him to indicate that the species is really a Pecopterig'. In this conclusion 

 I acquiesced, and omitted this species from the list in Acadian Geology. 

 Subsequently, however, I found, on comparing the specimens in Mr. Hartt's 

 collection with those I had previously obtained, that there are two species, 

 for one of which I retain the above name. 



70. Neuropteris retorquata. S.N. — (PI. XVII, Fig. 197.)— M.D., 

 Lepreau, New Brunswick. Col. Geol. Survey. 



Pinnules broad oblong, obtuse, curved obliquely, cordate or auriculate 

 ^ at base. Midrib faint, and traceable little more than half way 



from the base, nerves crowded, very oblique, curved,forking abou 

 twice. Basal pinnules orbicular, or reniform,with diverging veins. 



Numbers of scattered pinnules of this species occur on the surfaces of 

 the Devonian shales at Lepreau. It is a very distinct species, allied, how- 

 ever, to N. flexuosa and N. gigante,a of the Carboniferous. The pinnules 

 were either somewhat thick or strongly reflexed at the margin. In these 

 characters, as well as the form of the pinnules, it differs markedly from 

 N. polymorpha, with which it is associated in the beds at Lepreau. The 

 specimens described were collected by Mr. Weston of the Geological 

 Survey. 



71. Nbdropteris crassa, Dn. — (PI. XVII, Fig. 200.) — ^Acad. Geology, 



p. 551. — M.D., St. John, New Brunswick. 



A single pinnule is all that I have to represent this species. It was 

 collected by Mr. Lunn of St. John, N. B. . 



72. Neuropteris Selwyni, S. N.— (PI. XVII, Fig. 198.)~M.D., St. 



John, New Brunswick. 



Pinnate. Pinnules oUong, narrow at the point, curved upward. Tha 

 lower side oj the base cut off obliquely, so as to form a notch 

 between the pinnule and the petiole. Mid-rib distinct. Nerve$ 

 much, curved, forking once or twice. 



A single specimen represents this species in Prof, Hartt's collections 

 from St. John. I dedicate the species to the Director of the Geological 

 Survey. 



73. Neuropteris, sp.— (PI. XVII, Fig. 199.) 



A few fragments in my collections from St. John represent another 

 species resembling N. Sorettii, Brongt., but they are insufficient for 

 description.
