Of the above horns, the best pair (male No. 1) was picked up by me in the 
jungle ; the rest I shot myself. The distance between the tips varies consider- 
ably in different animals. In the case of one small buck which I shot, whose 
horns were about 4 inches long, the tips actually overlapped each other. Not 
only do the dimensions vary in different animals, but there is also a great 
difference in shape. Out of seven pairs of bucks’ horns in my possession, the 
tips of 4 point forwards and of 3 point backwards ; the does’ horns which I 
have also point backwards. 
There is some doubt as to whether Gaczella spehii (or naso) and Gazella 
pelzelni are different species or not. There certainly appeared to me to be some 
difference between the gazelle of the plain near Berbera and those of the high 
plateau to the south ; all the gazelle which I saw on the plateau struck me as 
having a dark stripe of brown, and sometimes almost black, hair along the side. 
I do not remember ever seeing this stripe on the gazelle of the plain near 
Berbera. Both the gazelle of the plain and those of the platean have loose skin 
on the nose, but it is much more marked among the latter than among the 
former. The first gazelle which I shot in Somali Land was about 15 miles from 
Berbera. I looked for the loose pouch of skin on the nose said to be characteris- 
tic of G. naso, and found that the skin was no doubt loose and could be pulled 
up, but this characteristic was so very: slightly defined that I should not have 
noticed it had I not looked for it. In the case of the next gazelle which I 
shot, this time on the plateau, I at once caught sight of the pouch or flabby 
loose skin which les wrinkled up on the top of the nose ; it was most marked. 
I shot altogether 8 gazelles—4 on the plateau and 4 on the Berbera plain, and in 
every case I noticed the above-mentioned differences ; besides the absence of the 
dark stripe on its side, the skin of the gazelle of the maritime plain is, to my 
mind, of distinctly lighter colour and more yellow than is the gazelle of the 
plateau, the latter being much browner. Whether these differences are* suffici- 
ent to justify a division of the animals into 2 different species is a question to be 
decided by more learned naturalists than myself; as far as my experience
