CLASS VI. CIRRHOPODA.* 



THIS Class is interesting to the naturalist, as ex- 

 hibiting a structure which connects two very dis- 

 tinct great Divisions, so that it might, with al- 

 most equal propriety, be placed here or at the 

 commencement of the ensuing Division. 



While we find them covered with a stony shell, 

 composed of many pieces, and invested in a mantle 

 like the Mollusca, we see that they also have jointed 

 feet, a mouth furnished with jaws, and palpi , and 

 other internal organizations, which shew their affi- 

 nity with the Crustacea. The well-known genus 



Anatifa^ the Barnacle, 



shall be our illustration of this Class, notorious as 

 having been the subject of a most ridiculous opinion 

 already alluded to, that a species of Goose was, 

 in due course of nature, produced from its shell, 

 an absurdity which has unfortunately been seem- 

 ingly sanctioned by the scientific appellations given 

 to the species. The Barnacle is enclosed in a shell, 

 having some resemblance to that of a Mussel, but 

 formed of five distinct pieces, united by a tough
