NOTES ON NEOTROPICAL ONYCOPHORA 1 
By Charles T. Brues. 
During the course of the past year I have received for 
identification several lots of Onycophora collected in Panama, 
Colombia, British Guiana and the West Indies. These have 
come from several sources; from the University of Michigan 
Museum collected by F. M. Gaige, from the U. S. National 
Museum collected by W. M. Mann and T. E. Snyder, and one 
from the American Museum of Natural History collected by 
F. E. Lutz. Other examples were obtained by W. M. Wheeler, 
T. Barbour and J. B. Shropshire. 
This material adds considerably to our knowledge of the 
distribution of the group in the American tropics and it contains 
one well marked variety from Panama which has not hitherto 
been described.

There are two females in the collection of the Museum of 
Comparative Zoology, obtained by Dr. Thomas Barbour in the 
Canal Zone, Panama. The species was known by Bouvier from 
Ecuador where it ranges from the sea-coast into the high moun- 
tains at Quito, and has since been reported by Clark from Ancon, 
Canal Zone, Panama. 
The present specimens seem to be referable to 0. corradoi 
although as Bouvier has already indicated this species is very 
similar to 0. eiseni Wheeler described from Tepic, Mexico and 
since reported from Rio Purus in the Amazon basin in Brazil. 
He even suspected that intermediate forms might be found in 
the intervening territory from Mexico to Ecuador. These 
examples fall much closer to corradoi as the nephridial tubercles 
of the fourth and fifth pairs of legs are completely fused with the 
larger portion of the third creeping pad and the smaller part of
