Which Spider? - Arctosa littoralis

Which Spider? - Arctosa littoralis
Eastern Neck NWR, Queen Anne's County, Maryland, USA
June 5, 2009
Size: Around 1"
This white arachnid was found along the beach of the Chesapeake Bay.
I'm thinking some sort of wolf or fishing spider but I've never seen one this color before.

Arctosa sp.
Arctosa sp. (Lycosidae) looks like a possibility. See for comparison:

Thanks!
It looks like Arctosa littoralis is what I'd found on that sandy beach.
It was truly blessed with incredible camoflage.

Dondale & Redner's (1983) key
Dondale & Redner's (1983) key gives the following characteristics for littoralis: "Femur I with two prolateral macrosetae near tip . Tibia III with three retrolateral macrosetae. Legs usually with dark rings."

I definitely can see the two prolateral macrosetae on femur I. The distribution appears to be widespread across central North America.

The article is available online via the AAS, but suddenly Google is failing me.
