Nothing is known regarding the habits of this species, beyond the fact that it occurs 
in the Siiakin plain, where it is found wherever there is cover afforded by shrubs. 
It is apparently a more or less desert form, as it occurs on the sterile ground about 
Dongola and in the Bayuda desert. [Messrs. Rothschild and Wollaston found this 
species plentiful in the neighbourhood of Shendi.— W. E. de W.] 
This hedgehog was first described by Ehrenberg from specimens obtained at 
Ambukol (Dongola district). Mr. Matschie has been so good as to allow me to 
examine the type preserved in the Berlin Museum. Whilst there can be no question 
regarding the specific identity of the Suakin hedgehog with this type, it is evident 
that Ehrenberg’s description was based on the specimen after it had been stuffed and 
not on the living animal or on one preserved in alcohol. 
Some years after Ehrenberg’s journey to Dongola, the Upper Nile area was visited 
by Dr. Pruner; some of the hedgehogs collected by the latter traveller came under 
Wagner’s observation and were described by him as E. hracliydactylus, whilst another 
specimen in the same collection and from the same region, but quite young, was 
referred by Wagner to E. cethiopicus, Ehr. A hedgehog identical with this species 
was collected by Mons. M. Botta in Upper Egypt, and is preserved in the Paris 
Museum, where it stands under the name of E. auritus. 
Three specimens from Sennaar are preserved in the British Museum. Heuglin 
obtained at Sennaar a young hedgehog also belonging to this species, which from the 
pale colour of its spines was named by Fitzinger E. pallidus, the type of which I have 
examined. [The locality Sennaar in both these cases seems to be doubtful, as the next 
species {E. alMventris) is the common hedgehog of the White Nile to the south of 
Khartum. But, as in other cases, the locality “ Sennaar ” of the older writers may 
be interpreted “ Upper Nile ” or Sudan.—W. E. db W.] 
There is also a hedgehog in the Berlin Museum collected by Heuglin and said 
to have been obtained by him in Egypt. This is evidently an error, because this
