(OP)
(see attached photo)
Looks like about a six foot long precast curb with holes hollowed out of the middle to reduce weight. Then they have a bell end so you can fit one in the other. No sort of tieback, and no way to connect an upper course of them to a lower one in a retaining wall. This wall was built in the early 80s, by stacking these things on top of each other and backfilling.
Any idea what these things are called?

Any chance those holes are intended for post-tensioning?

The photo I linked was probably the worst looking spot in the area, but none of it looked great. It also abutted a creek, so there's some undermining in places due to scour. I suppose it's not a terrible operational service life if it went in in 1980, but I wouldn't build with them. I'd like to know what the heck they are to reference them in a report I'm drawing up though. Maybe it's worth a crosspost to the structural forum?

Probably rejects or second that were solid/used for another purpose. Usually, the manufacture marks then as rejects or similar to insure they are not drawn into future liabilities.

Since they are about 24" long, you have to pick up one end of the duct to slip some cans out. Magnets do not work on aluminum cans, so you have to rely on gravity.

for running multiple utilities (elec, tel, fiber optic, cable tv etc.)
in one trench. These look like they were not used as a retaining wall,
just left over from previous work or a project that never got passed the product delivery stage.

It appears that the duct bank design depicted in your posted
image is no longer being produced. At least I could not
find any precast concrete company still producing that particular style.
View the video to see the new-improved (watertight)
styles.

What year was your wall constructed, Buster?

We now know that duct banks don't make good retaining walls.
