It is proportionally similar to De Winton’s Brown-toothed Shrew (C. hypsibia ). Dorsal pelage is dark gray, and ventral pelage is slightly paler gray. Tail is shorter than head-body length. Small tuft of hair occurs attip of tail. Skull is small, and braincase is flattened. There are three upper unicuspids that slightly overlap.
