I came across this publication for finding ancestors in the UK or Ireland in the 1860s.
It says for the month ending January 1, 1861 on the cover but the first section is 1860 and mostly December but there are some records as early as September. The next section is 1861 and goes through the whole year.
This paper "entered at Stationer's Hall" was published monthly and distributed to subscribers in all the colonies.
Also has an "alphabetic list of estates of deceased persons, upon which claims will be barred unless made on or before the particular dates"
