LIOTHYRINA OEHLERT. 
Liothyrina uva BRopERIP. 
This species was originally described from shallow water, 8 to 12 fathoms, off 
the west coast of 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 ZiotAyrina moseleyi Dav., which are lately referred by Bloch- 
mann,! on the strength of a specimen received from the Paris Museum, to L. uva. 
It is entirely possible that the specimens referred to Z. moseleyi were mixed, and 
that a specimen of Z. uva was sent to Blochmann ; but the specimens figured by 
Fischer and Ochlert are, as they state, more nearly cireular in outline than typical 
L. wva, 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. uva is known to occur. 
Moreover, the ** Albatross” dredged a specimen, agreeing almost exactly with 
the Z, moseleyi of the Antilles, 150 miles off the coast of Peru, in 2222 fathoms, 
temperature 359.9 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 
tL. uva 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 
ave not seen any specimens of L. uva from south of Peru. 
Liothyrina moseleyi Davipson. 
USS, ** Albatross,” station 4656, in south latitude 6° 55^ and west longi- 
tude 839 34’, in 2222 fathoms, mud, bottom temperature 35°.2 F. U.S, N. Mus. 
110,744, Algo (dead valves, probably of this species) at station 3370, in 134 
athoms, near Cocos Island, temperature 54°.8 F. 
The original locality of this species was west of Kerguelen Island, ** Chal- 
enger ” expedition, station 148, in 210 fathoms, rocky bottom. 
` A specimen believed to be of the same species was obtained off Martinique, 
osy Indies, in 169 fathoms, temperature 51° F. It was identifed by Mr. 
avidson as being his species.
