to Dr. Herdman, the President of the Linn.ean Society, for the eighty pages in which 
he deals with the ascidians, and still more for the succeeding five-and-twenty that 
summarise our knowledge of better known as Amphioxus. Sec- 
tions dealing with the varied and brilliant colouration of fishes, their poison- 
glands, phosphorescent, sound-producing and electric organs, serve to show that 
anatomy and classification by no means occupy the entire volume ; whilst the 
two specimens of the 440 illustrations, which, through the courtesy of Messrs. 
Macmillan, we are able to reproduce, the one of the lancelet at home, and the 
other a remarkable example of protective resemblance in an Australian sea-horse, 
serve to emphasise the many-sided interest of this admirable piece of work.
