﻿Herpetological Notes. 291 



8. Aepyurus for Aipysurus and Platyurus for Platurus. 



I cali attention to the fact that Aipysurus amó. Platurus are 

 incorrectly spelled and that Agassiz has already made the 

 correction (1846), writing Aepyurus and Platyurus. 



9. Merremia for Sepedón. 



The ñame Sepedón having been employed for a genus of 

 Díptera by Latreille in the year 1804, Merrem's Sepedón, a 

 gemís of snakes (1820), must be changed. I propose Merre- 

 mia, and it's species is now Merremia liaemachates (Lac). 



10. Cochliophagus for Leptognathus. 



Leptognathus adopted by Duméril and Bibron in the year 

 1853 and admitted also by Boulenger in his excellent «Cata- 

 logue of the Snakes in the British Museum» (1896) cannot 

 be used for this genus, as the ñame was already preoccupied 

 by Swainson (1839) for a genus of Fishes, and by Westwood 

 (1841) for a genus of Coleóptera. 



As amongst the several synonyma of this genus, enume- 

 rated by Boulenger, the oldest is Cochliophagus Duméril & 

 Bibron (1853), this ñame must stand for Leptognathus. 



The argentine species of this genus are : 



1. Cochliophagus Catesbyi (Sentz.). 



2. » Mikani (Schl.). 



3. » turgidus (Cope). 



4. » ventrimaculatus (Blgr. ), sea Jul. Kos- 

 lowsky (Rev. Mus. La Plata, vin, p. 198. — 1898).
