THE NAUTILUS. 89 



ISAAC LEA DEPARTMENT. 



[Conducted in the interest of the Isaac Lea Conchological Chapter of the Agassiz Associa- 

 tion by its General Secretary, Mrs. M. Burton Williamson.] 



A number of good reports have been promised. The volume of 

 Transactions has been forwarded by Mrs. Mary P. Olney to Mrs. 

 Drake, who will forward it to Mrs. King at Napa, Gala. By that 

 time all our members will have received it. 



In the November NAUTILUS Mr. Herbert Lowe's name appeared 

 as "Howe" in the article on "Collecting During the Summer of 

 '96." 



The following nominations have been made for the officers of the 

 Chapter for 1898: for President, Prof. Josiah Keep; for General 

 Secretary, Dr. Wm. S. Strode. 



Dr. William Healey Dall has named a new shell collected in 

 Alaskan waters Crenella Leuna, in honor of Dr. Isaac Lea, for 

 whom our Chapter was named. The shell, a little bivalve, is de- 

 scribed in a Bulletin issued by the Natural History Society of 

 British Columbia, entitled "Notice of Some New or Interesting Spe- 

 cies of Shells from British Columbia and the Adjacent Region," by 

 William Healey Dall, Hon. Curator Dept, of Mollusks, U. S. 

 National Museum. The Bulletin contains 18 pages, 2 plates, with 

 38 figures, and an index to all species mentioned in the text. Of 

 the 30 species figured in this pamphlet, 27 are Dr. DalPs species, 

 23 are new species and 4 have been described by him but not fig- 

 ured in THE NAUTILUS. Leda taphria Dall, known on the West 

 Coast as L. ccelata Hinds (non Conrad) is figured. The October 

 NAUTILUS for 1896, contains a note on this species. The genus 

 Malletia is for " the first time recorded from the northwest coast of 

 America." 



MORNING TIDES. 



[From the report of Mrs. M. L- Beck. From the Transactions of the Isaac Chapter 

 for 1896]. 



One bright day in June I was told we were to go collecting the 

 next day at San Pedro, and as the tide would be low at half past 

 three in the morning, we would have to go to the beach the evening 

 before and stay all night at the cabin on the island. * AVe
