ON THE LAMELLICORNS OF OLIVIER. 



171 



lamince consists of two very narrow strips at the base of the 

 others ; this is the case also, according to Blainville, in the 

 Osteodesma, allied to the former. Though it is not by the 

 action of the orifices or siphons, or by the relaxation of the 

 shell-muscles, and the opening of the valves, that the water 

 is drawn into the mantle, yet these accompany the occurrence; 

 and though the water commonly escapes in a continuous 

 stream from the action of the cilia, a sudden ejection of it 

 frequently takes place, accompanied by a closing of the valves 

 and a contraction of the siphons. These latter parts have 

 frequently at their extremities circles of ciliated fringed pro- 



cesses.
