68 Results of the Challenge Expedition. 



Localities. — Blackfellow's Diggings, Rockhampton, Queens- 

 land (Daintree Collection). F.fossula, Lonsdale, is recorded 

 from Mount Wellington, Tasmania [Morris) ; St. Patrick's 

 Plains and Raymond's Terrace, New South Wales {Morris) ; 

 Bell's Creek and Darlington, New South Wales (McCoy) ; 

 Glendon, New South Wales (Dana) ; Smithfleld Reef, 

 Gympie Goldfield, Queensland (Etheridge). 



Fenestella. Figs. 2 and 2a. 



Fig. 2 represents another species of Fenestella from 

 Gympie, as a cast in yellow sandstone, evidently the remains 

 of a large and handsome species. The fenestrules appear to 

 have been oval, and tolerably large in proportion to the 

 other parts ; the interstices bore two rows of cell-apertures, 

 separated by a small flexuous keel, from four to six cell- 

 apertures to each fenestrule. In places a third row of cells 

 is developed, especially previous to the bifurcation of the 

 interstices or stems. This species has somewhat the appear- 

 ance of Lonsdale's Fenestella internata (Darwin's Geol. Obs. 

 Vole. Islands, App. p. 165 ; Strzelecki's Phys. Descr. N. S. 

 Wales, &c. p. 269, t. 9, f. 2) ; but it is apparently too large, 

 and there are too many cells to the fenestrule. As there is 

 only one specimen, and that a cast, I refrain from giving to 

 it any new specific name. 



Locality. — Gympie, Queensland (Daintree Collection).
