P 716. Operculina ammonea, Leym. In black limestone. “ Yal d’lllier, 
Yaud. P. M. Renevier.” From the Museum of Practical Geology. 
There is much doubt as to these specimens. Prof. E. Renevier, having been 
asked about them, kindly replied thus : — 
“ Lausanne, 15th November, 1881. 
il Dear Sir, — I have no remembrance whatever, nor has Dr. De la Harpe, of 
the two specimens you write about. I doubt that they came from me. 
“ Val d’lllier is in Bcis- Valais , running from Mouthey (famous Moraine) to 
Savoy (not in Yaud). There are all kinds of Terrains ; Eocene = Nummulitic 
forms a band all along on the foot of the Chain of Dent du Midi, in beds gene- 
rally reversed, and covered by Gault and Neocomian ! There is no N. Peri- 
bland ! Periblanc is a locality in Alpes Yaudoises, where only N. striata is 
found. In Val d’lllier, De la Harpe has ascertained five species of Nummu- 
lites — N. Ruetimeyeri, Chavanessi *, Bouchen *, Fichteli, and intermedia. 
“ Ever yours, 
“ E. Renevier, Prof.”

A. exponens. Smooth and much flattened. With small Num-
