xiv INTRODUCTION form the bulk of the subjects of the Thangur chiefs. In this monograph Lushai is used in this wider sense, Lushei being used only for the clan of that name. Among the people them" selves the Lusheis are sometimes spoken of as Dulian, at the derivation of which I will hazard no guess, and the general population of the hills is spoken of as Mi-zo. Among inhabi- tants of the Lushai Hills are found a very considerable number * of immigrants, or descendants of immigrants from the Chin Hills, who are found living among the Lushais under the Thangur Chiefs or in villages under their own chiefs. I have made no attempt to deal with these, as their proper place is the Chin Hills monograph, and Messrs. Carey and Tuck have already described them very fully in their Chin Hills Gazetteer. I am conscious that there are many omissions in this book; the subject is a very wide one and the difficulty of getting at the facts from so many different clans, each speaking a different dialect and scattered over an area of about 25,000 square miles is extremely great. I trust therefore that my readers will excuse all shortcomings. I have purposely avoided enunciating any theories and making deductions, considering it wiser to limit myself to as accurate a description as possible of the people, their habits, customs and beliefs. Regarding the affinities between the clans dealt with in this monograph and those described in tha other books of the series, I venture to express a hope that the subject may be dealt with by some competent authority when the whole series has been published; until this is done no finality will be reached. It would be easy to fill several pages with points of resemblance between the different clans. Major Playfair, in his account of the Garos, has pointed out many ways in which the subjects of his monograph resemble the inhabitants of the Naga Hills, but reading his book I find many more in which they are like the clans I am dealing with. Sir Charles Lyall has drawn attention to the evident connection between the Mikirs and the Kuki-Chin group; I venture to think that a study of the following pages will confirm his theory. I may mention here that the main incidents of the " Tale of a Frog " given by Sir Charles are found not only in
