Linyula. Living specimens havo been observed repeatedly by Dr. Carl 
Semper ; the arms are never stretched out, or even protruded beyond the 
shell ; the valves are generally moved in a somewhat lateral direction when 
the shell is to be opened, and this movement is rather slow. The propulsion 
of the blood within the vessels by vibrating cilia, and the absence of a 
heart proper, is repeatedly stated. Zeitschr. f. wissensch. Zool. xiv. 1864,

description of the organs of circulation, by the same author, ibid. vol. xi.
