Northwest side of Hornby Island, W. Harvey, 1892: a single speci- 
men, about four inches and a-half in its maximum diameter, which is 
apparently referable to this species. Its volutions, however, are more 
nearly circular than those of the type of Ammonites Indra, as described 
and figured by Stoliezka. and than those of the specimen from Hornby 
Island collected by Mr. Richardson in 1871. Its surface, also, is marked 
by numerous but very faint and almost obsolete spiral ribs, in addition 
to the usual and equally faint curved transverse furrows and fine lines of 
growth.

Middle of east side of Denman Island, W. Harvey, 1892 : four fine 
specimens, one a little less and three a little more than four inches in 
their maximum diameter. 
The specimen from Norris Rock, south of Hornby Island, which was 
referred to this species, though with some doubt, in the second part of 
the first volume of “ Mesozoic Fossils,” is a fragment of the inner whorls, 
a little more than two inches in diameter, which has been described in 
detail and figured. Three of the specimens from Denman Island have at 
least seven of the volutions preserved, and all four are referred with 
some confidence to A. Jukesii, which proves to be a Lytoceras, as suspected 
in 1879. In one of these specimens (figure 2) the sculpture of the test is 
beautifully preserved on the outer volution. It consists of very narrow, 
sharp and prominent simple transverse ribs, which curve convexly forward 
next to the umbilical margin, but are nearly straight on the sides and 
periphery. At the commencement of the volution these ribs are two
