Maple Island, Skidegabe Inlet, Dr. Newcombe, 1895 : a distorted 

 specimen, about five inches and a half in its greatest diameter. Cum- 

 shewa Inlet, Dr. New combe, 1895 : one rather worn specimen. As 

 Ammonites Buddha was first described by Forbes on page 112, and 

 A. Sacya on page 113 of the same volume of Transactions of the 

 Geological Society of London, it seems to the writer that the former of 

 these two specific names should have been retained for this species.

East end of Maud Island, Dr. Newcombe, 1895 : one specimen. An 

 imperfect but well preserved and characteristic specimen in the Museum 

 of the Survey, which is clearly referable to this species, was collected in 

 the Cretaceous rocks at Comox, Vancouver Island, by Mr. Walter Harvey 

 in 1891.

Amended description. — Shell large, narrowly elongated, usually sinistral, 

 but apparently sometimes dextral : volutions widely separate longitudi- 

 nally, slightly compressed on the venter and dorsum, broadly subovate or 

 almost circular in transverse section, and coiled obliquely in such a way 

 as to leave a rather wide empty space, of the nature of an umbilical per- 

 foration, in the middle of each. Surface markings consisting of small 

 close-set, low, transverse ribs, and of comparatively distant spines or 

 tubercles. Sutural line not clearly shown in any of the specimens that 

 the writer has seen, but the siphuncle forms the median line of the 

 venter. 



The smallest but much the most perfect of the three specimens of 

 Spiroceras Carlottense from Cumshewa Inlet, described in the third part 

 of this volume, must be regarded as the type of that species. It shows 

 that the ribbing is rather faint, and that there are three spinous tuber-
