Anatomy and Physiology. 
Aster acanthion rubens. Jourdain, 1. c., in giving a brief sketch of the cir- 
culatory system of this Starfish, states that, in spite of researches carefully 
conducted for a lengthened period, ho has been unable to discover the com- 
plex vascular system generally admitted by anatomists on the faith of the 
researches of Tiedemann and Volkmann. Their .supposed heart would ap- 
pear to be but a glandular organ. The autlior describes the collection of 
vascular cavities as an ambulacra! hydrolymphatic system which communi- 
cates with the exterior, consisting of an oval ring situated below the nervous 
collar, which receives five canals and communicates with the hydrophore 
tube (sand canal). In short, the ambulacral system is regarded as an acces- 
sory to rt^spiration, to be employed when the Starfish, being uncovered by 
by the water, cannot employ its respiratory creca.
