44 MYDAUS MELICEPS. 



British Museum , which seem to vary in the extension 

 of the white dorsal line like our Java-specimens , hrowii 

 colored. 



Mr. Charles Hose gives in his very important paper, 

 entitled »a descriptive account of the Mammals of Borneo", 

 the following definition of the color of Everett's Mydaus : 

 »Back black; crown white, reaching to the middle of back." 

 No word about size of the animal or skull. 



The back of our specimen from E.-S.-E. Borneo has a 

 black color ; the fur is coarse and very short for a Mydaus- 

 specimen of such a rather small size ; the large white 

 crown-spot reaches not beyond the shoulderblades , a very 

 narrow white line from the middle of the back to the 

 root of tail, basal part of tail black like the back, end 

 of tail white. This specimen, a female, makes the impression 

 as if halfgrown, as it measures from tip of muzzle to 

 root of tail about (it is a stuffed specimen) 37.5 cm., an 

 examination of its skull shows however that it is by far 

 not what it exteriorly let suppose , for , as all the bones 

 are firmly ankylosed , it ought to belong to an elder spe- 

 cimen although it is in all dimensions of the same size 

 as a halfgrown Java-individual. Compared with the above 

 mentioned large skull with distinctly visible sutures, we note 

 the following measurements : 



Of a very great importance are the lower jaws : the figures 

 (see next page) present the differences in size and shape 

 very distinctly, the uppermost figure is that of the Java- 

 skull, the lower one that of the Borneo-skull. The denti- 

 tion demonstrates that in fact the smallest skull is the 

 eldest, all the teeth being more used off. 



Finally our specimen from the Calamianes-islands. It
