American Museum of Natural History, Dr. S. L. Tuxen, Zoological 
Museum, Copenhagen and Dr. David R. Ragge, British Museum 
(Natural History) 5 London. I am indebted to Miss Johanna Darl- 
ington, University of West Indies, Trinidad, who sent me living 
atropos from which our culture was started. I collected live speci- 
mens of B. parabolicus and other species (preserved) during Phase C 
of the Alpha Helix expedition to the Amazon in 1967. I thank the 
National Science Foundation for support on the Amazon expedition 
Under Grant NSF-GB-5916. I am grateful to Mr. Samuel Cohen 
for taking the photographs.
