We present 8--15 {mu}m spectra of ULAS J003402.77-005206.7, and extremely late-type T dwarf. We fit synthetic spectra to the near- through mid-infrared energy distribution of this dwarf, as well as to the near-infrared spectra of two similar dwarfs, ULAS J133553.45+113005.2 and CFBDS J005910.82-011401.3. The fit to ULAS J133553.45+113005.2 is constrained using mid-infrared photometry. We derive effective temperatures of 550--600 K for all three of these T9 dwarfs; ULAS J003402.77-005206.7 appears to be the least massive (5--30 M{sub Jup}), and CFBDS J005910.82-011401.3 the most massive (30--50 M{sub Jup}).
