Assistance with terminology

I have seen several death records from Asientos in the mid 1790s with a clause similar to "se entierro menor en fabrica de quatro pesos seis reales".

Other records are annotated "limosna," which I assume means the person was poor, and was buried without a donation or payment to the Church.

When I try a computer translation of this clause (such as with google), the result makes no sense.

Is this amount a donation, or is this what it cost to be buried by the Church.
