MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 455 



Measurements: No external measurements have been available 

 but the skull of the specimen from Singa, which is unsexed, measures 

 as follows: Condylobasal length 40.9; length of palate 23.6; width of 

 rostrum at level of antorbital foramen 11.4; length of nasals 12.2; 

 least interorbital width 11.8. 



Remarks: The nommate race is darker and, in certain measure- 

 ments of the skull, smaller than A. p. oweni. The outstanding dif- 

 ference in the skulls of these two subspecies is in the width of the 

 postorbital constriction. In A. -p. oweni the constriction is more 

 pronounced and is uniformly so in all specimens seen. 



The specimen from the White Nile, near Khartoum, shows inter- 

 grading characters in color and in the size and shape of the upper 

 molar teeth between A. p. 'pruneri and A. p. lowei. In substance, 

 these characters are more like those m A. p. pruneri, to which the 

 specimen is referred.

Specimens Examined: Sixteen, all in BAI, from: Port Sudan, 4; 

 Shendi, 4; Khartoum, 4; Sennaar, 2; Sinkat, 2. 



Measurements : Measurements of an adult male from Sinkat, Red 

 Sea Province, are as follows: Length of head and body 140; length of 

 tail 20; length of hind foot 26; length of ear 30; condylobasal length 

 of skull 43.2; length of palate 22.5; width of rostrum 9.9; length of 

 nasals 13.9; least postorbital width 10.3; greatest width across zygo- 

 matic arches 26.2. 



Remarks: This genus might easily be mistaken for Atelerix in the 

 field. However, the hairs of the underside of the bod}^ are longer and 

 softer and in general show some blotching of brownish or brownish 

 black in the white. On the head the blackish face mask is present 

 in both genera as well as the white band across the forehead. In all 

 specimens of Paraechinus examined there was always an indication 

 of a blackish band at the beginning of the spines which is not present 

 in Atelerix. In general, the spines of Paraechinus are much softer, 

 thinner, and more densely placed than in Atelerix. There can be no 

 confusion as to identity when the skulls are examined. In Paraechinus 

 the maxillaries do not touch the nasals, and the pterygoid region as 

 well as the auditory region is markedly inflated.
