Cornuta literature?

[JeffG]

Hi All,

Its been a long time since I have last posted, in any case what I really wanted to ask is if anyone perhaps has any refrences to literature dealing with Bitis cornuta? I am doing a "project/assignment" for zoology this semester and have decided to do it on sympatric existence of Bitis caudalis and Bitis cornuta and as such need reference material. I have managed to get a few articles on Bitis caudalis but not so much on Bitis cornuta. Any help will be much appreciated!

Thanks,
Jeff
