7. A Students Text-Booh of Zoology, Vol. II ; by Adam 

 Sedgwick. London : Swan Sonnenschen & Co. New York : 

 Macmillan Co. 705 pp., 333 cuts. — The second volume of this 

 excellent text-book has been received. It includes the true Ver- 

 tebrata and Cephalochorda. These are treated with unusual full- 

 ness both systematically and anatomically, and are well illustrated, 

 though a large part of the cuts are the same as those used in the 

 well known work of Claus. About fifty cuts are new. In the 

 case of fishes the somewhat old classification of Gunther has been 

 followed. Many later improvements in that group might well 

 have been adopted. On the whole, it is the best text-book on the 

 morphology of the Vertebrata now available. a. e. v. 



8. A Preliminary Report on the Protozoa of the Fresh Waters 

 of Connecticut ; by Herbert William Conn. Bulletin No. 2, 

 Connecticut State Geological and Natural History Survey. 69 pp., 

 34 pis., 1905. — This report deserves more than a passing notice 

 because it is the first attempt yet made to enumerate and illus- 

 trate all the unicellular animals found in any locality in America. 

 As implied by the title, the present report is but the beginning of 

 an extensive work, in which it is aimed to eventually include a 

 general study of all the Protozoa found in the State, with a con- 

 sideration of their habits, evolution, geographical distribution, 

 and their economic relation to the purity of drinking waters. 

 The preliminary work for such a study must be the identification 

 of the species, and to aid microscopists in recognizing the forms 

 already found the present report is provided with 303 figures, all 

 of which are from original drawings by the author from speci- 

 mens collected in the State, and include every species which the 

 author has thus far recognized in the region. No attempt has 

 been made to give names to the new genera and new or unidenti- 

 fied species which are thus illustrated, such forms being desig- 

 nated merely as " new genus " and " sp. (?)" respectively. In the 

 final report it is intended to furnish generic and specific diag- 

 noses of all these forms, but the present work is provided with a 

 brief description of the recognized genera only, specific descrip- 

 tions being wholly omitted. There are admirably arranged keys 

 to orders and genera. The figures are remarkably well drawn, 

 and are printed in such a manner as to reflect great credit on the 

 officers of the Survey, as well as on the author. The excellence 

 of these plates is in striking contrast with the character of the 

 illustrations published in the majority of State reports in recent 

 years. 



The value of this work will go far in justifying the inaugura- 

 tion of the newly established Geological and Natural History 

 Survey of the State and forms a worthy leader of its series of 

 zoological publications. w. r. c.
