[WILLIAMS] FOSSIL FAUNAS OF THE ST. HELEN'S BRECCIAS 239 



i\Ir. Schuchert refers to the same fossil in a paper " on the Helder- 

 bergian Eossils near Montreal," published in IDOl^ under the name 

 " Spirifer macra, Hall," remarking as follows : " This is the shell 

 referred to by Dr. Ami and the writer as like S. pennatus = S. mucro- 

 natus. The lest specimens were collected by Mr. E. Ardley, and are now 

 in the Redpath Museum. The shell differs from the long-hinged Mar- 

 cellus variety of S. pennatus in having a wider ventral hinge area and no 

 distinct bilobation of the ventral medial fold, cliaracters in harmony with 

 S. macra. It is closely related to S. pennatus, but more directly with S. 

 macra. and is considerably removed from S. cumberlandiœ of the Oris- 

 Jcanian. There is no shell in the Helderbergian with which it can be 

 compared." 



The fine series of specimens of this same fauna obtained from the 

 beach on Côte St. Paul has furnished the basis for the above 

 definition of its peculiarities, which I have regarded varietally nearer 

 8p. pennatus than -S*. macra, and for wliich the name Eelence is pro- 

 posed. 



2. Chonetes (Eodevonaria) hudsonicus metatype gaspensis, Clarke. 

 ' ( See comments on this species under species No. 8 of the St. Helen's 



lot 252.1). 



3. TentacuUtes Schlotheijni, Koken (cf. T. elongatus. Hall). 



In my original identification of these specimens I referred them to 

 the Middle Devonian species T. bellulus. Hall, on the basis of their 

 small size, regular annulation, slender form and absence of concentric 

 striations upon the annulations. More careful search of the specimens 

 has revealed parts of somewhat larger specimen's and some on which the 

 exposed surface shows the fine close striae covering the annulations, a 

 character by which T. elongatus is distinguished from T. bellulus.^ 



Specimens, corresponding in size and other characters, occur in the 

 Chapman sandstone of Aroostook County, Maine, and Clarke refers to 

 specitfnens under the name T. elongatus, Hall, from the Grande Grève 

 limestone which present the surface characters of T. elongatus but the 

 Grande Grève 'specimens are not so large as those of New York and they 

 appear to taper somev/hat more rapidly .^

2 Hall, J., Pal. N. Y., Vol. V, pt. II, 1879, p. 170. " In its general character 

 it resembles the T. elongatus of the Lower Helderberg group ; but the annulations 

 are proportionately stronger ; a little more closely arranged and not covered by the 

 striae as in that species."
