ficent collections of Muscat fishes are known to all ichthyologists, has during 
the past years collected and presented to the National Museum several con- 
signments of mammals from this little-known country. Of these Thomas 
published an account in the ‘ Proceedings’ of the Zoological Society for 1894, 
the most remarkable of them being a new Wild Goat, from the Akhdar 
Range behind Muscat, which was named Hemitragus jayakari after its 
discoverer. In 1897 the British Museum received from Surgeon Jayakar 
another consignment of mammals collected at Muscat within the previous 
two years. In this last series, besides the Oman specimens which were 
referable to species already recorded in Thomas’s paper, there were several 
skins and skulls of the present Gazelle, obtained from the Nejd or Nedsched 
Desert in the interior of Arabia. Thomas established his Gazella marica 
upon these examples. 
In a letter addressed to Thomas, Dr. Jayakar says that four of the “ Reem 
Gazelles” were from the Nejd Desert and one from Dahireh, the north- 
western district of Oman. “It is probable,” he continues, “that the species 
extends down to the desert behind Oman, as that is continuous with the Nejd 
Desert.” Surgeon Jayakar subsequently presented to the Museum a sixth 
(female) specimen from Aboor near Adam in Oman. 
The Marica Gazelle is clearly a close relative of the Persian Gazelle, 
which it seems to represent in Arabia. But it is considerably smaller in 
size, paler in colour, and is nearly free from face-markings, besides having 
horns in the female sex. This last point is interesting, as it shows how little 
importance, in a generic sense, should be attributed to the presence or 
absence of horns in the female of an Antelope; for it appears that this 
species, in which the horns are present in the female, is unquestionably 
more nearly related to one in which the horns are absent in the female than 
to the group of Gazella dorcas, in which the horns are developed in both 
S€XES. 
In February, 1892, the Zoological Society of London received as a gift 
from Lt.-Col. Talbot, then British resident at Muscat, along with a Beatrix 
Antelope (Oryx beatriz), a small female Gazelle, with the information that it 
had been obtained from the Bahrein Islands, in the Persian Gulf. Sclater was 
at first much puzzled to give a name to this Gazelle, but after some hesitation 
came to the conclusion that it might be a small female of the Indian Gazella 
bennetti, which is known to extend along the coast of Baluchistan nearly to 
ang hdl
