There is a faint sign of concentric ornamentation. The superior extent of the 

 shell is slig:htly saddle-shaped. Tlie dimensions of the shell are : Leng-tn, 35 mm. ; 

 height. 15 mm. ; thickness, 7 mm. 



This form is represented by Specimen No. 4642 in the collection of the Geo- 

 logical Survey, and was obtained by Cullen from the parisli of Jlooroivarra. 



Edjiondia sp. indet. 

 This form is represented by Specimen No. 43G3 in the collection of the Geo- 

 loaical Survey obtained by Cullen from the parish of Moorowarra.* 



Ctexodoxta sp. index. 



A form provisionally referred to this species was obtained by Mr. Pittman 

 from Carroll . *

 This is represented by the cast of a single left valve covered with a little of 

 the original shelly material. It is nine mm. in height. The hinge line is seven 

 mm. long and shows no sign of teeth. The umbo is, three mm. from the anterior 

 end, and from it radiate many delicately marked striae crossed by a few concen- 

 tric folds. This form resembles P. arijutus (Phillips) of the European Carboni- 

 ferous, but is more delicately ornamented. It is named in honour of Mr. .J. E. 

 Carne. the late Government Geologist. It was collected liy Mrs. Scott from the 

 south-eastern portion of Babbinlioon.

 In the original specimen of this species the umbo was missing, and the form 

 could not, therefore, be distinguished from the Devonian form, P. pittmani. It 

 was suggested, however, that should further collecting yield forms with a well- 

 developed umbo, such differences might be found as would .justify the erection of a 

 new species — P. sub pittmani. The form originally described was obtained from 

 west of Mt. Uriari. and is in the collection of the Geological Survey.

 This form at first sight resembles a capulid genus, but the shape of the umbili- 

 cal region, and its relation to the posterior margin of the shell, together with the 

 presence of a slightlv developed posterior ear, lead to the conclusion that it ought 

 to be placed in Freeh's genus, Kochia. The umbo is a little posterior of the
