DALL: MOLLUSCA AND BRACHIOPODA. 443 
LIOTHYRINA OEHLERT. 
Liothyrina uva Bropverre. 
This species was originally described from shallow water, 8 to 12 fathoms, off 
the west coast uf Mexico, near the Isthmus of Tehuantepec. This being the 
case, it must live there in water of high temperature, probably about 65° F, I 
have an authentic specimen from shallow water on the coast of Peru. One char- 
acteristic of this species, almost unique in its group, is the presence of slightly 
elevated radiating lines visible only with a good light and under the lens. Fischer 
and Oehlert, in their report on the brachiopods of Cape Horn, figure some shells 
under the name of Liothyrina moseleyi Dav., which are lately referred by Bloch- 
mann,! on the strength of a specimen received from the Paris Museum, to ZL. wva. 
It is entirely possible that the specimens referred to L. moseleyi were mixed, and 
that a specimen of Z. wva was sent to Blochmann; but the specimens figured by 
Fischer and Oehlert are, as they state, more nearly circular in outline than typical 
L. uva, and come from water of a temperature between 6° and 8° C. (42°.8- 
44°.4 F.), which is much colder than that in which Z. wva is known to occur. 
Moreover, the ‘‘ Albatross” dredged a specimen, agreeing almost exactly with 
the Z. moseleyz of the Antilles, 150 miles off the coast of Peru, in 2222 fathoms, 
temperature 35°.2 F., and dead valves near Cocos Island. So the presence of 
L. moseleyi in the cold waters of Cape Horn would not be extraordinary, while 
if Z. wva is also present in that region one would expect to find it in the com- 
paratively shallow water, which is somewhat warmer than that of the deeps. I 
have not seen any specimens of Z. wva from south of Peru. 
Liothyrina moseleyi Davinson. 
U.S. S. “Albatross,” station 4656, in south latitude 6° 55’ and west longi- 
tude 83° 34’, in 2222 fathoms, mud, bottom temperature 35°.2 F. U.S. N. Mus. 
110,744. Also (dead valves, probably of this species) at station 3370, in 134 
fathoms, near Cocos Island, temperature 54°.8 F. 
The original locality of this species was west of Kerguelen Island, ‘‘ Chal- 
lenger ”’ expedition, station 148, in 210 fathoms, rocky bottom. 
A specimen believed to be of the same species was obtained off Martinique, 
West Indies, in 169 fathoms, temperature 51° F. It was identified by Mr. 
Davidson as being his species.

U. 8. S. “ Albatross,” station 3362, Gulf of Panama, in 1175 fathoms, mud, 
bottom temperature 36°.8 F. U.S. N. Mus. 107,275. Also at station 4709, 
southwest of the Galapagos Islands, in 2035 fathoms, ooze, temperature 35° F. 
A single specimen was obtained in each instance.
