MARSHALL: ADDITIONS TO ‘‘ BRITISH CONCHOLOGY.” 339 
T. caput-serpentis L.—The MacAndrew collection contains 
specimens from the British Channel, ‘‘a new locality if 
correct, but not astonishing, as it ranges from N. America 
to Japan” (Cooke). Not confirmed by the ‘‘Po:cupine” 
dredgings, though 7° cranium and T° septaza occurred there. 
Var. septentrionalis Couth—Corea, 35 fath. (H.M.S. 
“Sylvia ”) ! 
Terebratella spitzbergensis Dav. — Farce Channel 
(“ Triton”)! 
Argiope decollata Chem.—Scilly Islands, 40 f. (Burkill and 
J.T.M.) ; off Fermain Bay, Guernsey, 16 f. — 
A. cistellula S. Wood.—Shelly or gravelly ground, 12—95 f. 
Scilly, 40 f. (Burkill and J.T.M.); Lynn of Morven, 40 f. 
(Knight) !; Weymouth Bay (Damon)! ; Sound of Sleat, 30— 
go f.; Gairloch, 12—30 f.; Loch Boisdale, 2of.; Barra, 45 f. 
(Somerville and J.T.M.); Eddystone, 30 f. ; W. Orkneys, 45f. 
Jeffreys’ figure is useless except as an outline, and that 
varies considerably ; but his generic figures are very good. 
The figure in Sowerby’s “Index” is a good one, but the 
dimensions are double what they should be. The A. sem- 
tnulum of the latter work is an A. ciste//ula with the beak 
abnormally produced. 
Gwynia capsula Jeff.—-Low water to 25 fathoms. Iona, 20 f. 
(Somerville and J.T.M.) ; various parts of Jersey at extreme 
low water (Duprey and J.T.M.). In the latter locality they 
live under large embedded stones, the larger the stone the 
better the yield. Sometimes these stones are so deeply sunk 
in the sand as to require a lever to raise them. ‘The speci- 
mens are at first very difficult to detect on account of their 
minute size and the sandy condition of the stone ; but the 
best way to detect them is to turn a likely stone to the sun- 
light, and dash a handful of water over it. ‘This will clear 
the stone of sand and grit, and show up the Gwynza. The 
Jersey specimens, minute as they are, are giants compared
