THE NAUTILUS. 67 



Calliostoma supragranosum Cpr. Detected in kelp holdfasts. 



Cyanoplax hartwegii. Perhaps our commonest chiton, on 

 rocks near high-water mark, strangely omitted from Smith's list. 



Columbella fuscata. One specimen was found living years ago, 

 but no doubt estray from southern waters as well as a single 

 well-developed living specimen. 



Thais b'iserialis, not rare. Saxicava arctica. 



Corbula luteola, not rare. Saxidomus nuttallii. 

 Crepidula rugosa norrisianum. Terebratella transversa. 



Crepidula ungui/ormis. Thracia curta. 



Crepidula dorsata. Thracia squamosa. 



Hipponyx antiquatus. Transennella tantilla. 



Hipponyx cranioides. Turbonilla castanella. 



Hipponyx tumens. Odostomia aequisadpta. 



Kellia laperousii. Venerupis lamellifera. 



Kellia suborbicularis. Mactra cali/ornica. 



Modiola capax. Mactra falcata. 



Mytilimeria nuttallii. Mactra nasuta. 



Pecten latiauritus. Mactra planulata. 



Psammobia californica. Phacoides nuttallii. 



The above are some of the shells omitted from the lists re- 

 ferred to that I have noted on the beach, quite a number of 

 them in kelp holdfasts washed ashore. 



A considerable number of minute shells yet undetermined 

 will add considerably to the list, besides several chitons and 

 larger shells that are being studied.
