 Mast cells are very numerous in the habenula (and also in the dorsal
 parts of the thalamus) of the hedgehog (Erinaceus europeus) and the
 tree-shrew (Tupaia glis). In many other kinds of mammal they are
 absent from this region. In the hedgehog, EM shows that some of the 
 MC are truly in the neuropil. I can send or post references if anyone's
 interested.
