Type. 
Lithocranius*, Kohl, Ann. Mus. Wien,1i. p. 79 (1886) . . . . . UL. WALert. 
Size about as in the larger Gazelles. Form very peculiar, owing to the 
great elongation of the neck, which gives almost a Giraffe-like appearance 
to the animal. Limbs also very long; false hoofs quite minute. Colouring 
of the head less typically Gazelline than in Ammodorcas, but a modification 
of the light lateral body-line present. 
Skull (see fig. 85, p. 231) excessively long and low, the cranial part 
behind the horns particularly lengthened ; the bones of this part very solid 
and stony. Bulle low and opaque. A shallow anteorbital fossa present. 
Premaxille not reaching the nasals. Lower jaw slender and delicate. 
3 : 
Premolars 5, the anterior one above almost as large as the second. 
Horns thick, oval in section, very closely ringed, curved backwards as in 
many species of Gazella for the greater part of their length, their middle 
portion more or less lyrate, as in Gazella dorcas, their tips recurved upwards 
or forwards. Female hornless. 
Range of the Genus. Somaliland and British Kast Africa. 
One species only. 
* Misprinted Litocranius in the original description. The name is based on the solid stony 
character, of the cranium (Aifos = lapis).
