 meter. A little of the shell is preserved on the cast, and the sutural 

 line is excellently well shown.

Seven fine examples of this beautiful species, three of which are now 

 in the Museum of the Survey, were collected at Denman Island, near 

 Hornby I-land, in the Strait of Georgia, by Mr. Harvey, four in 1892 

 and three in 1895. A characteristic fragment, also, of G. Denmanense, 

 was collected at Hornby Island by Mr. Harvey in 1892. A small speci- 

 men, some forty-three millimetres in its greatest diameter, collected at 

 Brennan Creek, V. I., by the Rev. G. W. Taylor in 1901, is probably 

 referable to this species. The only other specimen of this shell that the 

 writer has seen is the fragment from Norris Rock referred to, under the 

 m,m.Q Ammonites Jukesii, on page 112, and figured on Plate 13, of the 

 second part of this volume.

Four specimens, that agree very well with Stoliczka's description and 

 figures of Ammonites Tiinotheanus, have recently been found in the 

 Vancouver Cretaceous. The specimens, which are now in the Museum of 

 the Survey, are, at any rate, essentially similar to those from the Queen 

 Charlotte Island Cretaceous that are referred to A. Timotheanus in the
