ZOOLOGY. 



REPORT on the Pennatulida dredged by H.M.S. Challenger during the years 

 1873-1876. By Professor Albert v. Kolliker, F.M.R.S., &c., &c. 



In accordance -with the, request of Sir Wyville Thomson, I undertook the description of 

 the Pennatulida collected by the Challenger Expedition. With the exception of 

 Urribellula thmnsoni, the whole coUection came into my hands in April 1879. I devoted 

 the whole of the succeeding summer to the investigation, and sent my MSS., with a 

 number of plates drawn by Mr Rabus of Wlirzburg, to Sir Wyville Thomson in the begin- 

 ning of August of the same year. 



Want of time, and the nature of the material forwarded to me, prevented me from 

 going deeply into anatomical details,. and there was, perhaps, the less reason for my doing 

 so, as my monograph of the Pennatulida (Auatomisch-systematische Beschreibung der 

 Alcyonarien, Frankfurt, 1872) gives to those who have a special interest in this department 

 an opportunity of gaining a clear insight into the structure of the group. 



The following is a description of all the Challenger Pennatulida according to the 

 classification given at the end of this paper : — 



Order PENNATULIDA.
