Oliva ispida Link, Marrat, Thes. Conch., IV, Oliva, 12, figs. 15, 

 16. 



Oliva fusiformis Lam., Ann. du Mus., XVI, p. 318, 1810. 



Oliva obesina Duel., Monogr., in Conip. Rendus, II, tab. 16, figs.

Both Bolten and Lamarck again refer to the same figure by Mar- 

 tini (Conch. Cab. II, tab. 51, f. 562) Lamarck's first reference is to 

 a similar figure in the Encyl. Meth., plate 367, fig. 7. The mark- 

 ings are coarser than in 0. reticularis. Specimens are frequently 

 obsoletely banded or overlayed with brown. 0. bullata Marr., seems 

 to be a narrow form of this species. 



Since my notes appeared in the October NAUTILUS my friend Mr. 

 Charles Hedley, of Sydney, Australia, has written that Oliva oliva 

 Linne should be used in place of Oliva vidua Bolton. In this I now 

 agree although at first I thought it was difficult to decide just what 

 form should bear Linne's name. Hanley says: " Still it is not un- 

 worthy of remark that the Oliva nigrita of Karsten (0. maura of 

 Sowerby, Genera Shells) has been indicated as the principal variety 

 or form in the ' Museum Ulricse ' and that all cited engravings (Ar- 

 genville alone excepted) of the tenth edition of the ' Systema ' 

 wherein the species originally appeared, pertain to that shell." 



Mr. Hedley also calls my attention to Oliva annulata Gmelin 

 (Syst. Nat., p. 3441, 1792) which I have entirely overlooked. This 

 replaces 0. amethystina Bolten. Both references Lister's Conch., 

 tab. 717, f. 1, and Martini, Conch. Cab., II, tab. 51, f. 567, refer 

 to the white form with a revolving ridge, 'f testa laevi alba dorsi an- 

 nulo carinato." It seems unfortunate that this pale, abnormal form 

 should become the typical, and the beautiful normal form the variety 

 amethystina. 



NOTES ON CALIFORNIA SHELLS. III. 



BY WILLIAM H. DALL. 



In a brief resum of notable things observed in the collections on 

 the California coast which I was privileged to visit last summer, it 

 is impracticable to mention all the collections visited, notwithstand- 

 ing nearly every one contained something of special interest, and 

 the courtesy and hospitality of the collectors was unfailing and
