“MAMMALS COLLECTED IN SIAM. 335 
roadless bush. Outside the wheels of these carts two slightly 
curved stringers extend from back to front and, where the ruts of 
the track are too deep for the wheels to touch bottom, the “kwien” 
in able to proceed for short distances on these runners; they also 
keep it from tipping over. 
From Korat we went back westward about thirty miles to 
Lat Bua Kao. From the village gently rising forested hills, which 
I had planned to visit, were visible to the south; but heavy rain, 
followed by a 25-foot rise of a river between, and the washing away 
of the only bridge, put an end to hopes in that direction, and we 
had to be content with working the country to the north of the 
village. This consisted of scrub and bamboo and a few patches of 
very poor dense forest which harboured scarcely any vertebrates. 
After a fortnight, interest in this locality began to diminish and we 
returned to Bangkok. Wild cattle (probably Bos bantenq), serow and 
deer occur near Lat Bua Kao, but none were met with. 
Next I went to Srirvacha, on the west coast of the Inner Gulf 
and, hiring a mat-sailed “rua-pet” about 35 feet long, visited the 
islands to the south (Koh Lan, Koh Kram) as far as Koh Mesan, 
off Cape Liant, and spent two or three days ashore at the village of 
Satahip in Shelter Bay, before returning to Bangkok again after 
ten days’ absence. The fauna of the little islands was, of course, 
very poor, but some interesting races of mammals were obtained. 
The next collecting place was the village of Pak Bu, in the 
rice-fields near the mouth of the Tachin River, or Nam Supan, 
about twenty miles west of Bangkok; only three or four days were 
spent in this locality as it was soon exhausted. 
The final excursion was a ten days’ visit to Koh Lak, situa- 
ted on the west coast of the Gulf of Siam in about Lat. 11°50’ N.; 
again floods cut us off from the forest and the hills, and confined us 
to the open country near the shore. 
Thus the collections made largely illustrate the more or less 
open country of Siam, and provide in some ways an interesting con- 
trast to the results of my former visit, which were obtained in the 
forested country to the south-east (P.Z.S, 1916, pp. 27—75).
