This species was " ver}^ rare " in Swan's collection from Neeah Bay. 

 It has not been found since except at Clayoquot Sound, where a few 

 specimens were obtained last year in shallow water by Dr. Newcombe.

 Rissoa castanea, Moller, Index Moll. Groenl., p. 9 (1842). 



Our four species of Alvania are found under stones, or at the bases 

 of sponges, at low water, but from their small size are easily overlooked. 



I have found the first three on many occasions at Victoria, Salt 

 Spring Island and Nanaimo. 



Dr. Dawson obtained a few specimens of compacta and reticulata at 

 the Queen Charlotte Islands, the former species at Dolomite Narrows, 

 and the latter in Yirago Sound. 



A. castanea is known from this province by a single specimen taken 

 by Dr. Newcombe, in Clayoquot Sound. This species seems to be inter- 

 mediate, as to sculpture, between A. filosa and A. reticulata.
