This agrees in general with the accounts of H'lppocanipiiH kuda 
Bleeker, from the East Indies (wrongly called 11. (/uttulatw^)., but that 
species has ll+'^3 rings, and typical specimens difl'er greatly in color 
from our specimens. The original account of JI. iiichu}<)><plJvs by 
Bleeker diti'ers equallv- We may therefore provisionally regard our 
examples as distinct.
