In addition, the following are recorded in the note-books : — Globigerina, Pulvinulina 
micheliniana, Physalia, Velella, Diphyes , Sagitta, Saphirina and other Copepods, 
JJyperia, larvae of Squilla, Euphausia; and Calcarella spinosa for the first time. 
Willemoes-Suhm writes : “ Calcarella spinosa having been taken on the surface, 
it could be ascertained that it is indeed a Heteropod allied to the Atlantidse. Some 
doubts seem to exist about it, for Adams places it among the Heteropods, though very 
little known, while Keferstein mentions neither Calcarella nor Macgillivraya in Bronn’s 
Klassen und Ordnungen des Thierreichs. These Molluscs seem to be peculiar to the 
South Sea ; Murray says he has met with them several times.”
