162 The Philippine Journal of Science 1922 
April 19 and 20. I collected in the vicinity of Bontoc and was dis- 
appointed because of the few specimens found. Doctor Schofield saw a 
turtle in the market, but it had disappeared before I could get it. 
April 21. I left Doctor Schofield at Bontoc and set out for Balbalan, 
Kalinga. 
April 23. Near Balbalan I found a specimen of Hologerrhum philip- 
pinum. I purchased a specimen of the mammal Phloeomys pallidus. 
April 23. Near Balbalan I found a specimen of Hologerrhum philip- 
and as a result amphibians began to breed. I collected large series 
of several species, some of which are new. 
May 2 and 8. Balbalan to Bontoec. Very few specimens were collected. 
May 5. I climbed Polis Mountain. 
May 6. I arrived at Banaue. 
May 7. Banaue to Kiangan. Amphibians were heard at night near 
Kiangan, but I was unable to collect any of them. Two young specimens 
of Elaphe erythrura were collected along the trail. 
May 8. Kiangan to Nayon. 
May 9 to 12. I collected Kaloula picta and several of the commoner 
lizards in this vicinity. . 
May 13. Nayon to Kiangan. 
May 14. Kiangan to Tauang. 
May 15. Tauang to Manhuyhuy. A small frog, probably Cornufer 
meyeri, was found dead near the trail. 
May 16. Manhuyhuy to camp 59. Between kilometers 65 and 64 a 
large red frog jumped into the trail in front of me and from there into 
the cafion. This frog appeared to be an unknown species of Rana. The 
elevation at this place is about 2,500 meters. No frog has been recorded 
from so high an elevation in the Philippines. 
May 17. Camp 59 to Baguio. 
MANILA AND VICINITY 
During May and June, 1920, I made numerous trips about Manila, to 
Mount Maquiling, and to Mount Banahao,

POLILLO AND CALOTCOT ISLANDS 
July 8. I left Manila by rail for Hondagua where I took the steamer 
for Polillo. ; 
July 9. I arrived at Polillo. 
July 10 to 23. In the vicinity of the town of Polillo, I collected numerous 
specimens. 
July 24. I went to Burdeos on the east coast of the island. A snake, 
probably a species of Natrix, was seen on the trail, but I was unable to 
capture it. 
July 25 to 27. Some interesting specimens, including Rana merrilli sp. 
nov. and Typhlops cumingii (Gray), were collected near Burdeos. 
July 27. I embarked in a small banca for Calotcot Island, which is 
about 25 kilometers east of Polillo. 
July 28 to August 1. Calotcot Island is about 3 kilometers long and 
is heavily forested. There is a small clearing at the southern end. Eleven 
species of lizards and three species of snakes were taken on this island. 
No amphibians were seen. I returned to Burdeos during the night of 
August 1.
