These objects exhibit unusually low abundances of Mg, Si, Ca (alpha-elements) and Sr, Y, and Ba (neutron-capture elements). Our analyses confirm and expand upon earlier reports of atypical abundances in BD+80~245, G4-36, and CS22966-043. We also find that the latter two stars exhibit enhanced abundances of Cr, Mn, Ni, and Zn (iron-peak elements), along with what appears to be large abundances of Ga, with respect to the abundance of iron.
