and sculpturing with the Russian species Cucullcea {Macrodon) ScJiourovskii 

 F. Rouillier, I do not hesitate to identify the pieces hefore me with the 

 species figured by Rouillier. 



In classing our species and Cucullcea elonrjata Sow. among the Macro- 

 dons, it must be observed that on account of the longer and less vertical 

 anterior lateral teeth i, this species differs somewhat from the type of the 

 genus Macrodon (ilf. Hirsonense Lye. Keyserlingi Lah. RouilUeri Trautsch.), 

 and approaches nearer to Cucullsea. 



Macrodon SchourovsM F. Rouillier sp. is embedded in grey, rusty brown 

 elay sandstone. Both pieces were found loose, the piece figured on PI. I. 

 fig. 17, at a height of circ. 500—550 feet north of Elmwood, the other on 

 July 12th, 1896, near the margin of the glacier, north west of Elmwood. 



In addition to the fragments of Lamellibranchiata here described, a piece 

 of clay sandstone with Cadoceras sp. indet (July 16th, 1896, 500—550 feet 

 above the sea, north of Elmwood) contains a fragment of a 



Lima sp. indet. (PI. 11. fig. 8a), whose shell-sculpturing consists of very 

 fine, close radial ribs. 



Among the numerous bivalve fragments occun-ing together with Pseudo- 

 monotis Jacksoni in hard, grey, sandy marl (Aug. 2nd, 1896, 30 ft above the 

 sea, north west of Elmwood), certain pieces point towards the genus Pleuromya. 

 This, however, cannot be settled with any certainty.

Amberleya sp. 

 Letterpress fig. 12. 

 In the material collected at Cape Flora Gastropoda are represented by a 

 single specimen only, belonging to the genus Amberleya, Morr. and Lye. 



The last whorl is broken off and the outer layers of the shell are lacking, 

 therefore specific determination of the specimen is impossible. The side of 

 the (last preserved) whorl bears three rounded, obtuse, spiral keels, which — 

 as far as can be seen on the imperfect remains of the outer layers of the 

 shell — had been crossed by (squamous?) radial striae (fig. 12 b). A fourth 



' And also because the height of the shell is the same in front of, and behind the umbo.
