E. RAY LANKESTER. lil 
Every reader will remember that Professor Lankester’s 
energy has by no means been exhausted in merely editing the 
Journal, for besides his many writings elsewhere, he has pub- 
lished more than sixty memoirs in the pages of this Journal 
alone ; and we may, perhaps, be permitted to mention a few of 
. the more prominent of these—such as that on ‘‘ The Develop- 
ment of the Pond Snail” (1874), which marks the starting- 
point of his well-known investigation of the development of 
Mollusca; the “Notes on the Embryology and Classification 
of the Animal Kingdom” (1877), which exercised so great an 
influence upon the whole tendency of morphological specula- 
tion; the descriptions of Limnocodium (1880) ; the series of 
memoirs on Apus and Limulus (1881—1884), and on Rhabdo- 
pleura (1884) ; the first description of the atrio-ccelomic funnels 
in Amphioxus (1875), and the subsequent memoir on the ana- 
tomy of the same animal, together with the account, commenced 
in conjunction with his pupil Mr. Willey, and continued by 
Mr. Willey alone, of the later history of its remarkable larva. 
It would be useless to enumerate all the naturalists who 
have contributed to the Journal since Professor Lankester’s 
successful enterprise has made it the chief medium of publica- 
tion for English morphological work; but it is interesting to 
notice that the contributors have constantly included foreign 
naturalists of distinction, including E. van Beneden, Bow- 
ditch, Carriére, Claparéde, Dollo, Giard, Hubrecht, Iijima, 
Ischikawa, Kingsley, Mitsukuri, H. F. Osborn, Oudemans, 
Packard, Patten, Pelseneer, Pouchet, Ranvier, Whitman, and 
others. Some of these have taken the opportunity, by contri- 
buting to the present number, of joining in the hearty con- 
gratulation on his past achievement, and sincere good wishes 
for the future, which Professor Lankester’s associates now 
offer to their chief.
