Family HYPHASMOPORIDAE Vine, 1885 
Genus STREBLOTRYFPA (Ulrich MS.) Vine 1884b 
YPE SPECIES. Streblotrypa nicklesi (Ulrich MS.) Vine, 1884b, by 
onotypy, from the Lower Carboniferous of Hurst, Yorkshire, Eng- 
and and Illinois, U.S.A. 
TYPES. 
Duncan (1949) has discussed the problem of Vine’s lost 
material and the implications for the type specimens. She designated 
a suite of specimens collected by Ulrich in North America (USNM 
43311) as (neo)types. Indeed, she should have only designated one 
neotype. Hageman (1993) has designed one of Ulrich’s syntypes 
(USNM 114392) as the neotype. 
DISCUSSION. Confusion has existed over the authorship and the 
concept of the type species of the genus. J.M. Nickles of the U.S. 
Geological Survey sent specimens of a bryozoan from the Carbon-
