: Wolfgang,

: I finally had time to read in entirety these comments, and as usual I have a question.

: Please define the following:

: A level that exceeds intrageneric divergences?

Basically, if you look at most currently recognised snake genera, and you compare mtDNA sequences (in my case ND4 or cytochrome b) between the most different species, of a genus, you most often get levels of divergence of around 15%. This also applies within what is currently called Pseudechis, except for P. porphyriacus: P. porphyriacus differs from other Pseudechis by 17-20%, so it clearly is a long-separated lineage.

: In addition, I tried to print out the contents of the text at the office ,(came out so light, very difficult to read), and at home ,(printed out the picture of Pseudechis cf. australis, the parsimonous tree, and absolutely no text whatsoever?). I saved the text to file, however, I like hard copy backup if at all possible. Be advise, I am not complaining, just thought I would bring this matter to your attention.

Pass - try saving it and changing the colour scheme in Netscape Composer and then printing it out. I have not installed any "anti-printing devices"!

: Cheers,

Cheers to you too! ;-)
