Teledraspis Cope. 



In these Proceedings for December, 1859, I characterized a genus of crotal- 

 ine serpents under the above name. It was intended to include all the 

 serpents hitherto arranged with Bothrops, which possess undivided urosteges. 

 In examining the structure of these serpents, I recognized two sections ofthe 

 genus, the one containing a single species, and characterized by the possession 

 of a series of elevated scales exterior to the superciliary plate ; the other con- 

 taining several species, which have that plate, as is Bothrops, i. e. forming 

 the superior border of the orbit. It seemed probable that these might be 

 genetically distinct, yet the possession of the horned eyebrow by but a single 

 species, would not admit of such a conclusion. Since then, I have received 

 from Dr. Albert Giinther, his description and beautiful figure of Lachesis 

 nitidus, published in the P. Z. S., Nov., 1859. This serpent, which 

 was discovered by Mr. Fraser, in the Andes of Equador, is obviously a second 

 species of the typical group of my Teleuraspis ; we can perceive no propriety 

 in its position in Lachesis, a genus having urosteges anteriorly two-rowed, at 

 the tip four-rowed. 



In the Monatsberichte der Konigl. Preuss. Acad, for March 1859, p. 278. 

 Herr. Peters characterized a genus Bothriechis, for a species resembling a 

 Bothrops, except in its entire urosteges, and keelless scales of the vertex. 

 Excluding the latter character, which does not appear to be of generic value, 

 this genus is exactly co-extensive with my second section of Teleuraspis. 

 The following, therefore, will be what appears to me to be the correct nomen- 

 clature of the species included by me in Teleiiraspis 1. c. with the addition of 

 those here mentioned. 



Crotaline Viperidoz, toithout crepitaculum having a scaled scarlet vertex, super- 

 ciliary plates present, and entire urosteges.
