OP CONCHOLOGY. 



Cuming having collected at two islands of the same name (Lord 

 Hood's Island), one in the Gallapagos group and the other at 

 the Paumotus. 



Lord Hood, when a young man, accompanied Captain Cook 

 on his third voyage as midshipman. Subsequently three islands 

 were named after him. The one at the Gallapagos may retain 

 his name ; that in the Paumotus should be designated by its 

 proper native name, " Maurukea," and also the one at the 

 Marquesas, "Fatu-Haku." 



Nassa tiarula, Kien. 



A large and beautiful collection of shells, dredged the past 

 year by a gentleman on the West Coast of Mexico, which I have 

 had opportunity of looking over, contained a number of specimens 

 of the above species, which leave no doubt but that it is a variety 

 of iV". tegula, Rve, having light colored specimens in my collection, 

 from La Paz, which closely connect it. The original locality, by 

 Kiener, copied by Reeve, "Madagascar," is probably an error. 



Latirus nodatus, Martyn. 



The above should also be struck out of the West Coast fauna. 

 The locality given to it originally by Martyn, "New Holland," 

 should probably have been " South Seas." " Li Voy. Blossom it 

 is properly credited to the Pacific. 



Mr. Reeve, however, in Con. Icon., gives "Panama" (Cuming) 

 as its locality, which has consequently been adopted by several 

 authors. Not one of the numerous collectors that have visited 

 that locality since, so far as I can ascertain, have confirmed it. 



It occurs very rarely at the Hawaiian Islands, and I have 

 received it from Southern and Western Polynesia.
