 Fig. 25. 



Description. — The glabella of this species is oblong, convex 

 with nearly parallel sides, well separated from the cheeks by the 

 deep dorsal furrow, the front rounded, and the neck furrow rather 

 deep all across. The eyes are small, situated a little behind the 

 mid-length of the glabella, and distant from the dorsal groove a 

 little less than one half the wfdth of the neck segment. The 

 marginal rim of the head is the same as in B. Saffordi. Sur- 

 ffice smooth. Length of glabella four lines ; width three lines.

Bathyurus Cordai. N. s. 

 Fig. 26. 



Description. — Glabella conical, with a deep sulcus all round ; 

 in front an elevated rim apparently forming a rostrum similar to 

 that of some species of Calymene\ just within the rim a deep 

 groove, between which and the furrow that surrounds the gla- 

 bella, there is a rounded ridge. Neck furrow well defined all 

 across. Eyes apparently about opposite the middle of the gla- 

 bella. Surface smooth. 



The glabella in some of the specimens is more narrowed to- 

 wards the front than it is in the specimen figured. 



Length of largest head seen, seven lines ; length of glabella, 

 five lines ; width just in front of the neck furrow, three lines and 

 two-thirds ; at one line from the front, three lines.
