Part III. — Seventh Annual Report 



often very numerous, and ranged on each side of § inch. In the earlier 

 part of the month some were ripe, others nearly so. Stomoh^achium octo- 

 costatum was likewise occasionally met with in considerable numbers, and 

 of good size. None were mature. Various specimens of Tima baircUi 

 made their appearance at and below 1\ inch. Many ova apparently 

 connected with this group were also captured, so that the food of the 

 minuter forms would thereby be increased. 



The Ctenophores were represented by myriads of Pleurobracliiai 

 throughout the entire month, their size ranging from y 3 g-t° § inch. None 

 were mature. Beroe occurred in smaller numbers, but was present in 

 most of the hauls, the average size of the specimens being from 1J to 

 2J inches. 



The bottom-nets presented Pleurobraehice, of varying size, ova and 

 larval forms of the same species. Moreover, they were in limited 

 numbers. It is possible some larval forms belonging to other Cteno- 

 phores were present. 



Echinoderms. — A great change had now ensued in regard to this group, 

 for only a few larval Pleutei appeared in the surface-net in the middle of 

 the month. 



Throughout October the larval annelids still abounded in the bottom- 

 nets, showing how ample the food-supplies of the smaller fishes are 

 from this group for a considerable period of the year. The forms chiefly 

 consisted of larvae of Nerine, and Polydora, larvae and young of Potynoe 

 and others. Sarjittce were obtained sparingly in this net in the earlier part 

 of the month, but at the end they were very numerous, and ranged from 

 8 to 15 mm. 



In the mid-water net Tomopteris occurred occasionally in small numbers. 

 Some reached the length of 1 J inch, others being much less. Very few 

 Sagittaa appeared in this net, and only on one occasion. 



In the surface-net the larval stages of Nerine and Polydora appeared 

 during the first half of the month, occasionally with a few small examples 

 of Tomopteris. Their numbers were, however, comparatively few, and in 

 contrast with the months immediately preceding. 



The bottom-nets still teemed with minute crustaceans from the 

 beginning to the end of October. The Copepods were represented by 

 swarms of Halitemora longicornis and Acartia longiremis, while Calanus 

 finmarchicus, Longipedia coronata, and Pseudocalanus elongatus occurred in 

 smaller numbers. Evadne nordmanni was frequent, but only occasionally 

 in large numbers. Nauplii were still plentiful, and in most collections a 

 few examples of the Cypris-st&ge of Cirripedes occurred, while the exuviae 

 of the adults were common. Other forms met with were, Diastylis ratlikii 

 and Atylus swammerdamii. The paucity of larval Decapods was a note- 

 worthy feature, but the smaller fishes had an ample margin in the other 

 groups. 



The mid-water net yielded comparatively few representatives of the 

 group. Young crabs in the pelagic condition were frequent; a few 



Cali'/i, Atylus swammerdamii, and a single Idotea linearis completed 

 the list. 



The surface-net exhibited a few Nauplii, which were most abundant on 

 the 1 7th. The Copepods were represented by many examples of Halitemora 

 Jongicomis and Acartia longiremis, and by the following in small 

 numbers, viz., Pseudocalanus elongatus and Oithona spinifrons. A few 

 specimens of Evadne nordmanni and of the Cypris-st&gQ of Cirripedes 

 occurred in most of the hauls. 



The Molluscoida during October consisted of many examples of 

 Cyphonautes.
