Auk, (lat. alca): this bird occurs in the following arms, and as in another blazoning of the same arms the term murr occurs instead of auk, we may presume that it is synonymous. The name Razor-bill(alca torda) also occurs on one coats of arms.
Or, a chevron sable between three auks(or murrs) proper--CARTHEU, Cornwall.
Or, the head of an auk proper--AUKES.
Argent, three razor-bill's heads, couped sable--BRUNSTAUGH.
