It is a Soundscriber Disc and will play back with a microgroove stylus.
I have worked with many of them over the years.

Dear Barbara Need,
If the disc is translucent green vinyl, it may be a Soundscriber
disc.
These were 33.3 rpm microgroove, so you should try to play it as if
it
were an LP. Pray that it hasn't warped; if it has, you may need to
send
it to someone with excellent equipment and much experience.
Sincerely, Richard

I have been asked to get a digital transfer from what I believe to
be
a "Flexi disc" (thin green plastic /vinyl disc with a square hole).
The only complication is that, as far as I can tell, these were LPs
and, therefore, no earlier than 1948. The date on the disc, however,
is '43. We have an osmium stylus (which we use for 78s) and a
diamond
stylus (which we use for LPs). What stylus should I use for
playback?
(And if you have recommendations for adding to my stylus supply, I
would welcome that as well, though I may not be able to do anything
about it just yet.)

I've seen very thin flexible orange and yellow discs which were used
for home
disc recorders in the 40s..don't know why this one would have a square
hole,
unless the original hole was too tight and someone has enlarged it. If
it's one
of these home cuts, it would probably play at 78. Does it look like a
factory
product with a printed "label" or might it be a home cut?
