was taken by the naturalists on board the " Knight Errant " 

 in 530 to 650 fathoms. 



Textularia tiirris, d'Orb. — Several dead specimens of this 

 species were obtained in Soundings Nos. 2, 3, and 6, new to 

 this locality. 



Bolivina heyrichi, var. alata, Seg. — Several dead specimens 

 were obtained from the material got from Station No. 4 and 

 Sounding No. 4, new to British waters. 



PolymoT'phina elegantissima, P. and G. — One specimen was 

 found in the material from Station No. 5. This interesting 

 species, according to Mr H. B. Brady, is confined to the Pacific 

 Ocean; it is therefore worthy of note to have found an 

 isolated specimen so far from its natural haunts. 



Glohigerina hulloides was taken by the surface nets often 

 outside the Diatomaceous zones, covered with their delicate 

 spines. 



Discorhina orlicularis and D. glohdaris are also of interest, 

 being fonnd off the Shetland Islands. 



The principal object of my accompanying the " Energy " 

 was to investigate the habits and food of the herring, and 

 whatever additional information I have obtained on this sub- 

 ject will present itself in the foregoing pages. The time 

 was so short, and the difficulties with which I had to contend 

 were such as to limit the information obtained. The most 

 important point brought out by my cruise in the " Energy " 

 is the necessity for continuous observations of a similar kind, 

 but under better conditions. It seems to me that extremely 

 valuable results would be obtained if a steam vessel, capable 

 of remaining at sea for a few days at a time, were available 

 for a purely scientific research on the natural history of the 

 herring and other food fishes, which should visit all the 

 principal fishing centres of Scotland. One season might be 

 spent on the east coast, another on the west, and so on for a 

 few seasons ; and in this way much, if not all, the information 

 so much sought for could be safely collected. 



Special attention should be drawn to the following points : — 

 (1.) The direction in which the herring are swimming when 

 caught, — which is easily ascertained by finding the exact posi- 

 tion in which the nets are lying ; (2.) Collecting the pelagic
