Tupinambis duséni Lönnberg. 



Dr. P. DrsEN has sent home a Tupinambis from Paranå, 

 which is very different from the three hitherto known species 

 of this genus, and ^vhieh I therefore take the pleasure of de- 

 scribing and naming af ter the collector. It has two loreal 

 plates and oval dorsal scales, and is by these characteristics 

 distinguished from T. nigropunctatus . The dorsal scales are 

 convex, and the transverse series of scales across the belly 

 count about 46 in number. In this respect it approaches 

 nearer to T. rujescens than to T. teguixin. The specimen from 

 Paranå cannot, however, be referred to the former of these 

 two species as T. rujescens is said to have »all the scales con- 

 siderably smaller», a fact well proved by Gunther's figure, 

 than those of T. teguixin, while the new species has compara- 

 tively mueh larger scales even than T. teguixin. In its gene- 

 ral shape it appears to resemble T. rujescens more than T.
