Society's Journal. Ehlers, however, has, I think, satisfactorily shown that this 

 family is more nearly connected with the Aniphinomacea ; and as he has care- 

 fully worked out the family and genera which appertain to it, I propose fol- 

 lowing his arrangement, and bringing now the family Palmyrida^ into the 

 group of Amphinomaccre. 



* These branchia?, composed of flat bristles, or palecs, as they have been 

 called, are considered by Savigny, in the case of Palmyra, to be the setiB of the 

 dorsal row of feet. He placed the genus amongst the Apln-oditacea, and in 

 this arrangement he has been followed by Audouin and M.-Edwards, Grube, &c.. 

 who all take the same view of the case with regard fo tliose appendages.
