five inches. In this fragment there is no trace of any emargination 

 of the inner surface of the volution, so that the outer whorls of large

North shore of Cumshewa Inlet, eighteen specimens and some frag- 

 ments : also Skidgato Inlet, one specimen from each of the following 

 localities, viz., Shingle Bay; east side of Shingle Point; Shore one 

 mile and three quarters south-west of Welcome Point ; and Bay east of 

 Alliford Bay. 



The largest specimen yet collected at the Queen Charlotte Islands is 

 six inches in its greatest diameter. The reason for regarding A. 

 filicinctus as a mere synonym of A. Sacya, Forbes, will be found stated 

 in a foot note to page 104 of the present volume, and this conclusion 

 is fully sustained by the much larger and in some respects better 

 series of specimens since collected by Dr. CT. M. Dawson.
