The 1841 census transcription at
www.freecen.org.uk lists it as Mullans and the 1851 says Village of Mallions.
The places in the enumeration district in 1851 are Glenhead, Craigdouffie, Slacks, Drumnessie, Berryhill, Crossmyloof, Bentend, Waterside, Slachristock, Slafarqhuar, Spittal, Burnhouse, Brockieside, Riskend, Auchinvalley, Auchinrivoch, Village of Banton, Village of Engine, Village of Mallions, Village of Auchinvalley and Valleybank House. Look at the old map I gave you the link to. You can just about follow the route the enumerator walked from one place to another, assuming that the place marked Low Banton is the Village of Auchinvalley (there being nowhere esle big enough in the enumeration district).
Can you still doubt that the place you have transcribed as Malliows is the one that FreeCen has as Mullans in 1841 and Mallions in 1851 is the place marked Maillings on the map?
