In each there are two small circular, transparent areas, opposite the mandibles. The mouth-parts (fig. 2) consist of a labrum, maxillae and ligular area which border the preoral cavity, and the mandibles. Both the labral and mandibular struts bear condyles for the articulation of the mandibles, which are somewhat bluntly pointed, and are without teeth. Anterior to the mandibles, on the ventral edge of the clypeus, are two pairs of low, rounded papillae.

The mandibles were taken from frozen specimens, the heads of which were thawed for 10 min and the skin and underlying fat removed. Neither the mandibles nor the maxillae bear the scraping and cutting that would be expected with defleshing. The mandibles were all well articulated with the crania and the atlas vertebrae all still present. The mandibles and scleromes of the mouth-parts are brown and prominent. The mandibles are short and blunt, with their points anteriorly directed. The only highly sclerotized parts of the head-capsule are the mandibles, which are elongate, curved, and unserrated. The mandibles are about 0-025 mm. long, and sharply pointed. The mandibles were left to dry for 2 days at room temperature. First, the fact that ar ticulated mandibles and cervical ver tebrae were recovered along with the skulls indicates that the skulls were interred at least par tially ar ticulated. Using additional skull measurement may have improved slightly the precision of these estimations, but to the detriment of sample sizes as mandibles were by far better preserved than skulls. An intended victim, depending on how it was gripped, was often physically unable to reach the attacker with its mandibles, despite visibly contorting its body in attempts to do so.
