minute description in order to ascertain the different species with 

 any degree of precision. In most instances where they possess 

 conspicuous lateral cirri, their shape will be found greatly to as- 

 sist in discrimination. 



Our reference to Gmelin for this species, it must be confessed, 

 is not without very considerable doubt, especially as he has 

 quoted a figure in Easier not in the smallest degree like, nor is it 

 even of this genus. But possibly our species may be the same 

 as that described by Pennant. 



Ampiiitrite iNFUNDIBULUxM. 



Tab. VIII. 



Body long ; joints numerous, distant, of an orange colour an- 

 nulated with whitish: fasciculi very small; branchiae obscure : 

 at the base of the tentacula a scalloped membrane: tentacula 

 two, semicircular when spread, and nearly uniting into a regular 

 circle ; these are each composed of about thirty-seven rays, con- 

 nected by a transparent web, except at the points, which turn a 

 little inwards ; the outside of these singularly beautiful arms is 

 smooth, and of a purple colour, darkest at the tips of the rays; 

 the inside is most elegantly ciliated with two rows of fimbriae 

 along each ray, of a chesnut colour shaded to a purple near the 

 centre : mouth purple, the lips bordered with chesnut. 



This animal is capable of the most sudden contraction, from 

 eight or ten inches in length, to three or four; it has between a 

 hundred and fifty and a hundred and sixty joints, becoming very 

 small at the posterior end. 



The case or tube formed by this species of Amphitrite is 

 wholly gelatinous, of a very firm and elastic nature, greenish 

 on the outside, but usually stained black by the soil they in- 

 habit. These cases arc composed of many layers or strata, and
