and, as I think, offers the best explanation of the facts as at 

 present known. Por I cannot but think that (E. neglecta and 

 (V. jiliilliin are two closely related species, while (E. neglecta, 

 var., is an incipient species which, perhaps, does not always 

 breed quite true. It seems to me that we have in the Kermadec 

 Islands a manufactory of species in full swing, but unfortunately 

 our information is not sufficient to tell us exactly by what process 

 the species are made. 



J). On Vipera renardi, Christoph. By G. A. Boulenger. 



[Eeceived November 25, 1893.] 



(Plate LXIV.) 



When recently describing Vipera ursinii, Bonap.\ I briefly 

 alluded to another European species, V. renardi, described in 

 1S61, but since forgotten or confounded with V. herus. My 

 friend Dr. F. Midler, of Basle, having been so good as to send me 

 specimens from Sarepta, the original locality whence the species 

 was described by Christoph, and the British Museum having 

 received further specimens from the St. Petersbm'g Museum, 

 through the kindness of Dr. Herzenstein, I have no reason to 

 further delay the description of this species, of which I have now 

 17 specimens before me, viz. : — 



1, 2. c? & $ , from Sarepta, received from Dr. F. Midler, one of 

 which he has allowed me to retain for the British Museum. 



3. c? > from Saratov, received from the St. Petersburg Museum. 



4. S , from Ourkatsch, district of Tourgaisk, Kirghiz Steppes, 



I'eceived from M. Nazarow. 



5. S 1 from the River Emba, Kirghiz Steppes, received, as well 



as the following, from the St. Petersburg Museum. 



6. Young, from the Kirghiz Steppes. 



7. S , from Smeinogorsk, Grovernment of Tomsk. 



8-12. Five specimens, J , § , and young, from Chinas, 



Turkestan. 

 13. Youug, from Kunges, Biver Hi, Eastern Turkestan. 

 14, 15. S & 2 1 Wernensky Ujesd, district of Varnoe, Eastern 



Turkestan. 

 16, 17. (S , from Kuldja, Eastern Turkestan. 



^ In the last part of these 'Proceedings,' above, p. .590. Since my note 

 appeared I have received further information respecting that species. First, 

 Mr. A. Erwin Brown lias kindly examined Bonaparte's ty))e specimen in Phila- 

 delphia, and the notes he lias furvvardod me subslaiiliate my C(jnc]iision8. 

 Secondly, I have been able to extend tlie known range of this Viper to France, 

 having received a specimen from tiie Basaes-Alpcs, through M. ll(jnnuraL, on 

 which I have reported in the ' Feuille dea Jeuues Naluralistes,' xxiv. 1893, 

 p. 8. And lastly, I am informed by Prof. O. Boettger and Dr. F. Werner that 

 they have received specimens from the mountains of Bosnia, which agree iu 

 all essential respects with those from Laxenburg.
