The last issue of Lethaia (30:1) has the latest article on the
calcichordate, in which Jefferies replies to criticism by Peterson (1995).
Other references can be found there. Of course, the central reference to
Jefferies' theories is his 1986 book, "The Ancestry of the Vertabrates",
published by the (then) British Museum (Natural History).
