Liothyrina wyvillii Davipson. 
Terebratula wyvillii Davidson, Challenger Report, 1880, Zool., 1, p. 27, pl. 2, figs. 7-9. 
‘Challenger ” station 299, off Valparaiso, in 2160 fathoms, bottom temperature 
(34° F.) 1°.1 C., and station 302, off the coast of Patagonia, in 1450 fathoms, 
temperature 1°.5 C. Also at various other localities in from 1035 to 2900 
fathoms, and from latitude 42° 43’ south to 35° 22’ north. 
U.S. 8. “ Albatross,” station 4709, southwest of the Galapagos Islands, in 
2035 fathoms, ooze, attached to manganese nodules, bottom temperature 35°.3 F. 
U.S. N. Mus. 110,745. 
Several specimens, mostly broken by the nodules in the trawl net, were 
obtained. The brachia are small compared with those of the shallow-water 
species, but a small spiral median lobe and two lateral loops were found to be 
present.

Mission to Cape Horn, various localities in the Patagonian and Fuegian region 
in 8 to 120 fathoms, temperatures 6°.2 to 8°.2 C. (42°.7-46°.7 F.). 
This is really a species of moderate depths, but occasionally lives at a depth 
exceeding 100 fathoms.

“Challenger” station 299, off Valparaiso, in 2160 fathoms, ooze, bottom tem- 
perature 1°.1 C. (84° F.). 
Ouly a single defective specimen was obtained, notable for its extremely thin 
and fragile shell.
