remains of the egg-sacs and others free in the gathering. 

 Other swarms, consisting almost entirely of males, were 

 found 15 miles S.W. from Morecambe Bay Lightship, 

 February 26th, and 10 miles E. of Point Lynus, 

 March 6th. 



Copepoda. — The species most constantly present 

 throughout our district appear to be Calanus 

 finmarchicus , Pseudocalanus elongatus and Acartia 

 clausi. Of these the most constant in point of numbers 

 is Pseudocalanus. These three species occur in most of 

 our hauls, being more abundant in summer. In Cardigan 

 Bay and Carnarvon Bay the most abundant form during 

 the summer was Temora longicornis. Oithona similis 

 was rare in this part of the district, but was more 

 common in the northern part, where it occurred more 

 constantly than Temora, though never in as large 

 numbers. Centropages hamatus was taken in Cardigan 

 Bay and Carnarvon Bay in fair quantity during the 

 summer; C. typicus also occurred, though much less 

 commonly. Neither of these was found in any of our 

 hauls further north. Anomalocera •patter soni occurred 

 in various localities, both north and south, from June 

 onwards, but was always scarce. Isias clavipes and 

 Candacia, armata were taken in Carnarvon and Cardigan 

 Bays during the summer, the former being sometimes 

 fairly common, the latter always rare. 



Etjphattsiacea*. — Nyctiphanes coucliii was taken on 

 two or three occasions, in Red Wharf Bay and Carnarvon 

 Bay; it seems not uncommon in this part of the district. 

 A fair number of Euphausid larvae, in various stages, 

 were found in Carnarvon Bay from July until September, 

 and are probably referable to this species. Mega- 



* I have to thank Dr. W. M. Tattersall for much kind help in 

 connection with the Euphausiacea and Mysidacea.
