358 MR. OLDFIELD THOMAS ON [ Nov. 28, 
mountainous island, rising in places to over 2000 feet. Only the 
broadest valleys are cultivated, and the hill-sides near the sea. 
The mountains are steep, but not usually rocky. With few 
exceptions dense forest clothes all the mountain-sides and tops. 
It consists of oaks, elms (‘zelkova’), chestnuts, camelias, pines, 
firs, and eryptomerias. 
“The island is well watered. We had frequent heavy rains 
during our stay, which was from June 28 to July 12. The 
prevailing temperature at the little interior hamlet where we 
stayed was 74° F. at noon. The nights were slightly cooler.” 
Of the geology Mr. Robert Anderson says: ‘‘ Dogo seems to be 
founded on a formation of very old gneiss of sedimentary origin, 
which is concealed over much of the surface by recent volcanic 
vocks and local Tertiary deposits.” 
31 specimens were obtained in Dogo, belonging to the following 
six species. Several show some slight modification as compared 
with their Hondo allies.

These specimens are in no way distinguishable from the large 
Mole of 8.W. Hondo. 
Their skulls, without exception, are all within the narrow 
limits of 38 to 40 mm. in total length.
