Loc. Burrier (D). 



Hor. Wandrawandian Series. 



Obs. Very abundant both as casts and as testiferous 

 examples. Internal casts of this species show pittings 

 similar to those on specimens from Bundanoon. They 

 appear as small elevations on the cast, not more than A of 

 an inch in diameter. They are very irregularly scattered, 

 and are never present on the posterior side of the keel. In 

 the space of one square inch 29 were counted. The irregu- 

 larity of their occurrence evidently denotes that they are 

 not structural, and in addition to this they are not present 

 in all specimens. Possibly they are the product of some 

 corroding disease. In the original figure several pittings

Loc. Burrier (D). 



Hor. Wandrawandian Series. 



Obs. Only one specimen was found, an internal cast of 

 both valves. Whether this specimen is really a Macon in 

 is open to considerable doubt. The flat unkeeled valve 

 and the absence of a gape, evidently remove it from the 

 genus, but the specimen is not well preserved and approach- 

 ing very closely to Dana's Maeonia ? recta, 1 it is retained 

 provisionally under that species. 

 Oleobis grandis, Dana. (Amer. Journ. Sc. 1817, iv, p. 154). 



Obs. Large shells evidently referable to Dana's xp.vic< 

 are fairly abundant at Burrier. Casts show the hinge line 

 to be edentulous. The adductor muscular impressions are 

 faint, the anterior being the more prominent; and the 

 pallial line is simple.
