REED (F. R. Cowper) — Continued 



He also remarks with regard to Ptychoparia tliat 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 kiiown and uni\-ersally acknowledged. 



Reed quotes Corda's original description of the genus and remarks 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 diii, prefers to place the latter 

 as a subgeneric division of the genus, wliich is fL'llowed. by the author with ('.. Em- 

 merichi Barrande, as a type. 



With regard to the genus Liostracus .\ngelin, tlie author ()uotes Matthew's tlivisions 

 of tlie genus Ptychoparia and Liostracus, and retnarks that the oidy constant differ- 

 entiating feature of value is the shape of the genal angle, spined or rounded. 



Matthew takes L. actileatus as a type, but Brogger 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. Ernmridii 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, whicli behii^d the eyes run out almost 

 horizontailv before bending back; 4 — ilie furrow on the e.e lobes; 5 — the absence of 

 occular ridges; 6 — the flat border.

Dicellocephalus interpres sp. nov. The author compares it with D. De-^vinei Billings 

 and other species, remarking that D. Dcuiriri and D. Hisimrrri 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 Pt\choparia, /'. sp. inJ. Walcott, 

 from Yellowstone, and P. teuccr Hillini^s. 'V\\e autlior compares A. A/ij^cli/ii Gronwali.

Schantungia Lorenz, 1906, S. cf. frcf/uc/is Datnes. 



Reed remarks, that unfortunately the name Sciiantungia is appareiuly preoccupied, 

 Walcott having employed it for a type of trilobites from China in 19(15, but without a 

 figure. If it is proved that tiie type of Walcott's Shantungia ami I.orenz's Schantungia 

 belong to different genera a new name must be gi\en to tliis group or genus contain- 

 ing Dames' (!. frequens.
