 Syn., Mania Burm., 1843; Organization Trilobites, p. 116 (Ray Soc. 

 ed., p. 100). Burmeister separates Dalman's species Caly- 

 mene concinna from the type of the genus Proetus, and 

 gives it the new generic name of jEonia, with descriptions 

 and figures of A. concinna, A. stokesii and A. verticalis. 

 Phceton Barr., 1846; Notice Prelim., p. 62. The author herein 

 gives the new generic term Phnton for species of Proetus 

 with fimljriated pygidia. 

 Prinopeltis Cord., 1847; Prodr., p. 121. New generic name 

 proposed for the preoccupied term of Phceton. Pygidium

 Goniopleura Cord., 1847; Prodr., p. 80. This genus includes 

 such species as Proetus elegantiilus Loven, with twelve seg- 

 ments in the thorax. 

 FoRBESiA McCoy, 1847; Sil. Foss. Ireland', p. 46. This author 

 uses for the types of his genus Forbesia latifrons and /'. 

 stokesii, which is the same as that used by Barrande in 

 1846 for his genus Phceton and Angelin in 187S for the 

 geniis Phatonides. Geual angles produced into long spines; 

 pleura> of the pygidium segmented; glabella furrows present 

 and large tubercles terminating the neck furrow. 

 Gerastos Goldf., 1843; Neues Jahrbuch ftir Mineral., p. 557. This 

 genus is a Proetus with (t. Icevigatus for its type, a specie.s
