 203-312. 1905. By Austin 

 H. Clark. — This includes a brief general account of the physical 

 conditions of several of the islands, as related to the avifauna, 

 and some facts relating to the recent destruction of many of the 

 birds by hurricanes and volcanic eruptions. It gives a pretty full 

 catalogue of the birds, especially of Barbados, St. Vincent and 

 Grenada, but little is said of those of Dominica. v. 



8. Additions to the Avifauna of Dominica. Notes on species 

 hitherto unrecorded, ivith descriptions of Three New Species and 

 a list of cdl Birds note known to occur on the Island • by A. Hyatt 

 Verrill. Oct., 1905. Published by the author. Rosseau, 

 Dominica. — In this brochure 72 species are added to the fauna of 

 Dominica, making the total number now known 135. The greater 

 number of additions are, of course, migrating species. The new 

 species are Thalurania belli (a humming bird) ; JButeo rivierei; 

 and Setophaga tropica, a native redstart allied to S. ruticilla. 

 This paper forms a useful supplement to that of Mr. Clark, pre- 

 viously noticed. v. 



9. Beitrage zur chemischen Physiologic, herausgegeben von 

 F. Hofmeister. VII. Band. Braunschweig, 1906 (Verlag 

 von F. Vieweg und Sohn). — Of the forty-six communications 

 included in the latest volume of the Beitrage a large number are 

 devoted to studies of enzymes and their activities. A series of 

 papers by Volhard's pupils in Giessen discusses lipolytic reac- 

 tions, particularly their probable occurrence in the stomach. 

 Special mention may be made of an interesting attempt (by Ober- 

 mayer and Pick) to study digestive proteolysis by a new method 

 involving a determination of the changes in the refractive power 

 of solutions at various stages of hydrolysis. Several papers (by 

 Becker, Reichel and Spiro) deal with the nature of the action of 

 rennin. The role of colloids and their physico-chemical changes 

 in certain biological processes also form subjects of investigation 

 in papers by Meyer, Pauli, Mayr, and Reiss. In the domain of 

 metabolism the fate of aliphatic amino-acids has been investi-
