DoUchometopus occidentaUs, Matthew, 1899 : Proc. «& Trans. Roy. Soc. Canada [2], 

 vol. V, p. 49, pi. ii, fig. 2. 

 Only one example known (12 ram. long by 8 mm. wide). 

 Eeferred by Matthew to Angelin's genus DoUchometopus, of which 

 only the head is known from Sweden. 



(Unique.) M. Cambrian : Mount Stephen. 



Agnostus interstrictus, White. ^ 



Probably there are several species of Agnostus from Mount Stephen, 

 A. interstrictus is certainly found there. 



" This species," says Walcott, " is very abundant at Antelope 

 Spring, Utah, where it is associated with Olenoides Nevadensis, as at 

 Mount Stephen." (Amer. Journ. Sci. [3], 1888, vol. xxxvi, p. 166.)

M. Cambrian : Mount Stephen, B.C. 



(Collected by Byron Walker, Esq., F.G.S.) Geol. Surv. Museum, 

 Ottawa. Mr. Walcott writes ^ as follows : — 



" HyolitJielliis micans, Billings. — Black, shiny, concentrically striated 

 or smooth, compressed tubes occur in the shale with the Trilobites, 

 that appear to be identical with H. micana of the Middle Cambrian 

 fauna of New York, Vermont, and Canada. These ' slender stems,' 

 mentioned by Dr. Rominger, may be the same as the slender shells 

 of this species which appear like compressed stems formed of shiny 

 carbonaceous matter." 



" It is doubtful what the specimen identified as Monocephalus 

 Salteri? is. It may be the young of Bathyiiriscus Hoioelli. The 

 specimen figured as Bathyurus'? is too badly defined to identify it. 

 Of the remaining genera mentioned by Dr. Rominger I do not find 

 any traces in the material before me with the exception of a fragment 

 of Orthis." 



" Kutorgina Prospectensis, Walcott ? — A fragment of a species of 

 Kutorgina, closely related to K. Prospectensis, occurs on the slate 

 in association with PtycTioparia Cordillera. It is not improbable 

 that it represents a new species." 



Among the specimens obtained by Mr. Whymper from Ball's 

 Valley, 23 miles distant from Field, may be mentioned Ogygopsis 

 Klotzi, BaihyuriscusHowelli, Ptychoparia C'ordillerat{se\en specimens), 

 Agnostus interstrictus, Stenotheca rugosa, etc. 



Dr. J. F. Whiteaves, F.G.S. , Palceontologist to the Geological 

 Survey of Canada, gives in The Canadian Record of Science, 1893, 

 vol. v, pp. 205-8, a figure and description of a new genus and 

 species of Phyllocarid Crustacean from the Middle Cambrian of 

 Mount Stephen, B.C., of which Mr. Edward Whymper also secured 

 four examples, one of which is figured here.
