I need data about the geographical distribution, zonation and extension of
the larval phase, as well as data about the type of development of members
of the families Pharidae and Solenidae. In particular, I would appreciate
data on Ensis species (Ensis minor especially) and Solen spp. (Solen
marginatus in particular).

Please do not send me comments based on Poppe & Gto (1993), because I have
those. I also have the classic paper of Urk (1964) as well as Cosel (1993),
but I needed the following reference:

Goud, J., 1984. Amerikaanse zwaardschede, Ensis directus (Conrad, 1843).
Vita Marina: 221-226.

Many thanks for the help,

Sérgio
