called Gharabwein, within a day's march of Obbia in the 

 Mijertain country, Italian Somaliland. They were inhabiting 

 thick aloe scrub country, and were plentiful in a locality some 

 little distance from water ; they were very local and appeared to 

 be surrounded by M. phillijjsi. 



The following are the measurements in the flesh of the type 

 specimen — a male in the British Museum, No. 356. 



Head and body 475 mm. 



Tail 37 „ 



Hind foot 137 „ 



Ear 62 „ 



Weight 4ilbs. 



Skull-measurements. 



Total length 92 mm, 



Basal length 80 „ 



Posterior edge of orbit to gnathion 65 „ 



Upper cheek-teeth 32 „ 



Length of nasals 16 ,, 



Breadth of nasals 8"5 „ 



In comparing the above skull-measurements with a typical 

 M. sioaynei, it will be found that they are jjractically identical. 



This bright and beautiful Dik-dik I propose to name in honour 

 of my friend Mr. Piacentini, the Acting Consul-General for Italy 

 in Aden, through whose kindness and help I was able to send my 

 collector to the Mijertain country.

This Dik-dik, known to the Ogaden Somalis by the name 

 ^' Ghussleh" or " Gussuleh," owing to its habit, when startled, of 

 dashing off in leaps and bounds, giving vent to a peculiar 

 whistling cry which sounds like " Ghuss-Ghuss-Ghuss," is chiefly 

 found in Western and West Central Somaliland. Swayne tells us 

 that he first met with it when travelling in a south-westerly 

 ■direction in the Her Amaden country, i. e., roughly speaking, 

 between the 7th and 8th parallels of north latitude ; this is its 

 northerly limit, as Mr. J. H. Dodds tells me that during a recent 

 journey he made in Western Somaliland he never met this Dik-dik 

 until he got to Daggahbur, a well-known Ogaden watering-place 

 near Milmil. 



Starting from Daggahbur in the north this Dik-dik passes in a 

 southerly and south-westerly direction for Dolo at the junction of 

 the Dawa and Ganale rivers, and then crossing the Juba is 

 ubiquitous throughout north-eastern British East Africa. I do 

 not think it reaches the coast anywhere, being there replaced by 

 R. kirkii. In Somaliland proper its easterly and south-easterly 

 limits are still unknown. 



It probably extends for a considerable way down the Webi
