5. Stroplionella punctulifera, Conrad. 



A single specimen shows the surface character of this species. It 

 appears to be resupinate. 



6. Orthothetes cf. woolwortliana, Hall. 



Several fragments are clearly Orthothetes, but none of them are 

 complete enough to positively identify with any particular species though 

 presenting characters of the corresponding part of the shell identified 

 with 0. woolwortliana from the lot 2. 



7. Leptœna rhomb oidalis, Wilckens. 



Two imperfect specimens present the characteristic form and sur- 

 face of the variable form Leptœna, rhomboidalis. 



8. Camarotœchia cf. ventricosa. 



Two fragments present the gibbous form, rounded plications and 

 the size and proportion of this species. 



9. Rhynchonella cf. formosa. Hall. 



A single specimen of about the size and form of figure 6f. of 

 Hall's plate 35 i is referred to this species. It represents one of the 

 more finely plicated varieties of the species, which is abundant in the 

 lot 2 the other side of the dyke from this mass. 



10. Atrypa reticularis. 



'This species is represented by a single specimen showing both 

 valves, 21 mm. broad and witli the same form and surface markings 

 as the species in lot 2. 



11. Spirifer cf. concinnus. 



A specimen with rather narrow sinus, shows approach to the 

 characters of 8. cumherlandiœ in the region of the beak and is referred 

 to the species S. concinnus on account of the flattening and broadening 

 of the sinus toward the front. 



From the list of species here sho^vn it is evident that the same 

 fauna is present which is more fully represented by lot No. 2, the Gyphi- 

 dula pseudogaleta fauna.

 Comparison shows this to be identical in form and kind of rock, 

 fhe same as the specimens obtained at Côte St. Paul and defined by me 

 under the name Spirifer pennatus var. Helenœ I discover in these
