A crop-like dilatation of the gut and a recurved intestine, embedded in the compact yellowish-brown liver, the ducts of which open into it, form the rest of the digestive tract and occupy a large bulk of the visceral hump. The buccal region presents a pair of shelly jaws placed laterally upon the lips, and a wide range of variation in the form of the denticles of the lingual ribbon or radula.
Special to the Heteropoda is the high elaboration of the lingual ribbon, and, as an agreement with some of the opisthobranchiate Euthyneura, but as a difference from the Pectinibranchia, we find the otocysts closely attached to the cerebral ganglia.
The alimentary canal commences with the usual buccal mass; the lips are cartilaginous, but not armed with horny jaws, though these are common in other Opisthobranchs; the lingual ribbon is multidenticulate, and a pair of salivary glands pour in their secretion.
It chanced that there existed on the polished surface of a cliff at Behistun in western Persia a tri-lingual inscription which, according to Diodorus, had been made by Queen Semiramis of Nineveh, but which, as is now known, was really the work of King Darius.
Hospitals, orphanages, schools and an admirable college in Seoul have been founded, along with tri-lingual (Chinese, Korean and English) printing-presses; religious, historical and scientific works and much of the Bible have been translated into En-mun, and periodicals of an enlightened nature in the Korean script are also circulated.
Nor is the question of the vernacular itself of necessity bound up with this new movement, for Wales is essentially a bi-lingual country, wherein every educated Cymro speaks and writes English with ease, and where also large towns and whole districts - such as Cardiff, south Monmouth, the Vale of Glamorgan, Gower, south Glamorgan, south Pembroke, east Flint, Radnorshire and Breconshire - remain practically monoglot English-speaking.
There is, however, good embryological evidence in some Hexapods of the existence of a seventh somite, the supra-lingual, occurring between the somite of the mandibles and the somite of the first maxillae (4).
Recent investigations (Folsom, 4) show the existence in the embryo of a prae-maxillary or supra-lingual somite which is suppressed during development.
Lingual r at the end of a word has a tendency to disappear when preceded by a vowel: thus the infinitives amare,temere, *legire are pronounced amd, tem, ilegi.
R, Lingual sac (radular sac).
The latter do, indeed, exist in the case of the Cretan civilization and in great numbers; but they are undeciphered and likely to remain so, except in the improbable event of the discovery of a long bi-lingual text, partly couched in some familiar script and language.
Like other Euthyneura, they have very numerous small denticles on the lingual ribbon.
