Not in Dr. Dawson's collection, but a large male was dredged in the 

 Gulf of Georgia by Mr. J. Kichardson in 1875.

A single dry and broken specimen from Vancouver Island. 

 Nectocrangon lar Brandt (ex Owen). 



Two males and three females from Vancouver Island. 



The specimens are all dry and in rather bad condition for a careful 

 comparison, but they all differ considerably from any Atlantic speci- 

 mens which I have seen. In the 823ecimens from Vancouver, the 

 rostrum and the spines of the dorsal carina of the carapax are longer 

 and more slender than in specimens from off Nova Scotia and from the 

 Gulf of St. Lawrence. In the Vancouver specimens, the dorsal carina 

 on the third, fourth and fifth segments of the abdomen is broad and 

 rounded, or flattened, and scarcely reaches the posterior edges of the 

 segments, and the two carinas upon the sixth segment are rounded and 

 fade out in the same way before reaching the posterior extremity of 

 the segment ; while in the Atlantic specimens referred to, the carina 

 upon the third, fourth and fifth segments is acute, and on the fifth 

 segment projects from the jtosterior margin in a more or less conspic- 

 uous triangular tooth, and the carinse on the sixth segment are acute 

 and continue to or a little over the posterior extremity of the segment. 

 These differences may possibly indicate distinct geographical species.
