Ex- cavation anterior to the eye shallow, scaniely distinct in passing under the eye to the tympanum. Tynipamim very large, one-fourth greater than the eye, and extending (piite ujt to it, and beyond the ar- ti(!idation of the Jaw; one-half the length of line from commissure to the tip of snout; its central third elevated in a shallow prominence. Eyes large, contained two and three-fourtli times in chord of lower Jaw and two and one-fourth in that from (commissure. IJead rather larger than broad. In the female the tympanum is much smaller, though still large; about three-fourths diameter of eye, and distant from the latter by nearly half its own diameter. The average diameter in males is 11""", and in fe- males 8" Occasionallv this character does not hold good, A male (No. ;>1(!2) has the diameter only S""", while three females (Nos. 3407, 'Silo, and ',)~)2l) have disks of 10 in diameter.
