Cote II 88, Bon 106, BvH 4/12, BvH ill II #185. Perhaps at Ville-neuve canal jetty. I am smaller than in spec desc or preceding page no proof whether the 2 groups of apex are the same sep. or not.

Deors distinct and deep all around but edges not as thin, nor as divergent as assumed frondesc. nor as ill (BvH ill II #185) [#187, not in SUTI, is better for cross section] the edges in #187 are not quite sharp enough! Styles about as long as fr. is high.
