WHILST the tonal languages spoken in West Africa have latterly received W a good deal of attention, it has not been generally realized that such languages are found also in parts of New Guinea. In New Guinea there are in fact two types of tonal languages. In one, the tones may be described as ” ornamental”, i.e. though they exist they do not seem to have semantic value, but rather to be connected with a certain type of sentence rhythm; in the other the tone systems are more definitely akin to those of Western Africa, and in such languages tones do possess semantic value. It is interesting that one at least of the latter group of languages tends also to be monosyllabic. It is hoped to provide a study of the former class of languages—at least one representative of which is also found in Northern Australia—at a later date. The present paper is occupied with the languages in which tones do have semantic value.

These languages, so far as has been observed yet, are two in number, and they are spoken along the shores of Huon Gulf, in north-eastern New Guinea. The map on p. 186 will show their locations. Both belong to the group of languages known as Melanesian, and this makes the occurrence of tones even less expected. A considerable number of other languages are spoken round about this area, and though some of these also are Melanesian, they do not seem to have developed tones. Moreover, it would seem that the use of tones in these two languages antedates the coming of the Melanesian languages, for reasons that will be given towards the end of this paper.
