Rh which appeared in zoological literature towards the end of the last century, we may well take heart and fresh courage.

A separate issue of seventeen beautifully coloured plates accompany the volume for those who wish to acquire the same, and we trust that the author may have health and strength to finish the colossal undertaking. Meanwhile, as years must elapse before the whole of these volumes can be issued, it would be advantageous to the classificatory scheme of the author, and most useful to workers who would fall in line with the classification, if the names of existing genera under new family arrangements could be published elsewhere, and at an early date.
