This species is slightly larger than the common mouse; the head is rather
larger in proportion; the ears are rather smaller and more distinctly clothed with
hair; the tail and tarsi are much longer in proportion. Its bright yellow colouring
and proportions distinguish it from any of the species described in this work. Of
this animat I do not possess the skull, nor of the teeth do I possess more than the
first and second molars of the upper jaw, and the second and last of the lower
jaw. These are figured in Plate 34, figs. 5. a, and S . b.
