Vol. III. includes an important and elaborately illustrated 

 Report by Prof. A. Agassiz on the Echinoidea, and another by 

 Dr. P. Hoeck on the Pycnogonida, of which a fine series was 

 obtained during tbe voyage, thirty-three out of thirty-six species

 on the Anatomy of the Petrels, Prof. Haeckel's Report on the 

 Deep Sea Medusa, and the first portion of Dr. Theel's Report on 

 the Ilolothuroidea. 



Vol. V. contains a Report on the Ophiuridea by Theodore 

 Lyman, and another by Dr. Cunningham on the anatomy of 

 Thylacinm cynoceplialus, Phala/ngista maculata, and Phascogale 

 calura, based on specimens collected by the expedition.

 scientific account of the Actiniaria ; while an equally elaborate 

 Report on the Tunicata {Ascidice simplices) is furnished by Prof. 

 Herdman.
