terminal half of the tail black which is continued into the median black line on the middle 

 of the back. Across the forehead a broad white band, extending on the neck to behind

 The skull resembles tliat of Paradox ur us hermaphroditus Pall., but is larger 

 and more robust. The bulla* are very high and slightly rounded off anteriorly. The last 

 mol ar is ratlier small, much smaller than in true P. hermaphroditus Pall. or P. herma- 

 phroditus ravus Miller.

The Crab-eating Mungoose was exceedingly common in the forests on the boundary 

 between Siarn and Tenasserim. It seems to be somewhat aquatic and all the specimens 

 obtained were shot at the numerous small »nongs » which were f ound in that region. They 

 were gencrally seen in pairs coming down to feed or to drink and were very quick and agilc 

 in theår behavior. Tlie drawing in Blandford's Mammalia of British India, Ceylon and 

 Burma is quite excellent and shows exactly the behavior and position of this species 

 when coming down to drink. 



The whole series is very uniform as to the general colouration. In old specimens 

 with much worn teeth the orbits are quite closed.
