to Mhieh (iould's name, caurina, more strictly applies. The shore variety 

 sometimes attains a very large size, one mentioned by Dall measuring 

 58 X 50 X '^1 nim. I have specimens from Salt S|)ring Island and 

 ])i'))arture Bay nearly as large.

This is not a common shell in any locality. Dall quotes its range as 

 from Port Etches to Catalina Island, California, and remarks that it is 

 everywhere rare, owing to its deep-water habitat. It is sometimes, how- 

 ever, found in comparatively shallow water, as at Victoria, where Mr. 

 Richardson, Dr. Newcombe and myself have all dredged it. It has also 

 been taken within the province by Dr. DaAvson, in Discovery Passage 

 and Johnston Strait and at the Queen Charlotte Islands. 



British Columbian specimens are said to be smaller than Californian 

 ones, and have received from Dr. Davidson, in his latest work,' the 

 varietal name of Vancouverensis.

The only specimen that I have heard of as having been taken in 

 British Columbia is the single dead shell obtained by Mr. J. Eichardson 

 at Victoria in 1875.

This is a common and well-known circumpolar shell, which on the 

 west American coasts seems to reach its soutliern limit at the Straits of 

 Euca. 



Though not so abundant in British Columbia as T. transversa or 

 T. ungidcula, it has been met with at Victoria bj'^ Mr. Richardson. Dr. 

 Newcouibe and myself, and at Discovery Passage and .lohnston Strait
