Add entry to beginning of list and remove the last one

I have a list of about 40 entries. And I frequently want to append an item to the start of the list (with id 0) and want to delete the last entry (with id 40) of the list.

How do I do this the best?

Example with 5 entries:

[0] = "herp"
[1] = "derp"
[2] = "blah"
[3] = "what"
[4] = "da..."

after adding "wuggah" and deleting last it should be like:

[0] = "wuggah"
[1] = "herp"
[2] = "derp"
[3] = "blah"
[4] = "what"

And I don't want to end up manually moving them one after another all of the entries to the next id.
