d'Orbigny (p 92) says 4 following genera are found in no part of West coast. (how far does he include?) Mr Cuming found, however, these as follows.

Bulla Callao & Payta

Cardium Payta Tunberg 3˚40' St Elena 2˚10' S

Perna (Xixappa) West Columbia 1˚23' S.

Mya ─ (nowhere)

do (p. 90) says following 6 genera, not found in

[108v]

(which in south Tunberg or Payta?)

Hence in tertiary period many genera elevated further southward there now.─

{Cuming quite bears out with Mr Hind statement about difference of shells on two coasts.

(Tasillaria at Arica)

[108a]

Mr Cuming thinks that the Mytilus (striated) magellanicus is different on Valparaiso coast, from what it is in Chile.

The mesodesma donaciforma is same as Erycina donaciforma; former correct name: it lives just at level at lowest tides; so is just to be uncovered

[108av]

Compared my Patagonian & Chonos & Chiloe shells & not one in common = The voluta ancilla from S. Crus rounded & therefore perhaps drifted)

The Mytilus from Lima & Chile is very different from the M. Magellanicus of T. del Fuego ─ Patagonia

Coquimbo Pecten (recent) thought by Cuming wrong locality. H Compare fossils H ─ (not identical & probably quite wrong locality)
