ment shown in their selection are almost beyond criticism. Why 
the Gephyrea and the Hirudinea are placed above the more 
highly specialized Chztopod worms we do not understand. As 
also why the Phyllopods should be placed at the base of the 
Crustacea, below the Copepoda and barnacles. This classification 
has been strenuously advocated by Claus, but not, we suppose, 
generally accepted; the reasons militating against this view are 
many and urgent; the Branchipodide, with their stalked eyes 
and highly specialized bodies, appear to stand nearer the stalked- 
eyed Crustacea than any other Entomostraca ; and to go directly 
from the root-barnacles to the Malacostraca is straining more than 
one point in taxonomy. In treating the trilobites no reference 
whatever fs made to American work, especially that of Walcott, 
who has demonstrated that they had hard jointed limbs; Claus 
states the obsolete view that they were “ soft and delicate.” 
Among the Myriopods Pauropus is assigned to the Polydes- 
midz, when it certainly represents a distinct suborder if not 
order. The Physopoda or Thrips are regarded as a tribe of 
Pseudo-neuroptera, although embryology shows they are Hem- 
iptera. The taxonomy of the Lepidoptera seems to us to be very 
objectionable and old-fashioned, while it is a comfort to see that 
e Hymenoptera are placed at the head of the insect series. We 
shall look with great interest to the appearance of the second, 
closing volume. 
Goopa.e’s Puystotocicat Borany..—In the year 1879 Dr. 
Gray brought out the new (sixth) edition of his widely known . 
and used Botanical Text-book. The new book covered much 
less ground than the older editions, being confined to the structural 
botany of the phanerogams. It was then announced that Dr. 
Goodale was to prepare a second volume to be devoted to physio- 
logical botany, Dr. Farlow a third devoted to cryptogamic bot- 
any, and that the series was to be completed by a fourth volume 
to include a sketch of the natural orders of phanerogams. After 
waiting six years we have the pleasure of perusing advance 
sheets of the long-promised Vol. 1. The part before us is de- 
voted to the histology of the phanerogams, and is soon to be fol- 
lowed by Part 11, which is to deal with vegetable physiology. 
Upon opening the book we have first an interesting chapter 
devoted to histological appliances ; a most useful chapter indeed 
it will prove to all workers in the botanical laboratory. In this 
we observe with pleasure the remark that “other things being 
equal, a microscope with a short tube and with a low stand will be 
most convenient on account of the large number of cases in which
