[TAYLOR] MARINE MOLLUSCA Al 
Gould’s type was from Santa Barbara, and Dr. Cooper dredged the 
species in that neighbourhood in 12 to 20 fathoms. As stated above our 
specimens have all been taken between tides.

This shell is quite as common as the last named, but as it inhabits 
deep water it can only be obtained by dredging. It has been found in 
nearly all the localities in which collections have been made, Dr. New- 
combe speaks of finding it at extreme low water; Dr. Dawson, on the 
other hand, dredged it at a depth of 111 fathoms. Its usual station 
seems to be in clean sand in 10 to 30 fathoms in company with Mesalia 
reticulata, Cryptodon sericatus, ete. The absence of the purple stain 
readily distinguishes this species from P. tantilla, which is moreover a 
much smaller shell.

Generally distributed, but not common, It has been dredged by 
Dr. Dawson in Quatsino Sound and at the Queen Charlotte Islands ; by 
Dr. Newcombe at Comox, Clayoquot, etc.; by myself at Departure Bay 
and Victoria. The young shells are generally coated with sand, like 
Lyonsia and some other species.

Very common between tides, generally among stones on muddy 
shores. This species varies much in shape and sculpture. Sometimes it 
is found in the burrows of Penitella penita and is distorted after the 
manner of Petricola. The colour is also variable, the common variety 
being white, but some specimens are almost as brightly coloured as the 
Californian Tapes grata. An extreme variety is dark chocolate colour, 
Tapes staminea is a common article of food.
