A couple weeks ago I posted pictures of a dark agouti female I got from a friend, who got her stock in The Netherlands.
Since I breed agouti as my main variety, it's particularly interesting to me as to what makes a mouse so dark. It turns out that is a phenotype of agouti mice called intermediate agouti, which is "in between" full agouti (A/*) and non-agouti (a/a) when umbrous is present, which can present as a thick black stripe down the back of an agouti mouse. With PE dilution, this would present as a dove stripe down the back of an argente mouse (I have a mouse like this).
Here is the preview of the article I found, which describes the phenomenon exactly: http://www.springerlink.com/content/x3l42618rp178607/
I have membership to a university library and have asked them for a full print-out copy of the article.
Edit: found the full article online, though it's poorly scanned (or poorly printed!) here: http://www.ias.ac.in/jarch/jgenet/40/229.pdf
