COPEPODA COLLECTED IN MALTESE SEAS. 139 
hitherto unknown as occurring near the surface. Probably 
Dr. Bruce will find opportunity for some deep tow-netting 
about Malta during the present year. 
DESCRIPTION OF THE SPECIES COLLECTED. 
Family CALANIDA. 
Calanus finmarchicus, Gunner. 
C. valgus, Brady. 
C. propinguus, Brady. 
C. pavo, Dana. 
C. gracilis, Dana. 
All these species of Calanus were found in moderate 
quantity, and appear to be little affected by temperature. 
The elegant peacock-tail plumes, figured by Dana* as 
terminating the caudal appendages of C. pavo, were not 
present in any of the specimens obtained, although it is 
evident they had become detached, a fact I noted when 
describing the Copepoda of the Canary Islands. + 
Kucalanus attenwatus, Dana. 
Very large specimens of males and females occur 
sparingly. 
EL. setiger, Brady. 
E. mastigophorus, Claus. 
A few specimens only were found of each species. 
Hemicalanus longicornis, Claus. 
A considerable number of this striking species were 
found.
