| Harry, I think that the four specimens below are Ilyanassa obsoleta. They are adults, too large to fit within the camera frame when I use the microscope. On the website I only have juveniles of two species. The average beach walker is unlikely to find juveniles but will see these. They are usually dark brown. The photos from the website are beneath them. | |

Harry, these are Atrina, photographed in the hope of
finding a third species. I had them packed to ship to you. After reading
that you only were interested in small shells, I unpacked them and photographed
them. They are all juveniles, less than five inches tall. I did not
figure out how to photograph them at good angles. I could reshoot, should
you identify a new species. Also, because the flash went off, I rephotographed
some specimens. Hours later I could not tell the first shots from the
later shots.

Atrina 1

Atrina 2. This looks like
Atrina 1 but was more than 1,000 pixels wider.

Atrina 3. Atrina serrata
(G. B. Sowerby I, 1825) Sawtooth Penshell

Atrina 4. Atrina serrata
(G. B. Sowerby I, 1825) Sawtooth Penshell

|
Atrina 5. Atrina serrata
(G. B. Sowerby I, 1825) Sawtooth Penshell
|
|
 |
|
|
Atrina 6. This could be Atrina
1 or Atrina 2. I am sorry for not knowing. It appears to be the same
species. That is all that matters. I can rephotograph later.
|
|
 |
|
|
Atrina 7. I do not know
if this is above. Because it isAtrina serrata (G. B. Sowerby
I, 1825) Sawtooth Penshell, that should not matter.
