too, in fine style. The valves of the largest were 

 gaping to the extent of threte quarters of an 

 inch ; but the intermediate space was filled up 

 by the spongy-looking, fleshy mantle, of a semi- 

 pellucid orange hue. At one end protruded the 

 siphons, two thick, short tubes, soldered, as it

 shaggy fringe of cirri, or tentacles. The circular 

 orifices of these tubes — small holes, perfectly

 of the valves. The discharging orifices, however, 

 were but rarely visible, being usually closed, while 

 the others remained constantly open. But these 

 things were what we afterwards saw. For some 

 time we could look at nothing but the magnificent 

 foot, and the curious manner in which it was used.

 tongue, nearly cylindrical, but a little flattened 

 and tapering to a point. Its surface is smooth,
