144 On Hedgehogs from the Persian Gulf. 
Flab. Mountains north of Aden; type from HI Kubar, 
about 60 miles north of Aden. Alt. 5200!. 
Type. Adult male, B.M. no. 2.11. 22.2. Original num- 
ber 11. Collected 19th June, 1902, by G. W. Bury. 
Whether the facial pattern of this specimen is constant or 
not, the small size of its feet and its whitish head separate it 
from true neger, while the size of its skull distinguishes 
it from P. n. seniculus, which also has a somewhat similar 
general coloration. 
The white Tanb hedgehog, the representative of the large- 
bulla group of Paraechinus, is also a new subspecies of an 
Arabian form. It may be called 
Paraechinus dorsalis albatus, subsp. n. 
Nearly allied, in all essential characters, to true P. dorsalis 
of the Hadramaut, but smaller and more completely white. 
Back at first sight appearing wholly pale sandy, but closer 
examination shows that the spines of the median dorsal area, 
where in dorsalis they are obviously darkened, are here also 
not completely white throughout their lengtk, having a sub- 
terminal brown band. Spines of sides mostly light throughout. 
Muzzle and cheeks brown, with a median brown line running 
up the forehead in some specimens. Lest of head, ears, 
shoulders, and under surface pure white—the inguinal region, 
however, brownish. Hands, feet, and tail also pale brown. 
Skull as in true dorsalis, but rather smaller. Zygomata 
comparatively slender. Bulla of similarly large size, and 
the pterygoids well inflated. Penultimate premolar absent 
in all three skulls, this tooth being minute in some specimens 
of dorsalis and absent in others. 
Dimensions of the type (measured in the flesh) :— 
Head and body 196 mm.; tail 24; hind foot 32; 
ear 44. 
Skull: condylo-basal length 46; zygomatic breadth 27-7; 
palatal length 24°6 ; dental length 22°2 ; length of bulla 10; 
combined length of p* and two anterior molars 11. An old 
male skull measures 48 mm. in condylo-basal length. 
Hab. Tanb Island, mouth of Persian Gulf. 
Type, Adult female. B.M. no, 21.12.3.1. Original 
number 1185. Collected 8th April, 1921, by V. 8S. La Per- 
sonne for the Cox-Cheesman collection. Presented. 
Readily distinguishable from dorsalis by its far paler 
colour. Also related to P. ludlowi, which may prove to be 
best placed as a third subspecies of dorsalis.
