The absence of caniniform enlargement and the extension of the maxilla dorsad of the narisexclude Delorhynchus from the Eothyrididae (Ophiacodontia) but are no bar to its inclusion in the Nitosauridae (Edaphosauria).
Resemblances to the caseids are to be noted in the enlargement of the naris (4.
At the posteroventral corner of the naris a foramen opens onto the lateral surface of the maxilla.
Beneath the naris the maxilla extends as a broad tapering shelf, the ventral surface of which articulates with the premaxilla.
The maxilla encircles the posterior border of the naris and extends dorsally above the naris to an extent sufficient to indicate the probable exclusion of the lacrimal bone from the narial border.
The naris in each is enlarged, and the lacrimal is excluded from the narial margin in each (by inference in Delorhynchus.
The maxillary begins at a suture with the premaxillary lateral to the naris and continues posteriorly, bordering the orbit with a width of about 1.
The maxillary meets the premaxillary lateral to the naris, borders the naris posteroventrally, and continues posteriorly beneath the orbit, of which it forms the external border.
It is slightly anterodorsal to the internal naris and 4.
A groove, but not a complete division of the nasal, is present above the leftnaris of one specimen.
One specimen lacks the typical division below the naris on both sides, but a complete suture is present posterior to the naris and the resulting postnasal scales are, according to position, loreals.
The restored anterior naris is kept patent, as already described, till healing takes place.
If the web obstructing the anterior naris be more fleshy in character (and it is more apt to be of this nature when it is incomplete), it may be necessary to remove it with a knife.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "naris" in a variety of sentences. We hope that you will now be able to make sentences using this word.
