AB - Abstract Attempts were made to ascertain the age of a wild-caught Phenacomys ungava, within rather close limits, by comparing its skull with those of a series of known-age phenacomys. Such comparisons are not valid, since the laboratory voles do not develop exactly as do those in the wild. Rather, one may only comment that great care must be taken when comparing laboratory data with data gathered under natural conditions. It is demonstrated that the rostrum of phenacomys continues to grow throughout the first year of its life and that this may be used in approximating its age more closely than has been hitherto possible. Degree of extension of teeth is also quite useful in calculating age. Literature Cited Bond Charles F. 1956 . Correlations between reproductive condition and skull characteristics of beaver . J.
