SOME NEW DEVONIC FOSSILS 189 



compared. Both of these shells are from the Middle Devonic. 

 Beushausen figures as Macrocheilus ? sp. an internal cast of like 

 aspect and proportions from the Spiriferensandstein of the Ober- 

 harz (Bocksberg), identical indeed so far as identity can be in- 

 dicated by internal casts. Specially noteworthy is the agreement 

 in relative size of the final whorl and the explanate form of the 

 apertural margin. 



Lozver Devonic. Presque Isle stream. A shell of somewhat 

 similar character but apparently stouter with more convex whorls 

 occurs at Edmunds Hill, Chapman Plantation, Me. 



Coelidium strebloceras nov. 



An extremely elongate and terete shell with not less than 20 

 volutions at full growth. The best preserved specimen has a length 

 of 70 mm, and a width at the base of 11 mm. The later whorls 

 display a sharp median angulation with a moderately broad and 



Coelidium strebloceras 



distinct slit band from which the slope to the suture is abrupt, 

 more distinct and flattened above, more convex below. 



This singularly delicate " Murchisonia " carries to an extreme 

 the expression presented by some of the species described by Hall 

 from the Guelph and by Lindstroem from the Gothlandian. 



Lower Devonic. Dalhousie, N. B.
