members of the Brachiopocla And Lamellibranchiaia, as yet unclassified.* 



A short distance to the north of Taylor's Point, in a light grey and 

 very coarse grained sandstone, a Lingula v.'as obtained, somewhat 

 resembling L. Lyelli and L. Nympha, but probably distinct specifically 

 from either of them. This will be an interesting form for future study. 



In front of the dwelling house of Mr. Btiillie, at high water mark, 

 there occurs another band of coarse granular sandstone, which is com- 

 posed almost altogether of the detached valves of brachiopods. In the 

 majority of cases the specimens show only the internal casts, good ones 

 showing the external markings being difficult to obtain. A sufficiently 

 complete series of these forms has, however, been collected for the iden- 

 tification of RhynGhonnlla orientalis, Orlhis imperator, 0. platys and a 

 species of Orthis, which may eventually turn out to be 0. pe^veta. Mr. 

 Baillie informs us that this bed was .met with in the excavation of a 

 well, a short distance from here, and the fossils found to be in an excel- 

 cellent state of preservation. 



The most important finds of the season, however, are referable 

 to a very heavy bed of brownish weathering sandstone about 10 feet 

 above the level of the band already indicated as occurring at hio-h water 

 mark. This bed has furnished us with a larger, moi-e varied, and more 

 interesting set of associated forms than any that has hitherto been met 

 with in this district; but, until it can be thoroughly worked up, it 

 would be premature to attempt to give anything more than a rough 

 preliminary sketch of the fossils it contains, some of which are the 

 following : 



Rh'jnohonella orienLdis, Ctenolonta (three species undetermined). 



Murchisorda n. sp. This form is allied to ^f. bicincta or to J/. 

 ventric08.%, and resembles some of the st)ecimen8 from the Min^an 

 Islands which are referred, in the Geological Survey collection, to the 

 former species. 



*Th(\se forms, which are probably those referred to in the Geological Survey 

 Eeport of 186:^, have been met with at Aylmer in a bed of very impure shale, asso- 

 ciated with Lingida Belli. Ju the same band there also occurs a number of large 

 circular flattened nodnles, from 1 to 2h inches in width, not nnlike, in general 

 appearance, I'asceoltis globosus. So far tliey have yielded no evidence of structure, 

 but it is not at all uulikidy tliat, as additional light is brought to bear upon them, 

 they may ultimately prove to be like those observed by Mr. Ami of organic 



on^'in.
