A Si/nopsis of the Genera of Cirripedcs arranged in Natural 

 Famines, with a Description of some new Species. By John 

 Edward Gray, Esq. FGS.&c. ^

Barnacle and acorn shells first attracted the attention of 

 the older naturahsts on account of the fables that they were the 

 origin of the immense flocks of barnacle geese, as described by 

 Gerard and others, but they were afterwards studied zooiogi- 

 cally, 



Linnseus placed these animals together in a genus under the 

 name of Lepas, considering the animal as similar to his unfi- 

 gured, and at present unknown, genus Triton. 



Their anatomical structure has been displayed by John Hun- 

 ter, Sir E verard Home (Comp. Anat.), Poh (Test. des deux Siciles), 

 Cuvier (Ann. du Mus.), Savigny, Biainville (Anat. Comp.), and 

 others. 



The zoological characters of this group of animals have been 

 much studied by Bruguieres, Lamarck, Schumacher, Leach, and 

 Ranzani; but it has been peculiarly unfortunate in having been 

 chiefly attended to by naturalists who appear to disdain to 

 consult and quote the works of others, or even to use their' 

 names, as may be observed by the following chronological list 

 of genera, with the synonyma of the subsequent zoologists.

Lepas (for the whole), now abolished, as the ctlier namei 

 were used prior, and this means properly a Patella.
