Modiella modiola nov. 



Plate 23, figures 1-5 



This is a more elongate, more slender and generally larger shell than 

 M. pygmaea, the posteriorly expanded and convex body of the shell 

 being narrower, the byssal sulcus less deep and the anterior fold very much 

 reduced in diameter. The shells are thus subacuminate or modioloid and 

 very obliquely arcuate. Average examples have a length of 19-24 mm. 



Locality. Portage road, Gaspe Basin. 



Phthonia cylindrica Hall 



Plate 22, figure 13 



Phthonia cylindrica Hall. Palaeontology of New York. 1885. v. 5, pt i, 

 P- 473, Pl- 78, fig. 1-4 



This smooth elongate and semicylindrical member of the genus 

 Phthonia is clearly represented by small shells, not attaining the dimen- 

 sions of the New York species. It has been elsewhere recorded only in 

 the Hamilton shales. 



Locality. Gaspe sandstone, Portage road, Gaspe Basin. 



Sphenotus truncatus (Conrad) 



Plate 22, figures 9-12 



Cypricardites truncatus Conrad. Acad. Nat. Sci. Phila. Jour. 1842.

 Sphenotus truncatus Hall. Palaeontology of New York. 1885. v. 5, pt i, 



p. 394, pl. 65, fig. I, 4-6 



This is an elongate shell with smooth subconcave median portion, short 

 umbonal ridge and broad postumbonal slope traversed by a low intermedi- 

 ary ridge. Specimens in the Gaspe sandstone are not distinguishable from 

 typical forms occurring in the Hamilton shales of central and eastern New 

 York. 



Locality. Portage road, Gaspe Basin. 



Schizodus appressus (Conrad) Hall 



Plate 23, figuie ii 



Schizodus appressus (Conrad) Hall. Palaeontology of New York. 1885. 

 V. s,pt I, p. 449, pl- 75, fig- 3-9 



A single very typical example of the species is present. Schizodus 

 appressus is a common species of the Hamilton fauna throughout 

 localities of western New York. 



Locality. Portage road, Gaspe Basin.
