THE NAUTILUS. 99 



SOME MARINE MOLLUSCAN SHELLS OF BEAUFORT AND VICINITY. 

 By Arthur P. Jacot (Jour, of the Elisha Mitchell Soc., Feb., 

 1921, pp. 129-145, pis. 11-13). This has been a favorite col- 

 lecting place since the days of Dr. Stimpson, who published a 

 paper " Mollusca of Beaufort, N. C.," in 1860. Being the 

 meeting ground of a northern and southern fauna, it is an inter- 

 esting locality to study distribution. The fauna is also divided 

 by two marked local conditions those frequenting the ocean or 

 outer beach and those of the sounds or quiet waters. The 

 Pteria eximia Reeve, referred to, may represent only the young 

 or a variation of P. colymbus. Panopea floridana Heilp. = P. 

 bitruncata Conr. , the type locality of the latter was Fort Macon, 

 N. C. The epecies figured as Alectrion ambigiia Montg. is A. 

 acuta Say. One new species Odostomia (Menestho*) beauforti is 

 described. C. W. J. 



NOTES. 



In the Proceedings of the Malacological Society of London, 

 volume 14, page 202, 1921, just at hand, I find a statement by 

 Iredale in which he says that the name Syncera Gray, 1821, is 

 a nomen nudum, and therefore unavailable in the " connexion " 

 used in my paper " The West American Mollusks of the fami- 

 lies Rissoellidae and Synceratidae and the Rissoid genus Bar- 

 leeia." 



If this be true, then my understanding of a nomen nudum 

 must be at fault. In order that there may be no misunder- 

 standing in the matter I quote from Gray's paper " A Natural 

 Arrangement of Mollusca, according to their Internal Struc- 

 ture," by Mr. John Edward Gray, in ''The London Medical 

 Repository, Monthly Journal and Review," volume XV, page 

 238, 1821. 



" Nerita Syncera Hepatica, N. S. The animal of this shell 

 differs from all the others of this order, by the eyes appearing 

 to be at the ends of the tentacula; but, I believe, that they are 

 placed on a peduncle, as long as the tentacula, and the peduncle 

 and tentacula are soldered together. ' '
