REPORT ON THE INVERTEBRATES. 



By J. Walter Fewkes. 



My time in Cambridge last year was occupied in work on the 

 Atlantic Room, which, much to my regret, I was unable to finish. 



A part of July and August was spent at Grand Menan, where 

 I was engaged in a study of the development of Pteraster and 

 certain other Echinoderms. 



I wish to be permitted in this, my last Report, to express my 

 gratitude for the opportunities for research which have been 

 afforded me during the eight years in which I have been officially 

 connected with the Museum. 



The following papers have been printed for me during the past 

 year : —

 careous Plates of the Starfishes. Proc. Bost. Soc. Nat. Hist., Vol. XXIV. 

 pp. 96-117.
