THE AMERICAN NATURALIST [Vol. XLIV 



final purpose a complete investigation of the geographical dis- 

 tribution of fresh water fishes in South America, and the rela- 

 tion of the barriers separating river basins to the development 

 of new species. The first of these reports by Dr. Eigenmann 

 gives new genera and species of fishes in British Guiana. A 

 remarkable feature of this investigation is the discovery that 

 almost all types of fishes found in different species in North 

 America are represented in South America by analogies be- 

 longing to the family of Characida?. Thus, minnows, chubs, 

 suckers, darters and perches all have their representatives in a 

 family which is not represented by any of these, but which prac- 

 tically monopolizes the waters of South America. 



The second of these reports, by Marion Lee Durbin, describes 

 one new genus and twelve new species of ctiaracins. 



In the third report, Mr. Christian B. Blosser describes fishes 

 obtained, most of them incidentally, in the West Indies and on 

 the coast of Guiana. The following are new species : Apogon- 

 ichthys mdcunpodus, from St. Croix; Bodianus sfellatus, from 

 St. Croix; Holoranihus lunatus. of St. Croix ; Sphcroidcs astcrias, 

 St. Croix. Chr<j»iis maryiuatxs, a species not previously found 



In the Proceedings of the Royal Society of New South Wales, 

 1908, Ogilby and McCulloch offer a revision of the Australian 

 Oretolobidte, group of carpet-sharks, some of them known locally 

 as wobbegongs. 



In the Records of the Australian Museum, Allan R. McCulloch 

 publishes studies in Australian fishes. No. '2, with descriptions of 

 a number of new or rare species from about Sydney. 



In the Ann. Mas. Zool. of St. Petersburg, Volume 14, 1909, 

 Dr. Leo S. Berg demonstrates the distinctness of the genus 

 Acanthogobio from Hemibarbus. 



In the same publication. Dr. Berg discusses the trout of the 

 Sea of Aral, Salmo trutta aralensis. 



In the same bulletin, Dr. Berg discusses the salmon of the 

 Black Sea, Salmo solar labrax. 



In the same bulletin Dr. Berg gives a list of the fishes of the 

 River Ob, or Obi, forty-two in number. 



In a publication of the Provincial Museum of Natural History 

 and Ethnology, at Victoria, British Columbia, 1909, Mr. Francis 

 Kermode, curator, gives a list of the animals represented in the 

 collection, with excellent photographs of many of the species 

 of fish, as well as of birds, totem poles and other objects of
