FERAE. 
SUB-ORDERS. 
I. Body more or less raised, with the legs exserted beyond the elbows and 
knees, and with the feet (generally with free toes) adapted for walking. 
Manus and pes with first phalanges and digits not enlarged nor produced 
beyond the others (attypically more or less reduced or even atrophied). 
Skull moderately compressed between the orbits: with a distinct lachry- 
mal bone, perforated by a canal (the lachrymal), and more or less exserted 
outside the orbit, and, in conjunction with the malar, forming the anterior 
margin of the orbit: palatines extending forwards laterally between the 
frontal and maxillary bones, and leaving no vacuity. Tympanie bound- 
ed behind by the exoccipital. Deciduous dentition well developed.

II. Body prone, with the legs confined in the common integument beyond 
the elbows and knees, (with the feet rotated backwards, and with toes con- 
nected together), and especially adapted for swimming. Manus and pes 
with first phalanges and digits enlarged and produced beyond the others. 
Skull much compressed between the orbits: with a lachrymal bone early 
united with the maxillary, imperforate, and entirely contained within the 
orbit: malar applied to the inner side of a transverse zygomatic process of 
the maxillary and not continued to the front of the orbit (which is there- 
fore bounded by the maxillary): palatines not extending forwards later- 
ally, extensive vacuities intervening between the frontal and maxillary 
bones. Tympanic separated from the exoccipitals by a vacuity as well as 
by the re-entering periotic bones. Deciduous dentition much reduced 
and rudimentary. ¥
