L r Hiid snbround crowns, which alternate with those 
of the median row, and are therefore separated by spaces equal 
to their tiwii diameters. The anterior two median teeth are 
ihinkiHl each by a very small tooth of the first lateral row, and 
the same is true of the posterior tooth. The number of teeth 
in this n»w is thu.s eight. The teeth of the external row are 
Isith iipiM»site nml alternate to those of the median row; and they 
are ther«*foie in contact and more uuinerous, numbering ten on 
each side. Their transvei'se diameter is generally a little 
«n‘Mier than their anlen»|>osterior. The lateral borders of the dental tract are 
parallel. None of the crowns are inipresseil.
