Some- times these fangs are divided into two points, near their base, and each of these points has, perhaps, heen sometimes considered as a distinct fang. The bicuspides, or first two grinders, on each side, have in general only one fang. This complement of teeth is, however, some- times deficient; and of the various cases of this description which have, in the course of his practice, come under the author's notice, plate vi, figs.
