In his report on the fresh-water copepoda from Panama 
Marsh 1 states that the general character of the copepod fauna 
of the Canal Zone is much more closely related to the South 
American fauna than to that of North America. This, how¬ 
ever, does not appear to be true of the copepod fauna of Guate¬ 
mala and Salvador since it consists chiefly of North American 
forms. Among the Calanidae only one form, Diaptomus marshi , 
is so far known to be common to the fauna of Panama and that 
of Guatemala and Salvador. 
I am greatly indebted to Mr. H. K. ITarring for the identifi¬ 
cation of the various rotifers.
