REED (F. R. Cowper)—Continued 
He also remarks with regard to Ptychoparia that there happily cannot be any dis- 
pute as to the type of the genus, for Corda’s first described species, Ptychoparia striata 
Emmrich, is well known and universally acknowledged. 
Reed quotes Corda’s original description of the genus and renvarks that Pompeckj 
agrees with this strict limitation of the generic name Ptychoparia, but instead of re- 
garding it as a subgenus of Conocephalites, as Wallerius did, prefers to place the latter 
as a subgeneric division of the genus, which is followed by the author with C., Em- 
mericht Barrande, as a type. 
With regard to the genus Liostracus Angelin, the author quotes Matthew’s divisions 
of the genus Ptychoparia and Liostracus, and remarks that the only constant differ: 
entiating feature of value is the shape of the genal angle, spined or rounded. 
Matthew takes L. aculeatus as a type, but Broégger is followed by Wallerius in re- 
garding the genal angles as typically spined, as in L, costatus Angelin, Reed places 
the genus as a subgenus to Ptychoparia. 
Also Conocephalites, with C. Emmrichi Barrande, as a type. ‘The leading charac- 
teristics of it are: 1—the long narrow eyes; 2—the position of the eyes near the 
glabella; 3—the course of the facial sutures, which behind the eyes run out almost 
the furrow on the eye lobes; 5—the absence of 
horizontally before bending back; 4 
occular ridges; 6—the flat border.

Dicellocephalus interpres sp. nov. The author compares it with D, Dewinei Billings 
and other species, remarking that D. Dewinei and D. Hisingeri of Billings cannot 
rightly be retained in the genus Dicellocephalus.

The peculiar course of the marginal furrow, so as to make a broad V in front of the 
glabella, occurs also in several species attributed to Ptychoparia, P. sp. ind. Walcott, 
from Yellowstone, and P. teucer Billings. Vhe author compares 4. Angelini Gronwall. 
Anomocare sp. 
Schantungia Lorenz, 1906, 8. cf. freguens Dames. 
Reed remarks, that unfortunately the name Schantungia is apparently preoccupied, 
Walcott having employed it for a type of trilobites from China in 1905, but without a 
figure. If it is proved that the type of Walcott’s Shantungia and Lorenz’s Schantungia 
belong to different genera a new name must be given to this group or genus contain-
