tThe place of the original descriptions of Bulla rubiginosa Gould, and Bulla 

 diaphana Couthouy, is given by Gould in his report upon the Mollusca of the U. S. 

 Exploring Expedition as Proc. Boston Soc. Natural History, III, 1849, pp. 107 and 91 

 respectively. This has been cited in several recent works, e. g. by Pilsbry in Tryon's 

 Conchology, XVI, pp. 330 and 356. I am unable to find any such description in any 

 of the earlier volumes of the Proceeding'^, nor any earlier descriptions than the ones 

 indicated above.
