melius inquirendum vel inquirendo

from Bouvier's Law Dictionary, Revised 6th Ed (1856)
MELIUS INQUIRENDUM VEL INQUIRENDO. English practice. A writ which in certain 
cases issues after an imperfect inquisition returned on a capias utlugatum 
in outlawry. This melius inquirendum commands the sheriff to summon another 
inquest in order that the value, &c., of lands, &c., may be better or more 
correctly ascertained. Its use is rare.
