East side of Dawson Bay, Lake Winnipegosis, on a small island about 

 two miles north of Whiteaves Point, (three well presei'ved ventral valves, 

 one of which is figured), and on another small island about the same dis- 

 tance to the south-west of that point (two similar specimens) ; J. B. 

 Tyrrell, 1889. 



These specimens are obviously much more like Davidson's figures of 

 Lcptama intfrntriiiJis than they are to Hall's illustrations of the very 

 closely allied Stri>p]iniliiiita vtUKqiiiniriatd ul Conrad, in the fourth volume 

 of the Paheontology of the State of New York. Prof. H. S. Williams, of 

 Cornell University, Ithaca, to whom three of the best of these specimens 

 were sent, for comparison, thus writes concerning them. The ventral 

 valve figured "is u good representative of the Li-pta;na 'hitn-s/rinlis, 

 Phillips, as it appears at Lummaton, in South Devonshire. I have com- 

 pared it with good specimens identified by Davidson. Our Strojiliodaiita 

 iiueqwisti-idta, S. I'nJi'rsoiti and S. Cdijiiln are allied forms, but your spe- 

 cimens are closer to the Lummaton forms than to either of our New York 

 species." Davidson's figure of L. iiiti'rutridlh on plate iii of the "Supple- 

 ment to the British Devonian Brachiopcxla," leave no doubt on the mind 

 of the present writer that Phillips' species belongs to Hall's genus Stro- 

 'pliodonta.
