50 THE NAUTILUS. 



in Binney's Gould, no action has been taken. A comparison 

 of the figures shows at once that the two forms are distinct. 

 For the New England shell I propose the name of Margarites 

 Johnsoni, in honor of Mr. Chas. W. Johnson, author of the 

 valuable "List of New England Mollusca." Specimens have 

 been collected by the Canadian Neptune Expedition at Port Bur- 

 well, Ungava, Hudson Bay. 



Cypraea pacifica was described by J. M. Ostergaard in THE 

 NAUTILUS for January, 1920, p. 92, and well illustrated. I have 

 had the opportunity of comparing a specimen with the varieties 

 of C. helvola from the dump at Honolulu, to which it bears a 

 suspicious resemblance, though apparently very distinct, but 

 the bleaching of the specimens from this dredged material plays 

 strange tricks with the Cypraeas. However the name is long 

 preoccupied by Gray, in the Conchological Illustrations p. 15, 

 pi. 7, fig. 39*, 1832. I would suggest that this interesting form, 

 whether variety or good species be named ostergaardi after its 

 discoverer.

BERGH'S description of various species of Melibe (1875, 

 Melibe capucina, M. rangti; 1880, M. vexillifera; 1884, M. 

 papillosa; 1888, 1890, M. ocellata; 1902, M. bucephala; and 

 1907, M. rosa Rang), emphasizes the following as Melibean 

 characteristics : ' ' Bulbus pharyngeus cum mandibulis ut i/ti 

 Phylliroides; margo mastica-torius mandibulis fortiter denta- 

 tus; ' (1875) p. 362. Perhaps the only exception to this 

 may be found in the species collected at the mouth of the 

 Columbia River, in the State of Washington (1904), irj| 

 which case, the author is not sure of the mandibles. He says : 

 " Bulbus pharyngeus lingua destitutus. Die Mundrohre und 

 der Schlundkopf scheinen sich wie sonst bei den Meliben zu
