rifles, and I was obliged to take out my little army twice against 

 villagers ; but luckily no blood was shed, as the villagers, seeing the 

 rides coming, immediately restored my stolen property. I did no 

 collecting to speak of here, as 1 was ill with fever and was having 

 a very anxious time. I could get no guide to take me across the 

 great waterless desert of the Mareban, and was obliged to load up 

 the water-vessels at DoosaMoreb and start without one. I believe 

 I was the first white man to visit the heart of the Marehan and 

 Haweea Countries, and was right glad to shake off the dust from 

 my feet on quitting those inhospitable tribes. How I lost my 

 way crossing the Marehan Desert, ran short of water, and all but 

 died of thirst, I have already described in the pages of the ' Wide 

 World Magazine.' We reached Galadi in the Mijertain Country, 

 and found water in the very nick of time, when I was almost at 

 the last gasp. Here I became delirious, and knew nothing that 

 was going oo around me for hours. After leaving Galadi I became 

 so ill and weak with fever that I did no further collecting, but was 

 practically carried by my pony the whole way across the waterless 

 Hand again to the Grulis Range, where I remained a few days to 

 rest, and at length reached Berbera more dead than alive. 



A full account of my two expeditions, together with a complete 

 every mammal ami bird known to inhabit the country, will 

 be found in my book : Somaliland,' published in 1899 by Messrs. 

 P. E. .Robinson & Co., London. 



The specimens mentioned ami described in the following pages 

 are in the Hope Collection, University Museum, Oxford, with the 

 exception of those which are expressly stated to be in the British 

 Museum.
