212 PANDORID^. 



raiiean examples we have observed vivid orange specks 

 around the orifices of the tubes.] The foot is of a white 

 colour, flat, and tongue-shaped. " There is only one 

 branchial lamina at each side, having a furrow at its 

 uppermost margin, and a very fine rather indented line 

 above it, which may be the termination of each trans- 

 verse thread of the branchial leaf, or possibly the rudiment 

 of an upper branchial plate, which certainly is wanting in 

 this species ; at the anterior end on each side there are 

 two small triangular rather rigid labial appendages, each 

 united with the other by a small membrane around the 

 mouth. They are of precisely equal size, lying one on 

 the other, both (on each side) plain on their outer surfaces, 

 and strongly pectinated on the inner ; the labia are so pre- 

 cisely of a size, and cover each other so exactly, that they 

 may be mistaken for a single labium on each side."" 



It is frequently obtained alive by dredging on many 

 parts of our coast in the west and south, usually on muddy 

 ground. Off Portland (S. H.); in twenty-seven fathoms 

 water, eight miles oft' Dartmouth (M'Andrew and E. F.); 

 at Exmouth (Clark); Torbay (S. H.); Cornwall, in seven 

 fathoms, Weymouth (M'Andrew and E. F.) ; Isle of Man 

 (E. F.) ; Anglesea, in twelve fathoms (M'Andrew) ; 

 Guernsey (S. H.) 



In Ireland it is very rare, specimens have, however, 

 been "dredged off Carrickfergus, Sept. 1835 (Mr. Hynd- 

 man); subsequently by Mr. H. and myself in Strangford 

 Lough" (W. T. Ann. Nat. H., vol. v. p. 14); in sixty 

 fathoms off" Cape Clear (M'Andrew); in twenty to twenty- 

 five fathoms, Skye, and in ninety fathoms off the south 

 coast of Mull (M'Andrew and E. F.); "Oban, Loch 

 Shieldaig, Hebrides'" (Jeffreys) ; Loch Fyne (Barlee). 



It ranges to the Mediterranean.
