1, C. Bouquete, Montr. Specimen not seen. Neither the 
genus nor the species is determinable from the description. 
2. C. incurva, DC. is not a Canavalia. The name is founded 
on Dolichos incurvus, Thunb., which the author identified with 
Japanese Nata mame. That name means “sword bean” and 
has been given by some Japanese authors as equivalent to the 
Sword Bean, Canavalia gladiata. But Thunberg’s description 
shows his plant to be different in many respects from that species 
and even from the genus. It seems probable therefore that 
Thunberg connected the plant he was describing with Nata mame 
wrongly. 
3. C. macrobotrys, Merr., C. megalantha, Merr. and C. tortilis 
Frapp. We have seen. no specimens and the species cannot 
from the descriptions be placed in the Key. 
XXII.—A SHORT TRIP ON MT. ELGON, UGANDA. 
C. H. LANKESTER, 
In August last year, at the conclusion of a visit to inspect 
the Native Coffee Cultivations of the Bagisu, on the western 
slopes of Mt. Elgon, I had the good fortune to meet there, on 
Safari, the District Commissioner on tour, and proximity to the 
nearest route up the mountain suggested a hurried trip to the 
Jackson Summit. This was planned and duly carried out, 
four days being taken in all, including the return to Mbale. 
The folds and valleys of the Elgon foothills where these 
meet the Bukedi plain are very densely populated, the lowest 
hills especially are almost covered by banana “shambas ” of 
the native Bagisu, who differ very widely from the type of 
negro inhabiting the Kingdom of Buganda, with whom I had 
had a short introductory acquaintance. 
The Bagisu are of smaller stature and are. a much more 
primitive people, approximating to the Congo Pigmy group. 
The men wear heavy neck-collars of iron and frequently anklets 
of the same, the women, scanty costumes, either of fresh banana
