42 THE NAUTILUS. 



arcnai-in L. is highly prized here as food, and grows six inches 

 long. Maehcera patula Dixou is sold in our markets. Pgammobia 

 rubroradiata Nutt. is more abundant and larger than in the south. 

 It is found 5 inches long, here, partially covered with dark brown 

 epidermis. Tapes and Saxidomus are well represented, and, though 

 not so prettily marked, are very much larger and stronger (coarser) 

 than those growing iu the warmer waters of the south. They are 

 almost always to be found in the markets. 



Zirphcea crispata L. was recently described in one of our Tacoma 

 daily papers by one of our Government surveyors as " a new clam." 



" We have found a new shell unknown to science," etc. We 

 were greatly amused, and sent an article to the paper the next day 

 saying Zirphcea crispata (" a new clam ") is found in abundance on 

 both sides of the Atlantic, and was named by Linnreus long ago. 



Limpets I have found in great abundance and of great size. I 

 have several specimens of Acmaa patina Esch. found here in the 

 "Narrows," measuring 2! inches iu length and 13 inches across. 

 Many of this species have bauds of translucent tints on their inte- 

 rior, and are beautifully marked outside. 



A.pelta\s regularly marked with stripes from the apex, which is 

 often corroded, in adult specimens, to the base. This is a most 

 pleasing shell ; is a sort of hermit, lives alone, often easily obtained ; 

 strong, not easily broken ; often pure white inside, sometimes banded. 

 I have one with a bright yellow baud inside, embossed. Large 

 specimens measure Id inches in length,!} inches wide, 11 inches 

 high. I have not found A. spectrum Nutt. nor Lottia gigantea Gray, 

 here. Fine specimens and many variations of A. wabra Nutt. are 

 abundant. I have found more of A. persona than of any other spe- 

 cies. At Brown's point, we find at one spot a variety having a 

 gray interior with beautiful translucent bands. This is a new var- 

 iation to me. A. asmi Midd. is found here, and many I have not 

 been able to classify. 



I have one specimen of Fissuridea aspera Esch. 21 inches long, 

 li inches wide and nearly 11 inches high. 



Limpets are sometimes used for picture frames by setting thrm 

 deep in wood and fastening with glue. I saw one valued at fifty 

 dollars here.
