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 cryptomerias. 



" The island is well watered. We had frequent heavy rains 

 during our stay, which was from June 28 to July 12. The 

 prevailing tempei-ature at the little interior ha-mlet where we 

 stayed was 74° F. at noon. The nights were slightly cooler." 



Of the geology Mr. Robert Anderson says : " Dogo seems to be 

 fotuided on a formation of very old gneiss of sedimentary oi-igin, 

 which is concealed over much of the surface by recent volcanic 

 i-ocks 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.
