Davis 141. Iguana 3 mi. W. Monte Cristóme, 650', Dept Morazan, El Salvador, Dec. 1, 1941. 9-10 a.m. we took to be young. Hildbrand climbed the free and attempted to drive the large ? toward the junk over land, but it made its way slowly to the end of the limb out over the water. We proceeded up the bank to ano- ther tree where we spotted small green spe- cimens. Seitz shot # through the head and we recovered it after it fell to the ground. (899). On skinning, it turned out to be an adult ?, containing 31 spherical eggs, yellowish orange in color, about 3/4" in diameter. We then returned to the tree where we had spot- ted the large ?. It had crawled to a lower branch over land, and Seitz dropped it with a head shot. It was 1420 mm. from snout to tip of tail, and registered 10 lbs. on a small fish scale (900). Color light red scattered in blotches over a fawn ground color. Gular flap dark red. The 2 large pouches behind the angle of the jaws proved to be huge extensions of the masseter muscle. In both ? and ?, there are 2 large effusions of one of the hyoid bones extending into the gular pouch, which evidently enable the lizard to move it in display.
