the total height of which is about ten feet, was cut clown some 

 years ago in searching for cetotolites and other cetacean remains, 

 when a band of nodules and fragments of whales' bones, mixed 

 with upper bed shells, was reached, but the strata then becoming 

 hard, and apparently unproductive of fossils, the remaining 

 portion was not uncovered. As I had seen lower bed shells in 

 close proximity to this place, I employed a man to cut down the 

 whole of the bank, and thus give a perpendicular section. The 

 result was gratifying. The nodule band, which is only a few 

 inches in width, proved to be the actual division between the 

 upper and lower deposits. Above it, the most characteristic shells 

 of the upper zone were found in profusion, beneath it, the species 

 obtained were, almost without exception, those peculiar to the 

 lower zone. 



In the topmost strata, in addition to many other characteristic 

 species, numerous and very fine examples of the following occur : — 

 Solen sordidus Zenatiopsis angustata 



Dosinia Johnstoni Nucula tumida 



Barnea tiara Leda acinaciformis 



Mactra axiniformis Crassatella oblonga 



Hamiltonensis Cytherea paucirugata 



The inferior beds are not nearly so well represented here as at 

 Clifton Bank, and other places lower down the creek, the shells 

 being fragile, and not very abundant. The following, amongst 

 other typical forms, were collected immediately beneath the 

 nodules : — 

 Yoluta strophodon Dimya dissimilis 



antiscalaris Leda vagans 



Conus Ralphii Trigonia semiundulata 



Terebratula vitreoides Lucina araneosa 



The elevation of the nodule band is 410 feet above sea level. 

 Farther up the stream, and therefore at a higher level, only the 

 superior beds are in sight. From a fine outcrop of these (marked 

 "c" on map), a large collection of fossils has been made, chiefly by 

 Mr. McDonald, the result being the discovery of several new 

 species peculiar to the upper zone, as — 

 Voluta Masoni Eligmope Dennanti 



Siphonalia spatiosa Pecten subconvexus 



^assa sublirella Triton ovoideus 



Pelicaria coronata Pectunculus convexus, &c. 



The fossiliferous strata crop out almost continuously on the 

 banks of Muddy Creek between this spot and the falls, but wher- 

 ever examined, they are found to consist of either the upper or 

 lower beds, according as they lie above or below the level of the 

 nodule band.
