Corrections (to Coded classification of Squamatiformes)

[Ken Kinman]

Dear All,
       I've already found a couple of small errors in my classification.  First, the snake family Cylindrophiidae is marked as extinct (which it isn't).  And secondly, the lacertilian family Helodermatidae is coded as being a clade (8) spltting off separately from the Lanthanotidae-Varanidae clade (9).  However, all three share a compound mandibular venom gland (which presumably only evolved once), so they should probably split off together as one single clade:

  8  Helodermatidae
  B  Lanthanotidae
  C  Varanidae

      I am also very tempted to place the related family Necrosauridae in this clade as well, but since it is extinct (thus based on fossils only), I want to study that more carefully first.

       ----Cheers,
                Ken Kinman
