Neir (I III/ Rare Fossils. ]7\ 



of New South Wales, is of tlie same type of shell as the above, and 

 may be regarded as a depauperated and sparsely coiled form of 

 the Ammodiscus type. The nearest allied examples to the above are

Genus FRONDICULARIA. Defrance. 



Frondicularia lorifkra', sp. nov. (Plate XVI., Fig. 6). 



Dexrriptioji. — Test, compi'essed ovate, with pointed extremities, 

 more acute at aboral end. Edges of test, blunt. Chambers 

 numerous, about fifteen. The surface of each acute V-shaped cham- 

 ber thickened with redundant shell-growth, especially towards the 

 oral area of each segment. 



Ditneiisions. — Length of type specimen. 4 nnii. ; gieatest width. 

 1.615 mm. ; thickness, .3 mm. 



Affinities. — In outline somewliat like the associated species of 

 Frondicularia in these borings, viz., F. inaequalis. It is distin- 

 guished from that form, however, by the wide angle of divergence 

 made by the two upper edges of each segment, and the exceptionally 

 heavy shell with thick, strap-like layers of redundant growth on 

 the lateral surfaces of the test. 



Distribution.— Bore 4. 163-170 feet. Bore 11. 4.38-440 feet.
