THE AMEBIC AN NATURALIST 



[Vol. XLVI 



much larger number of eggs hatch, and the young are more 

 vigorous than when hatched in the ordinary way. 



If the eggs of salmon are buried beneath five or six inches of sand 

 and gravel, such eggs will hatch and the young will work their way up 

 through the sand and gravel to the surface, and by the time they 

 emerge they have absorbed their sacs and are then exempt from the 

 attacks of vegetable moulds. 



Mr. Babcock thinks that to follow more closely the method of 

 nature will give more value to artificial fishery hatching. 



In the Report of the Fishery Board of Scotland, 1910, Dr. H. 

 C. Williamson gives a valuable report of the reproductive organs 

 of different species of Scottish fishes. 



In the Bull. Zool. Soc. New York Dr. F. B. Sumner continues 

 his study on the changes of color of fishes on different bottoms. 

 The purpose of these changes seems to be simply concealment 

 from their enemies as well as from those fishes on which they 

 prey. 



In Knowledge, Vol. XXXIII, 1910, Rev. T. R. R. Stebbing 

 discusses genders in zoology, sharply criticizing the carelessness 

 with which scientific men have made what he calls "Homeric 

 blunders," Homer being accustomed to nod when questions of 

 classical refinement were brought before him. Mr. Stebbing 

 proposes that in zoology every generic name, whatever its ter- 

 mination, should be recorded as masculine. 



In the Philippine Journal of Science Alvin Seale gives a val- 

 uable account of the fishery resources of the Philippine Islands. 



In the Biological Bulletin Victor E. Shelford gives an inter- 

 esting account of experiments on stream fishes and pond fishes. 



In the Bureaus of Fisheries Document 733 William C. Ken- 

 dall discusses the American fishes, their habits and value. 



In Science, October 11, 1911, Professor E. C. Starks discusses 

 the structure of the air bladder in Ophicephalus. 



In Science, Vol. XXXIII, 1911, Mr. Starks discusses the 

 origin of the gobies. He regards them as somewhat allied to 

 the sculpins. 



In the First Annual Report of the Laguna Marine Laboratory 

 of Pomona College, Claremont, California, are numerous excel- 

 lent papers on the local fauna of Laguna Beach in southern 

 California. Among these papers is an elaborate and well- 

 planned study of the fishes of the tide pools, by Charles W. 

 Metz. The report is accompanied by excellent plates.
