p. 711 «It (i. e. the central canal of each cirrhus) was supposed by 

 Prof. J. Müller, who first noticed its presence, to be occupied by a 

 nutrient vessel, proceeding from an organ contained in the basin-shaped 

 cavity of the (Ventrodorsal plate, which he designated as a heart.« 



These passages were quoted by Dr. Carpenter in an addendum 

 to a translation of Prof. Semper's »Kurze anatomische Bemerkungen 

 über Coniatulm which appeared in the Annals and Magazine of Natural 

 History for September 1875. 



Prof. Greeff was presumably acquainted with this »addendum«, 

 for in January 1876 he referred to Dr. C arpenter's'views respecting 

 the nervous system of Comatula which were first clearly stated therein, 

 although they were indicated in 1865 on p. 705 of the »Researches«. 



I think therefore that it will no longer be doubted that Ludwig 

 was right in describing Dr. Carpenter as having been the first to 

 make known the five-chambered nature of the so called »heart« of Co- 

 matula ; and that Prof. Gree f f 's claim to priority for this observation 

 will not bear examination. 



One thing more; Prof. Greeff has done me the honour of com- 

 mencing his last paper with a »Litteraturverzeichnis« that professes to 

 be »genau entnommen« from a paper of my own, which Prof. Greeff 

 quotes as follows — 



»On the arms of Antedon rosaceus. Journal of Anatomy and Phy- 

 siology. Vol. X. April 1877.« 



A more correct reference would have been : 



»Remarks on the Anatomy of the Arms of the Crinoids. Journal 

 of Anatomy and Physiology. Vol. XI. October 1876« and the copy of 

 the »Litteraturverzeichnis« would have been considerably more »genau« 

 if the last two references had not been printed — 



»8. R. Greeff, Ueber das Herz der Crinoideen. Sitzungsberichte 

 d. Ges. z.Bef. d.ges.Naturw. zu Marburg. No 13. Jan. 28. 1876. p. 88.«
