54. During the winter of 1850-51, Prof. C. B. Adams of Amherst College, 

 Massachusetts, visited Panama for the express purpose of making collections 

 for the College Museum, and obtaining exact information on points connected 

 with habitat and station. Although he only remained thirty-eight days on 

 the spot, he collected —
