MOUNT MARIVELES 
December 26, 1920, to January 1, 1921. I collected on the northern side 
of Mount Mariveles. Two specimens of the rare Hologerrhum philippinum 
were taken, but nothing else that was noteworthy. 
MOUNT MAQUILING 
April 15 to June 1. During this period extensive collections were made 
on Mount Maquiling. A specimen of Oxyrhabdium, which is distinct from 
the two recognized forms, was taken, but it escaped from a faulty col- 
lecting bag. 
Aside from collections made by myself I have obtained small collections 
from southern Leyte, Sibuyan, Romblon, Batan Island, Busuanga, and 
Balabac.
