The groups dealt with in this volume are not only of the highest scientific interest and importance, but they present more than ordinary difficulties to be investigated, and these difficulties are materially increased when stern necessity compels the several contributors to condense their work within the smallest possible limits. Happily this task has fallen on the right shoulders, and all must admire the way in which it has been performed.

The first chapter of this book has been written by Dr. S. F. Harmer, and deals with the Hemichordata, a group which includes creatures of the existence of which the layman has never heard! Yet their importance in the scheme of evolution is of the highest, inasmuch as they bridge the gap for us between vertebrates and invertebrates.

The true nature of these worm-like and tubicolous animals has been determined only after the most laborious and painstaking research, in which Dr. Harmer, the author of this chapter has borne a very conspicuous share. Though the vertebrate affinities of the worm-like Balanoglossus were first hinted at by Kowalewsky in 1866, it was not until 1886 that this relationship was really demonstrated : a triumph achieved by Bateson. Forming at first a branch by itself of the vertebrate phylum, Balanoglossus has since lost something of its unique character by the discovery that certain other tubicolous formsRhabdopleura and Cephalodiscus-would have to be Fig. 1.-Embryos of Rhodeus amarus in the gill-cavities of Unio. promoted to share this position, though to the ordinary , Embryos ; &, inter-lamellar cavities.

Such a review would serve a matic position of Palæospondylus by placing them in double purpose. It would keep alive the memory of a sort of limbo designated an " appendix to the those whose names are all too soon forgotten, and it fishes.” would serve as an incentive to further work.

In this same appendix it is somewhat surprising to Probably this survey would not have been wanting, find not only the Ostracoderms, but the Arthrodira! but for the fact that some two hundred and eighty of As touching the former Prof. Bridge may claim that the seven hundred and twenty-seven pages which mak. he errs, if erring he is, in good company, since so up the book are devoted to the introduction on fishes! eminent an authority as Dr. Smith Woodward refuses This is not as it should be ; on this account serious to admit these “bones of contention " into the class

Pisces. But we object to the hesitancy displayed by Prof. Bridge; he will neither call them fishes nor allow them to rank as a separate class (Agnatha), as Dr. Woodward has done. But surely there can be no question as to the class, at least, to which the Arthrodira belong? According to the most recent views they are to be regarded as Dipnoans.

In spite of these drawbacks Prof. Bridge's contribution to this volume is a valuable one. He has brought together a vast amount of information, much of which is the result of his own researches. Where he has had to draw upon the work of others he has for the most part selected of the best. Our chief complaint is that he is so meticulously exact.

The Teleostei, from a systematic point of view, are described by Mr. E. A. Boulenger, and he has brought to bear upon this most difficult task an unrivalled knowledge, tempered with rare skill and judgment. The classification which has been generally in use in this country for the last thirty years is now replaced by one which aims at being phylogenetic-the true basis of all systematic work. Although we believe Mr. Boulenger has improved on this arrangement in some minor details since passing the final proofs of his work some three years ago, it may be accepted as practically representing his views on this subject.

As he remarks, “Out of some 12,000 well

From his almost inaccessible stronghold, the Paharia looked down upon the coming and going of the Hindu, the Pathan, and the Moghul. Empires rose and fell before his very eves whilst he, hating the foreigner of every race and creed, remained wrapped in his primitive barbarism, a hunter living on the produce of the surrounding forest, not to be starved into submission, because he had no need of the produce of the plains. His only dealings with successive invaders were when he swooped on the villages below, killing and robbing their inhabitants, or cutting off travellers and the camp followers of passing armies. Veither Hindu nor Mahomedan could subdue him by main force without extravagant loss.
