Haseman : KxPEDi iioN TO Central South America. 2<Si> 



.■^. An increase in the niinil)i'r of fislu-s reported from the Sao 

 Francisco Ri\'er. 



4. The determination that the fishes of tlic Itapic iiri'i are nearly 

 all found in the Sao I''rancisco Ri\er. 



Journey No. 2. Along the Coast North of Bahia. The hitter part 

 of March and the first two weeks of April, IQ08. 



From Bahia I sailed up the coast to the mouth of the Rio Sao 

 Francisco, in order to collect fishes below the large Paulo Affonso 

 Falls. I went uj) to them and found that during heavy floods fishes 

 might pass the Bahian branch of the falls. 1 returned to the mouth 

 of the river and went \\\^ the coast to Pernambuco. However, the 

 long dry season made work in this section of Brazil almost futile. 

 Therefore I returned to Bahia, collecting as I traveled. The most 

 important result of this trip was the discovery that it is possible 

 for fishes to pass the Falls of Paulo Affonso. 



Journey No. j. To the Waters about Rio de Janeiro and Sao Paulo. 

 From April ig to first week of November, igo8. 



I left Bahia for Rio de Janeiro on April 19. and, after six days of 

 necessary delay in Rio, went to the headwaters of the Rios Sao Fran- 

 cisco. Docc, and Grande of the Parana basin. On the return I 

 collected in the lower courses of the Rio Parahyba, Lagoa Feia. and 

 Rio Itapemirim. The chief result of this trij) was the discovery 

 that the Gymnotidcc are represented in the coastal streams of eastern 

 Brazil. I returned to the Parahyba and went across the divide to 

 the headwaters of the Rio Grande. Then I proceeded up the Para- 

 hyba River and crossed over the divide to the Tiete basin and down 

 the same to Sao Paulo. From Sao Paulo I went to various places 

 near Santos. After returning to Sao Paulo I proceeded to the Para- 

 nahyba River near Araguary and back to Bebedouro, Piracicaba, 

 and down the Rio Tiete to the upper Rio Parana. I returned to 

 Bauru and went over to Salto Grande de Paranaponema. These 

 trips were undertaken with a \iew to ascertaining the relation of the 

 distribution of the aquatic life to the various waterfalls in the ujiper 

 Rio Parana and its afiUients. I returned to Rio de Janeiro in No- 

 vember. The chief results of these excursions were: 



1. The addition of many species, heretofore known and described, 

 to the fauna! list of the region. 



2. The knowledge that fishes can pass practically all of the water- 

 falls during big floods.
