92 THE NAUTILUS. 



Band 3 is the one most persistent, and even in the shells which I 

 have put down as 00000 yellow there is a very faint indication of it. 

 In many of the 35 this band shows as a distinct patch back of the 

 lip, with fragments at other places, while the balance of the band is 

 more or less transparent as in Var. arenicola. 



At Bar Harbor and on Bar Island, Frenchman's Bay, Mr. Hen- 

 derson and I collected a number of horlensis all of which are 00000, 

 and of a bright canary yellow. GEO. H. CLAPP.

 the NAUTILUS by my friend Mr. Maxwell Smith about the con- 

 chology of La Jolla, Cal., I send a list of a few species which were

 terest in this connection, as one species has not been found in Cali-
