On the Reptiles and Batrachians of Amoorland. 137 



XVII. — A List of the Reptiles and Batrachians of Amoorland. 

 By G. A. BOULENGER. 



[Plate IX.] 



The recent acquisition by the Trustees of the British 

 Museum, among other examples from the late Dr. J. G. 

 Fischer's collection, of a series of Reptiles and Batrachians 

 obtained by Hr. Domes of Hamburg on the Ussuri River *, 

 has induced me to publish, in addition to notes on the little- 

 known forms, a complete list of the Reptiles and Batrachians 

 hitherto recorded from Amoorland. This fauna presents an 

 interesting mingling of North Palaearctic (Lacerta vivipara, 

 Viper a berus, Rana temporaria) , Central Asian (Eremias), 

 Japanese {Tropidonotus vibakari), and Oriental {Tachy- 

 dromus. Coluber tceniurus) types.

Described by Peters from examples obtained at Kasake- 

 wicha, on the Amoor. The following description is taken 

 from four specimens (2^,2 ? ) collected at Chabarowka by 

 Hr. Domes. 



Snout short, obtuse, its length equal to the distance be- 

 tween the orbit and the posterior border of the tympanum. 

 Granules between the supraoculars and the supraciliaries 

 absent or reduced to two or three ; a small shield, sometimes 

 broken up into two or three, separates the large anterior 

 supraocular from the loreal ; temporal scales perfectly smooth, 

 7 or 8 on a line between the orbit and the tympanum ; four 

 (rarely five) upper labials anterior to the subocular ; three 

 specimens have four pairs of chin-shields, the fourth has five. 

 Large dorsal scales in 7 or 8 longitudinal series, of which 

 the median are smaller than the others ; 24 to 27 in a longi- 

 tudinal series between the axils. Ventral shields smooth, 

 outer very feebly keeled, in 8 or 10 longitudinal and 25 to 

 28 transverse series. Prasanal shield entire in the males, 

 divided or semidivided in the females. Three inguinal pores 

 on each side. Brown or olive above, uniform or with darker 



* I bad previously described a new genus of Newts, Geomolge Fis- 

 cheri, from the same collection (P. Z. S. 1886, p. 416).
