tures and characters of the polyzoary, the following genera appear to be 

 represented -.Monotrypeila, Batostoma, Homotrypa, etc., forms similar 

 to those from the Trenton rocks of Canada and elsewhere. 



Brachiopoda. 



5. Acrotheta sp. A small but interesting specimen of this genus 

 occurs in the collection, but its specific relations are not yet definitely 

 ascertained. 



6. Acrotheta sp. indt. 



7. Discina or Lingula, sp. indt. 



S. Schizotreta cf. *S. mimitula, Winchell and Schuchert. Two 

 valves, one a brachial and the other a pedicle-valve of this interesting 

 genus, occur associated with numerous other species of brachiopoda. 

 They closely resemble the above species to which they are referred with 

 some doubt whilst they also indicate close relation to Discina Pelopea, 

 Billings, a true species of Schizotreta. 



9. Paterula, sp. nov. An interesting form of this genus rare in 

 America was collected in the limestones at Mountain Hill, Quebec. In 

 general outline and leading characters it resembles closely P. Bohemica, 

 Barrande, but is probably distinct. This species is certainly distinct 

 from another species discovered by Mr. Weston in the rocks adjoining 

 the Montcalm market, Quebec, and figured by Hall in his Vol. VIII. of 

 Pal. N. Y. State, on Brachiopoda. This species of Paterula very closely 

 resembles a form collected by Prof. L. W. Bailey in the black limestones 

 of the Becaguimic Valley, in New Brunswick, in 18S4, but is much 

 smaller, being only one millimetre in length. 



10. Lingula Nympha, Billings. A rather large individual of what 

 appears to be a species identical with the above which was originally des- 

 cribed from Newfoundland. The septum, central scars and other 

 characters of generic importance are clearly visible, and the general out- 

 line of the shell make it very probaole that this "Quebec Group" 

 species occurs at Quebec also. With this species compare L. Elderi, 

 Winchell and Schuchert. 



11. Lingula, sp. Resembles one of the forms from the "market 

 rocks" of Quebec probably " species No. 1 " of my appendix to Dr.
