Coast of Brazil. Latitude 19° to 21° South. 



The material for this zone docs not belong exclusively either to the one tnat precedes or to the 

 one that follows, the limit between the two being .the parallel of latitude 20°. It is thought best, 

 therefore, to arrange it in a zone by itself. It embraces an aggregate period of nearly 3 years, and 

 was collected and classified at the United States Naval Observatory, under the direction of Capt. 

 M. P. Maury, Superintendent.
