 at half an inch from the tip of the nasal bone is 5^ 

 lines, whilst the same part measures in H. micropus, 

 6 lines. The molar teeth of H. murinus are longer 

 than broad, whilst in H. micropus their length and 

 width are equal, the length of the five molars on 

 each side of the upper jaw in H. micropus is 9 

 lines ; those in H. murinus measure rather more 

 than 1 1 lines. Length of skull of H. micropus, 3 

 inches ; width, 1 inch 6^ lines. 



Section 2. Hypsiprymni with comparatively short
