ly compressed, and
bordered above and beneath by a dermal fold.

In _Hypogeophis_, a Caecilian from the Seychelles studied by A. Brauer, the
development resembles that of _Ichthyophis_, but there is no aquatic larval
stage. The young leaves the egg in the perfect condition, and at once leads
a terrestrial life like its parents. In accordance with this abbreviated
development, the caudal membranous crest does not exist, and the branchial
aperture closes as soon as the external gills disappear.

In the South American _Typhlonectes_, and in the _Dermophis_ from the
Island of St Thome, West Africa, the young are brought forth alive, in the
former as larvae with external gills, and in the latter in the perfect
air-breathing condition.

CAECILIA, VIA, an ancient highroad of Italy, which diverged from the Via
Salaria at the 35th m. from Rome, and ran by Amiternum to the Adriatic
coast, passing probably by Hadria. A branch ran to Interamna Praetuttiorum
(Teramo) and thence probably to the sea at Castrum Novum (Giulianova), a
distance of about 151 m. from Rome. It was probably constructed by L.
Caecilius Metellus Diadematus (consul in 117 B.C.).

CAECILIUS, of Calacte ([Greek: Kale Akte]) in Sicily, Greek rhetorician,
flourished at Rome during the reign of Augustus. Originally called
Archagathus, he took the name of Caecilius from his patron, one of the
Metelli. According to Suidas, he was by birth a Jew. Next to Dionysius of
Halicarnassus, he was the most important critic and rhetorician of the
Augustan age. Only fragments are extant of his numerous and important
works
