at about 50° ; in these no fossils have as yet been found. They 

 resemble in general character the great mass of highly folded 

 unf'ossiliferous slates between this locality and Quillia. Above 

 these slates comes a crushed calcareous flaggy sandstone (a) full 

 of Bafinesquina expansa. In the quarry near Hanimondville at the 

 south end of the ridge the intrusive diabase is seen to be in contact 

 with a gi-eyish limestone, which is split up at this spot by thin shaly 

 bands (6) containing very abundant Entomostraca, Thick bedded 

 limestone (c) is found well exposed in a large quarry towards the 

 north end of the ridge, and is the source of the majority of the 

 fossils. It is a very tough bluish-grey rock when freshly broken, 

 but weathers into a rotten brownish material. Perfect specimens 

 are difficult to extract from it. It dips into the hill at about 45° 

 N.W. and overlies the above-mentioned beds. Above it is a bedded 

 felsite, which also can be traced sweeping round the northern end 

 of the hill. In a lane at the north-west corner of the hill a sandy 

 fossiliferous limestone is found dipping SSE. at about 60°, and con- 

 taining Orihis crispa, Bafinesquina expansa, and Steuopora fibrosa. 

 Thus we seem to have a synclinal existing in the hill. The diabase 

 exposed in the southern quarry is found to cut obliquely across all 

 the beds and is traceable to the northern end of the hill. The 

 following fossils were collected by me from these beds : — 



(a) Fhacops Jamesi, Portl. Mafinesquina expansa, Sow. 

 Orthis calligramma, Dalm., var. Stenopora fibrosa, Goldf. 



(b) AgnosUis agnosiiformis, McCoy Primitia mundula, Jones 

 Encrinurus sexcostatus, Salt. P. mundula var. long a, Jones 

 Barpes, sp. P. mundula var. producta (?), Jones ^ 

 Trinucletis coneentrieus, Eaton (?) Ticrrilepas, sp. (?) 



(c) Amphion pseudo-articulatus, Portl. Plectambottites quinquecostata,'M.cCoY 

 Lichas, sp. Conularia, sp. 



Phacops Jamesi, Portl. Glyptocrinus, sp. (?) 



Orthis calligramma, Dalm. Stenopora fibrosa, Goldf. 



0. crispa, McCoy Nebulipora lens, McCoy (?) 

 Plectambonites sericea, Sow. 



In the Survey Memoir and Collection there are the following 

 additional fossils from this locality : — 



Asaphiis gigas, De Kay Rafinesquina deltoidea, Conr. 



Gheirnrus gelasinosi/s, Portl. Palceaster obtusus, i'orbes 



Cybele verrucosa, Dalm. 



It will be seen on comparison of the lists that the fauna is 

 practically identical with that from Quillia. The slight difference 

 in the fauna of the shaly beds here is to be attributed to the 

 different character of the deposit and of the original physical con- 

 ditions. The abundance of Fhacops Jamesi is a noteworthy feature 

 at both Quillia and Pickardstown. 



2. South of Tramore there is exposed along the coast a series of 

 fossiliferous beds belongcina; to different horizons in the Ordovician 

 system. The lower beds consist of black or dark-grey calcareous 

 slates, which dip at high angles below bedded sandy limestones 



^ Professor Eupert Jones has kindly examined and named the specimens of 

 Entomostraca from these beds.
