Mr. Eaton records that his specimen from Alger (which 
is ticketed as a 2 but is certainly a ¢) was taken along 
with another ‘‘ burrowing in sand.” There must be some 
mistake, however, here, I think; for the other specimen, 
though superficially very like this, is a g Diodontus ; and, 
normally at least, Passaloccus nidificates in wood (posts, 
palings, etc.) and not, ike Diodontus, in sand.

The specimens are mostly rather small. Some of my 
own have been determined by Herr Kohl as shuckardi, 
and I think they all belong pretty certainly to that species.
