By the kind intermediation of Dr. Hartert, tlie British 

 lyiiiseum has received, as a donation, from Mons. Bhxnc, the 

 well-known natnralist of Tunis, a number of small mammals 

 from that still little-known country. 



Among these there are examples of the following new 

 form of hedgehog : — 



Paraechinus deserti blancalis, subsp. n. 



Essential characters as in true deserti\ but wiih a greater 

 amount of white. Under surface almost wholly white, a 

 small area in the inguinal region alone brown ; in deserti the 

 lower surface is prominently brown as far forward as the 

 sternum. Ears whitish behind, with scarcely any brown on 

 them. Limbs also with less white, the terminal brown only 

 commencing on the wrists and ankles, while in deserti the 

 forearms and legs are also brown. 



Skull as in deserti. 



Cundylo-basal length of skull 46 mm. ; zygomatic breadth 

 28 ; upper tooth-series 21"7. 



JIab. Island of Djerba, S.E. Tunis. 



jli/jje. Adult female. B.M. no. 20. 5. 4. 5. Original num-

 mens examined. 



No doubt very closely allied to the deserti of the mainland, 

 bu; distinguishable by its less brown underside.

Remains of Theropodous Dinosaurs in deposits of Liassic age 

 are of extreme rarity. Lvdekker has described and figured 

 (Catal. Foss. Kept. Brit. Mns. pt. i. (1888) p. 173, tig. 28) 

 a tooth from the Lower Lias of Lyme fiegis, which lie 

 doubtfully refers to the Triassic genus Zanclodon. Later, 

 Dr. Smith AVoodward gave an account with a figure (Ann. 

 & Mag. Nat. Hist. ser. 8, vol. i. (1908) p. 257) of a small 

 slender right tibia irom the Lower Lias of Wilaicote, 

 Warwickshire. This he regards as belonging to a lightly-
