This is a shell, abundant though poorly preserved in some of the sand- 

 stone blocks, which I should identify with S . carinatus Schnur were it 

 not for the presence of fine and crowded lamellae which cover the surface. 

 S. carinatus has been often described and illustrated from the Coblent- 

 zian, most recently by Kayser in Fauna des Hauptquartzits, 1889, page 24, 

 plates i, 10, 14 and Scupin, Die Spirifcrcn Dcutschlands, 1900, page 26, 

 plates 2, 3. S . p er i m e 1 e is a shell of medium proportions with rela- 

 tively narrow cardinal area extending to the full width of the shell ; its fold 

 and sinus are conspicuous and rounded, relatively narrow, the fold some- 

 times becoming angular near the front. There are 10 to 12 rounded, 

 closely appressed plications on each lateral slope, with narrow intervals. 

 The sculpture when well preserved, which is not often, consists of subequi- 

 distant concentric elevated lines without trace of radii or fimbriae. The 

 interior of the ventral valve shows a narrow but rather long ovate muscle 

 scar which is not deeply depressed and is bounded by short dental lamellae. 

 Fuller description of the shell can not now be given but these features are 

 sufficient to indicate a dissimilarity with any known American Spirifer of 

 this horizon. 



Locality. Moosehead lake, Tomhegan and Baker Brook points, Me.

While identifications of the smaller fimbriate species of the early 

 Devonic are confessedly obscure, I refer to this species certain shells having 

 the general style and degree of plication, convexity etc. of this Helder- 

 bergian species. At the same time it is necessary to admit that distinctions 

 between the forms referred to S. cyclopterus from Grande Greve, 

 Perce, central Maine and New York, and the specimens passing as S . 

 s a f f o r d i and Oriskany forms of S . f i m b r i a t u s, are slender and 

 variable. 



Locality. Moosehead lake, 7 miles north of Kineo. 



Spirifer 



Of the other fimbriate Spirifers in these faunas there is abundance of 

 obscure remains not well preserved and difficult of exact identification. 

 All are small species and among them is recognizable the form which has 

 already been indicated as S. saff ordi in the Grande Greve fauna. 



Locality. Telos lake dam.
