Eocaecilia micropodia, MNA V8062, dorsolateral view of a partial skull of which only the anterior part is preserved. The lacrimal bone presents the most equivocal case for interpretation of any of the skull roof elements. In the only spec- imen for which the lateral surface of the antorbital region is articulated (MNA V8062, Fig. 8), there appears to be a nar- row triangular space between the posterior portion of the prefrontal and maxilla that might have been occupied by a lacrimal. Although a lacrimal is not known in the adult of any Recent caecilian, a separate element in the nasal region of embryonic Ichthyophis glutinosus was identified by Peter (1898, fig. 20) as a turbinale (= lac- rimal). Similarly, Marcus et al. (1935, fig. 5) identified a lacrimal in their reconstruc- tion of a 68-mm embryo of Grandisonia alterans (cf. Wake and Hanken, 1982, ta- ble 1). Wake and Hanken (1982), however, found no evidence of a separate lacrimal ossification center in their study of Der- mophis mexicanus; in view of their cau- tionary assessment of the evidence pre- sented by Marcus et al. (1935) for multiple ossification centers (including that for the quadratojugal, postparietal, periorbital, ec- topterygoid, and interparietal), the fate of the lacrimal "in caecilian history must be regarded as unresolved. The premaxilla, which does not appear to overhang the lower jaw as it does in many Recent caecilians, has a long poster- odorsal process that fits into a slot in the nasal and a very narrow extension that oc- cupies a groove along the anterodorsal margin of the maxilla. As is the case for almost all specimens of upper and lower jaws, the crowns of the teeth have disar- ticulated postmortem from the pedicels; only in the premaxilla of MNA V9346 do a few crowns appear to be preserved in situ.
