"Within the limits of the Eussian Ejupire, this Hedgehog is very 

 common in the Transcaspian province, where it takes the place of 

 the foregoing species. The specimens from this locality agree 

 perfectly with the excellent description and drawing in Blanford's 

 work. This species will probably also be found to inhabit the 

 southern parts of Eussian Turkestan. 



4. Ekinaceus oalligoki Satunin. 



Known for the present only from the sandy district along the 

 foot of Mount Ararat, near the village of Aralyk, about 40 versts 

 to the south of Erivan. 



It is possible that the long-eared Hedgehog of Mesopotamia 

 belongs to this species, as the true E. auritus can certainly not 

 exist there. 



B. The pterygoid foss® almost disappearing, the pterygoids being 

 enlarged and bullate, the cavity contributing to the enlarge- 

 ment of the auditory chamber. On the top of the head a 

 well-marked bare space, covered by folds of the skin. 



' 5. EaiNACEUS MACE ACANTHUS Blanford. 



Erinaceus macracanthus, Blanford, Ann. Nat. Hist. (4) xvi. 

 p. 310 (1875); Blanford, East. Persia, ii. p. 27, pi. i. (1879); 

 Dobson, Monogr. Insectivora, pt. i. p. 15 (1888); Zaroudnoi, 

 Eech. Zool. Contr. Transcaspienne, separ. p. 34 (1889-90). 



Erinaceus ambitus (partim !), Eadde & Walter, Zool. Jahrb., Syst. 

 iv. p. 1006, albino (1888). 



Obviously not scarce in the South-eastern part of Transcaspia, 

 whence I have received several specimens. More commonly met 

 with in the neighbourhood of Askhabad. 



The dark colouring, as given by Blanford, I find only in young 

 animals. With age the colouring gets lighter, and in old speci- 

 mens it becomes of a uniform yellowish-white.
