This specimen is in the white-breasted phase of plumage, having the whole 
of the under surface of the body white, as also the throat, which has, 
however, a very few narrow streaks on the lower part and somewhat 
broader marks on the sides. The following notes are recorded of the bird 
in the flesh : length 470, wing 382, tail 195 ; cere and feet yellow. 
Lophoceros nasutus maraisi, subsp. nov. 
Similar in colour and general appearance to L. nasutus, but smaller 
in size in all respects : male (type), wing 202, tail 180, tarsus 35, 
culmen 80 ; female (cotype), wing 187, tail 175, tarsus 31, culmen 68. 
Three forms of this species are recognized by Reichenow in his 
“ Vogel Afrikas,” namely, L. nasutus, (L.), L. n. forskali, (Hemp. Ehr.), 
and L. n. epirhinus, (Sund.). Of these, the first seems to be widely dis- 
persed over North-West Africa and North-East Africa as far south as the 
Pangani River in German East Africa ; the second occurs in North-East 
Africa only ; and the third in South Africa (both on the west and east), 
its range apparently extending to German East Africa. From this it seems 
that there is a certain amount of overlapping of forskali and nasutus in 
North-East Africa and epirhinus and nasutus in German East Africa ; but 
whether this is really so or merely the result of hasty identification can 
only be ascertained by more careful research. L. forskali differs from 
nasutus in having a longer wing, and epirhinus from nasutus in the casque 
being produced farther forward with a more pointed tip. The fourth form 
which I have here described is like nasutus in the shape of the casque, but 
in size is so very much smaller in all respects that I have no hesitation in 
describing it as new. Both the type and cotype are fully adult, and seem 
to have been a pair. The following figures (the lesser of which in each 
cas^e are referable to females) are taken from “ Die Vogel Afrikas ” and 
the type and cotype of maraisi : — 
Wing. Tail. Culmen. 
L. n: nasutus 200-225 200-220 75-97 
L. n. epirhinus 200-230 190-215 75-100 
L. n. forskali 220-240 215-235 90-113 
L. n. maraisi 187-202 175-180 68-80 
The type and cotype of this new form are from the collection of the 
late J. v. 0. Marais, but the labels bear no indication of the locality except 
“ Rhodesia,” and, as all the specimens he collected in East Africa on his 
ill-fated expedition were so labelled, that cannot be accepted as a guide. 
His note-book is in the Museum, however, and in it a pair of hornbills, 
with remarks on the colour of the bill in the two sexes, is recorded on the 
29th June ; no precise locality is given about that time, but he seems to 
have left Bagamojo on the 25th June, and after four days’ marching he 
seems to have settled down to collect specimens, although he suffered con- 
siderably from recurring attacks of malarial fever. His notes on the two 
specimens agree exactly with the two now in the Museum, and as only 
two others of the family have been recorded in his diary and are obviously 
referable to L. deckeni in his notes, I do not think there can be any doubt 
as to the locality in which they were taken.
