THE AMERICAN NATURALIST [Vol. XLII 



contained in the American Museum, with figures of many of 

 the fragments. 



In the Biological Bulletin, Volume 13, Mr. Fernandus Payne 

 describes the effect of light on the blind fish of the Mammoth 

 Cave. In this species the fishes turn away from the light. The 

 young are more sensitive than the adult. The young deprived 

 of eyes are as sensitive as those which have them. They seem 

 to be equally sensitive on all parts of the body, and more sensi- 

 tive to intense light, They seek the dark without regard to the 

 direction of the rays. 



In the Bureau of Fisheries, document 622, Mr. Irving A. Field 

 discusses unutilized fishes, and methods by which these waste 

 species can be rendered of economic service. 



In the American Journal of Anatomy, Mr. William F. Allen 

 describes the blood-vessels in the tail of the garpike, this paper 

 being a continuation of his series of studies of the circulatory 

 system in different fishes. 



In the Procedings of the American Academy of Arts and 

 Sciences, Dr. G. H. Parker describes the sensory reactions of the 

 lancelet. This creature possesses in potentia the sense organs 

 of the vertebrate. It is simple in structure, containing fore- 

 runners of the lateral-line organs, the ear, the temperature or- 

 gans, and doubtless the forerunners of the rod- and cone-cells 

 of the vertebrate retina. It is only slightly sensitive to light, 

 but is sensitive to temperature and to sound. 



In the Journal of Experimental Zoology, Mr. H. H. Newman 

 describes the relation of the hybrids of Fundulus majalis with 

 Fundulus heteroclitus to problems in heredity. The writer 

 thinks that the study of development and heredity are identical, 

 except that the latter is comparative. No two organisms start 

 out from identical germ cells, nor do they ever develop under 

 identical conditions. Instead of a fixity of relationship between 

 pure strains and hybrids, there is constant flux. 



In the Proceedings of the United States National Museum, 

 Volume 33, for 1907, Seale and Bean describe the fishes collected 

 in the Philippines by Major Mearns, with seven new species. 



In the Smithsonian Miscellaneous Contributions, V, 1908, Mr. 

 W. C. Kendall shows that the unrecognized species of whitefish 

 from Saskatchewan Eiver called Coregonus angusticeps by 

 Valenciennes is the chub, Platygobio gracilis. 



In the same Contributions, Dr. Jordan shows the identity of
