This type has occurred only in sites which have Alto Focus pottery; it
has not been found in Bossier Focus sites which lack established Alto
types. In the Bossier Focus, the related engraved type seems to be
_Maddox Engraved_, which in northwestern Louisiana has cross-hatched
engraved bands, generally not curving and most often vertical, as the
major element. In central Louisiana _Maddox Engraved_ type has been
extended to include curvilinear bands of cross-hatched engraving (Suhm
and Jelks, 1962: Pl. 50). The decoration on Plate 50, _F_ of this
handbook is very much like _Carmel Engraved_ and this vessel probably
should be included in this type instead of _Maddox_.
