Ill England, Belgium, and G-ermany this species is characteristic of 

 the Lower Coal Measures; in Arctic America it has been found on Berg- 

 Island," brought in by the Nares expedition. 



It is quite likely that Phillips's name, G. striolatum, will take precedence 

 over G. diadema, which Goldfuss left in manuscript, ;ind which Beyrich 

 afterwards published. 



A similar species has been described l)y F. Roemer'' under the name 

 Goniatites listen Martin, from Carboniferous limestone of Sumatra, although 

 this latter niay be Goniatites beyrichianum de Koninck. x\t any rate this 

 type of Glyphioceras is widespread, characteristic of Lower Coal ]\Ieasures, 

 and may be chosen as a zone fossil. It has not yet been found within the 

 United States, but may well be expected there on account of general 

 similarity of faunas of this horizon.

The following description is quoted from McChesney's last paper: 



Shell moderatel_v small, discoidal, much compressed. Volutions two to three, 

 strongly embracing, and concealing about two-thirds of the inner volutions; unil)ili- 

 cus comparatively wide and shallow. Dorsum [venter] extremclj' narrow, having a 

 linear depi'ession along its center; sides of the volutions very slightly and regularly
