From a Hunterian specimen in the Museum of the College of Surgeons. On the left side there are three rows of small lateral teeth while on the right side two of these rows are represented by one row, which in places shows an indication of division. Lower Diagram. Bhinoptera javanica, in which the row of teeth marked I. is on the other side represented by two rows. (After Owen, ' Odontography,' pi. xxv. fig 2 From a specimen in Coll. Surg. Mus.)
