There might perhaps also be reason to fix such names as 

 Sulenia, Eclnnometra, Psammichinus, Moira, and others, and 

 also Cidaris and Dorocidaris might be taken into considera- 

 tion. Nobody, I think, will deny that it would be desirable 

 to keep the name Dorocidaris, so much used in literature ; 

 Cidaris would then naturally get metuluria as its genotype. 



To have fixed all the generic names of Echinoidea with 

 their genotypes would, of course, be the best. But if only 

 the above names (and some names of fossil genera ought, 

 perhaps, to be added, as, e. g., Ananchytes) were secured, 

 much stability would follow. The end of it should be the 

 making of a complete Codex NOMINUM, containing all the 

 generic names of the animal kingdom, with their genotypes 

 given.

The fact that for more than a generation the standard text-hooks 

 on Zoology in use in this country have been translations from the 

 German or French has been due, not so much to the lack of compe- 

 tent teachers, as to the generous appreciation which we have always 

 shown of what is good in our neighbours. That this attitude 

 redounds to our credit is undeniable. Furthermore, it argues the 

 conviction that no great benefit to science could accrue from the 

 production of a " home-made ' book so long as that book was, like 

 its continental forerunners, the work of a single author ; for of 

 necessity it could not pretend to be more than a compilation — though 

 a good compilation needs a wide grasp of facts and wise discrimina- 

 tion. Realizing this, Sir Ray Lankester set himself the task of
