The specimens represent the characters of the Siwalik early hipparionineSivalhippus nagriensis: anterostyle elongated in P2, increasing crown height of maxillary teeth with multiple plications on the posterior border of prefossette and the anterior border of postfossettes, bifid to trifid
plicaballins, oval protocone flattened lingually and rounded labially, and hypoglyph deeply incised (Hussain, 1971; MacFadden and Woodburne, 1982; Bernor and Hussain, 1985; Wolf et al., 2013).
Leaves opposite, rarely verticillate or alternate, composite, 2-3-foliolate, ternate, pinnate, bipinnate or digitate, rarely simple, entire, crenate or serrate, venation pinnatinerved to palmatinerved; in lianas terminal leaflet can be substituted by tendril (simple, bifid, trifid

Genus Ornithoctona Speiser, 1902, is recognized by the following characteristics: antennal pedicel, as viewed from above, broadened, leaf-like, 2-3 times as long as wide; antennae separated from each other by less than width of one antenna; thoracic sterna bare or at most with soft recumbent setae; scutellum with less than 30 anterior short bristles which are not arranged to form a comb; laterotergite without prominent projection; wings functional, with vein Cu[A.sub.2] forming a closed cell cup and tarsi with apical tooth of claw deeply cleft so the entire claw seems trifid
The lower incisors are small with a trifid

canal, unilateral, and Clays & Wackens (2005) who described a case of two mandibular canals, unilateral rights, starting from the distinct mandibular foramina and ending in separate foramina.
Up from the spout come a plethora of pufflike nebulae--the Lagoon (M8), Trifid
