Show 358 MR. OLDFIELD THOMAS ON [Nov. 28, mountainous island, rising in places to over 2000 feet. Only tlie broadest valleys are cultivated, and tlie 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 cryptomerias. " 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 rocks 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. 1.
