Several specimens of a small copepod, taken by the writer in a towing net 

 in the Gulf of St. Lawrence, in 1873, were identified with this species by 

 Professor S. I. Smith. 



Ohher sppcimens of a copepod, taken by the writer in a towing net, near 

 the Magdalen Islands and at other localities in the Gulf of St. Lawrence, 

 have been supposed to be referable to the Calaniis Finmarchicus of Gunner, 

 of which the Cetocheilus septentrionalis, Baird, is a synonym. 



OSTRACODA. 



The following species, dredged in the Gulf of St. Lawrence by Sir J. W. 

 Dawson, the writer, and others, up to 1869, were identified by Mr. G. S. 

 Brady, and recorded by him in the Annals and Magazine of Natural 

 History for December, 1870, and in the fifth volume of the Second Series of 

 the " Canadian Naturalist."

The writer's subsequent dredgings in 1871-72-7''. added many more 

 specimens of the foregoing, and the following additional species, as identified 

 subsequently by Mx-. Brady and Mr. David Robertson.

Of these, Cythere Dawsoni, Cytheridea papillosa, C. punctillata, C. Sorby- 

 ana, and Eucythere Argus, have also been found fossil in the Leda clay of 

 Montreal. 



The types of the recent Cypridina excisa, Stimpson, are from Grand 

 Manan, among nullipores in 4 or 5 fathoms, and specimens that are supposed 

 to be referable to this species have been dredged in the Gulf of St. Lawrence 

 by the writer, and on the Labrador coast by Packard.
