NoMENCLATURE NOTE ON THE MALLOPHAGAN GENUS ANCIS- 
TROCEPHALUS PAINE.! 
The fact has recently come to the notice of the writer that the 
name Ancistrocephalus, recently employed by him for a new genus 
of Mallophaga, is preoccupied, having been used by Monticelli 
for a genus of Cestode worms in about 1890; this name, therefore, 
cannot be used for the Mallophagan and is herewith substituted 
by the name Physconella. The type of this genus is Physconella 
kelloggi Paine, as described in the paper referred to in the accom- 
panying footnote.
