a Comprising both the "Gephyrea armata" and the Sipunculoidea. 

 b Some of the species comprised in the Trieste list are not marine. 

 ' Seventy of the Plymouth gastropods are nudibranchs. 



Before leaving this hasty comparison between our own biological census and a few 

 of the similar undertakings elsewhere, reference should be made to certain works in 

 which some features of our own survey are closely paralleled. We must mention first 

 of all the explorations in the Kattegat of the Danish steamer Hauchs, under the charge of 

 C. G. J. Petersen. The resemblance between the Danish project and our own lies in the 

 successful endeavor to correlate the distribution of various species with peculiarities 

 of bottom and of water temperature, and particularly in the presentation of a number
