Type Specimens of Radiolaria and Eurypterida

RADIOLARIA
Introduction and Locality

This section of the catalogue of type specimens of invertebrate
fossils in Walker Museum is devoted to the Radiolaria in the Aber-
deen collection. Holotypes are designated here for species originally
based on cotypes. Catalogue numbers were given to glass slides,
some of which contain several species. Therefore the same number
may identify more than one species. Two new names here proposed
to replace homonyms were supplied by W. R. Riedel. For more
detailed location of specimens on slides see Riedel and Foreman
(1961). Walker Museum specimens are identified by the letters U.C.

Locality 55. — Fragments of the Santiago Chert Member of the
Caballos Novaculites from the hogbacks lying l}/£ miles east of
Marathon, Texas.

EURYPTERIDA

Introduction and Localities

This section of the catalogue lists the type specimens of eurypte-
rids in the custody of Walker Museum of Paleontology, the Univer-
sity of Chicago, and Chicago Natural History Museum. Walker
Museum specimens are identified by the letters U.C; the Chicago
Natural History Museum specimens by letters P and PE.

Holotypes are designated for species if no prior selection has
been made. Photographs are presented for specimens not ade-
quately illustrated in previous publications.

Locality 56. — A large stone quarry in Monclova Township (S. ^,
sec. 29), Lucas County, Ohio, commonly known as the Holland
Quarry. Operated for many years by the France Stone Company.
Two miles north of the small village of Monclova, three miles south-

Clarke and Ruedemann, 1912, to Eurypterus (Onychopterus)
kokomoensis Miller and Gurley, 1896; by Kjellesvig-Waering,

The holotype consists of a carapace and its counterpart.

Eurypterus potens Hall, 1884. Figure 20.

Holotype: here designated, the specimen shown by Hall, 1884:
U.C. 12297 (fig. 10, pi. 4).

Referred specimen : the other specimen figured and cited by Hall,
1884: U.C. 51876 (fig. 9, pi. 4).

factorily to genus and species. He interpreted the fossils as
the fragments of the ectognaths. Clarke and Ruedemann,

and a gnathobase, with ornamentation characteristic of E.
mansfieldi. Referred by Clarke and Ruedemann, 1912, to
Eurypterus (Anthraconectes) mansfieldi C. E. Hall; by Kjelles-
vig-Waering, 1958, to Adelophthalmus potens (Hall).
