In Belgium, this form occurs in Stage VI. of the Carboniferous Limestone 

 at Vise. It is also found at Bolland, in Yorkshire, near Glasgow, and in the 

 Chester Group (Upper Mississippian) in Illinois. 



Naticopsis obliqua, sp. nov. (Plalc xxii., figs. 13, 14.) 



This form has some resemblance to A', consimilis (De Kon.), but dilt'ei-s 

 from it specifically. It is also quite unlike any American form of which we have 

 information. It is an internal cast, the spire consisting of five or six whorls. 

 The last whorl is for the most part below rather than around the preceding 

 whorls. The distinguishing feature is the very eccentric position of the spire in 

 regard to the upper surface of the last whorl. 



The dimensions' are as follow : — Height of spire, 13 mm. ; breadth of base, 

 18; height of aperture, 14; breadth of aperture, 8; angle of spire, 115°. 



The specimen was obtained by Mrs. Scott in the south-east of Babbinboon, 

 and is No. F 12460 in the collection of the Geological Survey. 



Macrocheilus filosus (Sowerby). 



lAttorina filosa, Sowerby, in Mitchell's Three Expeditions into Eastern Australia, 



1838, p. 15, 38, t. 3, f. 5: Morris, in Strzeleeki's Phys. Descr. of X.S.W. 



and Van Diemen's Land, 1845, p. 285, t. 18, f. 14; Macrocheilus filostts, 



De Koninck, 1877, Pal. Foss. N.S.W., (1898), p. 264, t. 23, f. 16. 



This form was among the first fossils found in the district, and was obtained by 



Mitchell at Perimbungav. just below the junction of the Peel and Namoi Rivei-s. 



PLATrCERAS SP. IXDET. 



Specimen 1811 of the collection of the Geological Survey has been referred 

 to this genus. It was obtained near Carroll. 



LOXOXEMA BABBINB00XEN8I.S Etll. fil . 



Etheridge, Junr., Rec. Geol. Surv. N.S.W., viii., 1907, p. 194, t. 38, f. 5, (i. 

 This form was collected by Stonier from the parish of Babbinboon, and 

 probably near the south-eastern portion. 



LOXONEMA .SP. IXDET. 



Rec. Geol. Surv. N.S.W., viii., 1907, p. 195, t. 37, f. 4, 5. 

 This form, aceoi'ding to Etheridge, resembles L. lefevrei and other species in 

 ornamentation, but is not identical with any of them. It wa-s obtained by 

 Porter from Carroll. 



LoxoxEiiA SP. IXDET. (Plate xxii., figs. 11, 12.) 

 The specimens figured were obtained by Mrs. Scott from the south-east of 

 Babbinboon. These are greatly weathered examples, possibly of L. rwjifera. 



Specimens of Loxonema, generally in an obscure and imperfect state of pre- 

 servation, are very abundant in the last-mentioned locality. Mitchell was jtro- 

 bably referring to a Loxonema when he mentioned the presence of Terehra in this 

 region . * 



COXUI.ABIA SP. IXDET. 



An indeterminate lorm, possibly referable to this genus, was oblalued hy 

 Benson, four miles east of Currabubula. Another example has been reported 

 from Somerton.
