Next in order southward is a gap more than ioo miles wide of 
drier, open savannah woodland (Fig. 5) in which may be an isolated 
piece of rain forest near the head of the Jardine River, unknown 
biologically (Brass 1953, pp. I 54 > 161). 
Next is the mid-peninsular rain forest system. It extends irregularly 
and with perhaps slight interruptions from near Iron Range and Mt. 
Tozer south to the “Rocky Scrub” east of Coen. Altitudinally it ex- 
tends from near sea level ( e.g . at Iron Range) to about 2,000 ft. on 
the higher summits of the Mcllwraith Range. It includes fairly heavy 
rain forest, although its quality varies locally.

peninsula. (P. J. D. 1932). Such woodland is an effective barrier to rain 
forest Carabidae in the tropics. 
Next, after another gap more than 150 miles wide of drier, open 
woodland, is the base-of-peninsular or main tropical rain forest system 
of North Queensland. Outlying pieces of semi-rain forest of this 
system are within sight of Cooktown, and heavier rain forest begins on 
the coastal mountains (Mt. Amos, Mt. Finnigan) about 20 miles to
