undulaioplicatus, Roemer, and /. diversus, Stoliczka, as mere synonyms 

 of /. digitatus. Mr. Stanton adds, in effect, that although none of 

 Schmidt's figures of /. digitalis exactly duplicate those of /. undidato- 

 plicatus in the ' Mcsozoic Fossils,' it still seems to him most likely that 

 the Vancouver specimens are young individuals of /. digitatus, a con- 

 clusion in which the present writer entirely concurs." 



Similar specimens were collected in 1901, at Extension Tunnel, near 

 Nanaimo, by Mr. Harvey; and at Brennan Creek, V.I., by the Rev. G. 

 W. Taylor. One of these specimens from Extension, which is nearly four 

 inches and a quarter high, and apparently about as long as high, is very 

 similar to some of the Saghnlien specimens of /. digitatus that are 

 figured by Dr. Schmidt. A fragment of a valve that is probably referable 

 to this species and that shows its characteristic surface markings, was 

 collected at the west end of Lasqueti Island by Dr. G. M. Dawson in 1885. 



The specimen from Blunden Point collected by Mr. Richardson in 1872, 

 and the two specimens from Extension recently collected by Mr. Harvey, 

 are the only large ones from Canada that the writer has seen, though small 

 ones, that are not much more than two inches in their greatest diameter, 

 and usually less, are not uncommon in the Vancouver Cretaceous. 



A few small specimens, with numerous fine concentric ridges but no 

 indications of any divaricating plications, that were referred to /. niT/ti- 

 lopsis, Conrad, in the second part of this volume, were collected at the 

 Trent River and Bradley Creek, V. I., by Mr. Richardson, in 1872.* 

 They are probably young specimens of /. digitatus in which the divari- 

 cating plications are not yet developed, such as are figured by Schmidt 

 on Tafel vii, figs. 8, 9 and 10, of his memoir on the Cretaceous rocks of 

 Saghalien. Similar specimens were collected on th» Puntledge River, 

 near Comox, by Dr. Newcombe and Mr. Harvey, in 1892. 



The specimen from the Nanaimo River referred to by Mr. Etheridge 

 as "No. 22, Itiocef'amns mytilopsis," in one of the lists of fossils in Sir 

 James Hector's paper " On the Geology of the Country between Lake 

 Superior and the Pacific Ocean," and in Captain Pa] User's ofiicial report, 

 as elsewhere stated, f is a very small right valve of Inoceramus Van- 

 coiiverensis.
