64 THE NAUTILUS, 
NEW SPECIES OF TERTIARY MOLLUSCA FROM VANCOUVER ISLAND. 
BY JOHN C. MERRIAM. 
The species here described have already been mentioned by the 
author as being new forms in a short paper’ on the age and general 
character of two Tertiary faunas from the southern coast of Van- 
couver Island. 
These faunas were referred to two horizons occurring at different 
localities, one at Carmanah Point at the entrance to the Strait of 
Fuca, the other near Muir and Coal Creeks in the Sooke district. 
The horizon at the first-named locality was temporarily designated 
as the Carmanah Point beds, and is correlated with Conrad’s 
Astoria Miocene, excluding the lower portion of his series which 
has been supposed to be Eocene. The second horizon was named 
the Sooke beds, and is, as nearly as can be determined from the study 
of the known fauna, of Middle Neocene age. 
The material on which the deseriptions are based was collected 
by Dr. C. F. Newcombe, of Victoria, B. C., who has kindly per- 
mitted the author to study the extensive collections which he has 
made at both of the above-mentioned localities. 
Cytherea Newcombei n. sp. 
Shell subquadrate to oval, high, moderately thick, truncated an- 
teriorly. Beaks not prominent. Lunule faintly marked. Surface 
ornamented with numerous, irregularly placed growth lines and 
ridges. On some well-preserved specimens a large number of very 
faint radial lines are visible. Length of large specimen 70 mm., 
breadth 55 mm. Hinge of right valve with three cardinal teeth 
and a short pit for the anterior lateral tooth of the opposite valve. 
This pit for the reception of the anterior lateral tooth is shallower 
and much shorter than in the following species. 
Locality : Sooke beds, Vancouver Island. 
Cytherea vancouverensis n. sp. 
Shell oval, narrowly rounded anteriorly. Beaks prominent. 
Lunule well marked. The somewhat weathered surface of the 
shells ornamented by numerous, irregularly placed growth ridges. 
Length of type specimen 62? mm., breadth 48 mm. Hinge of right
