THE PERCY SLADEN MEMORIAL EXPEDITION TO GREAT 
NAMAQUALAND, 1912-1913. 
ZOOLOGY. 
By Paul A. Methuen. 
Introduction. 
On the kind invitation of Dr. H. H. W. Pearson, Professor of Botany at 
the South African College, Capetown, to accompany him on a trip to 
Great Namaqualand, I was enabled to investigate the fauna of the Great 
Karas Mountains, a part of German South West Africa which had not 
apparently been previously traversed by scientists. 
I wish here to acknowledge my indebtedness to the Royal Society of 
South Africa for having granted me the sum of £50 towards the cost of 
this expedition and to the Trustees of the Percy Sladen Memorial Funds 
for having defrayed a large portion of the expenses towards the zoological 
investigations carried out.

Great Namaqualand we experienced the greatest kindness on the part of 
the German officials and others who did whatever lay in their power to 
facilitate the expedition. 
Itinerary . Having obtained authority from the late Director and 
the Committee of the Transvaal Museum to undertake the work, I left 
Capetown in company with Dr. Pearson on 23rd November, and 
arrived by boat at Luderitzbucht two days later. Here we stayed a few 
days and then left for our final destination, stopping for a short time at 
Aus (470(1) 27th to 30th November, and at Quibis (4500') 30th November 
to 3rd December en route. We reached Nakeis (4500') on 4th 
December, the farm of Groendoorn (3700') in the Little Karas Mountains 
on the following day, and Wasserfall (4200') which lies at the foot of the 
western slopes of the Great Karas Mountains on 8th December. At 
Wasserfall collecting was carried on chiefly in the sandy plains below the 
mountains. On 23rd December we reached Kraikluft situated in the 
very heart of the mountains at an elevation of about 5200 feet ; we left
