QUEEN CHARLOTTE ISLANDS. 95 B 



below are much decayed. An elevation of the coast to the extent of 

 at least fifteen feet since the country became inhabited appears to be 

 indicated by this deposit. 



Specimens collected in the lower layers include, according to Mr. S V^| from 

 J. F. Whiteaves, the following species : — 



Saxidomus squalidus, Desh. 



Tapes staminea, Conrad. 



Macoma, sp. 



JSTassa mendica, Gould. 



Cryptobranchia co?icentrica, Midd. (Lepeta cmcoides, Cpr.) 



Tornatina eximia, Baircl. 



Littorina Sitchana, Phil. 

 And other small gasteropods. 

 In the highest layer the following species were found to occur : — 



Saxidomus squalidus, Desh. 

 Tapes staminea, Conrad. 

 Cardium Nuttalli, Conrad. 

 Purpura crispata, Chemn. 



On the Ma-min Eiver, at the head of Masset Inlet, about a mile and Raised Wctes 

 a half up the stream and some feet above the present level of high River! m 

 tide, a deposit similar to that just described forms the bed of the stream, 

 and rises in a bank from six to ten feet above it. The following species 

 of shells resembling those of the last locality were found here. Many 

 of them are imbedded with the valves united, and in some cases the 

 ligature at the hinge has been preserved. 



Macoma nasuta, Conrad. 

 Saxidomus squalidus, Desh. 

 Tapes staminea, Conrad. 

 Lucina filosa, Stimpson. 



In two places the burrows of lithodomous molluscs were observed in other evid- 

 rocks above the present water-line. One of these is in the bay on thetiorf. 

 east side of North Island, where a dark calcareous shale is affected in 

 this way just above the high-water mark. The second is on one of the 

 Bolkus Islands, in Skincuttle Channel, in an earthy dolomitic limestone 

 eight or ten feet above the tide. 



The flat land forming the north-eastern portion of Graham Island may 

 be regarded broadly as a terrace, proving the former presence of the 

 sea at a level two or three hundred feet above the present, but this must 

 have been while the glacial conditions still endured. A terrace of much 

 more recent origin was seen in several places in Skidegate Inlet, and 

 where measured in one locality was found to stand twenty-six feet
