NO. I2 PERMIAN BRACHIOPODS FROM OREGON—COOPER 63 
PUNCTOSPIRIFER sp. 1 
Plate 11B, figure 6 
A single poorly preserved brachial valve and a few other frag- 
ments assignable to this genus have a broad but fairly strongly 
elevated and angular fold. The flanks are depressed and marked by 
5 subangular costae. The best brachial valve (U.S.N.M. 125407) is 
16 mm. long and 19 mm. wide. The external ornamentation is not 
preserved on the figured specimen but a fragment of another speci- 
men has marked varices of growth and small papillae. 
Types.—Figured specimen, U.S.N.M. 125407. 
Localtttes—Stio1; U.O. 2218-2. 
Discussion—The specimen on which the foregoing description is 
based is poorly preserved and the pedicle valve is missing. Never- 
theless, there is a striking resemblance to a Russian specimen re- 
ferred to Waagen’s S. ornata by Tschernyschew (1902, pl. 37, fig. 9). 
The Oregon species also bears a resemblance to S. holzapfeli which 
is similar to Tschernyschew’s specimens of S. ornata. The Oregon 
species differs from both of them in having a broader and much less 
elevated fold. 
PUNCTOSPIRIFER sp. 2 
A spiriferinoid having closely spaced concentric lamellae is as- 
signed to this genus but the specimen is too fragmentary for descrip- 
tion or figuring. It is mentioned only for completeness sake. 
Type.—Mentioned specimen, U.S.N.M. 128253. 
Locality —U.O. 2201-1.

HUSTEDIA sp. 1 
Plate 12E, figures 42-44 
Small, longer than wide, elongate oval in outline; posterolateral 
margins concave; lateral margins narrowly rounded; anterior margin 
broadly rounded. Lateral profile gently convex, anterior profile 
moderately convex; umbo narrowly swollen, the swelling continued 
| throughout the median region. Surface marked by 12 costae. 
Measurements in mm.—Figured specimen, length 8.0, width 6.4. 
Type.—Figured specimen, U.S.N.M. 127578. 
Locality —S25. 
Discussion —This is a poorly preserved specimen and might belong
