A preliminary $BVRIJHK$ analysis of the white dwarfs SSSPM J2231$-$7514 andSSSPM J2231$-$7515 is presented. Although both stars were reported to have$T_{\rm eff}<4000$ K, the analysis here indicates $T_{\rm eff}\approx4250$ Kfor both SSSPM J2231$-$7514 and SSSPM J2231$-$7515. Given substantialscientific interest in the coolest extant degenerate stars, it is necessary todistinguish sub 4000 K objects from the bulk of cool white dwarfs. Thisanalysis reiterates the importance of near infrared observations inconstraining the spectral energy distributions and effective temperatures ofthe coolest white dwarfs and briefly discusses their possible origins.Comment: 9 pages, 4 figures, 1 table, accepted to A
