supplementary loljes in Dr. H. Woodward's excellent figures of 

 either Fhillipsia or Griffithides. The one preserved is, how- 

 e\'er, very distinct in our specimen, quite separated from the 

 basal lobe on the one hand, and the neck segment on the 

 other. The glabella is densely ornamented with very minute 

 prickles (pits in the cast), but although these ai'e not certainly 

 visible on the thorax and pygidium, still a roughening of the 

 surface may, perhaps, indicate their former presence. 



The supplementary lobe is present in some Proetl, such as P. 

 bohemicus, Corda,* for instance ; and the late Mr. J. W. Salter 

 made the following remarks on the subject! : — " A very usual 

 character of this genus [Proetas] is the jDossession of a strong 

 tubercle, terminating the neck segment on each side, and nearly 

 separated from it. Burmeister, however, in his second edition, 

 has considered the species having this thickening, and the obscure 

 glabella furrows more strongly marked, as forming a distinct 

 genus, which he calls ^Eonia. McCoy had anticipated him by a 

 few months in the name Forbesia, without referring to Proetus."
