Central tooth rectangular, the length more than twice the breadth ; the 
reflexed portion triangular, slightly sinuated on the sides, about half the 
length of the base and with a moderate point. Inner laterals like the 
central tooth, but more deeply sinuated on the inner side; outer laterals 
bicuspid, the inner cusp larger and with a long point, the outer cusp with a 
small point. Inner marginals with a long acute point, and a small one 
inside it; outer marginals with the base as long as broad, and a single long 
point. The cutting points increase in size as far as the middle of the 
marginals and then decrease.
