92 PALEOZOIC PALEONTOLOGY. 
back of the Nearpass quarry bluff it forms a continuous outcrop for 
half a mile or more, and is frequently met with further south. The 
entire thickness of the formation has never been observed, but it is 
estimated as twenty feet, more or less. 
The fauna of the Becraft limestone is closely allied to that of the 
New Scotland beds, many species being common to the two forma- 
tions, although some forms identified from one formation have not 
been observed in the other. Because of this conspicuous community 
of species in these two formations, their faunas have not been sepa- 
rated in the descriptive part of the present report, but are all de- 
scribed together. 
Locality 2 A*'-—The only locality where the fossils of the Becraft 
limestone have been carefully collected is in the low ridge back of 
the Nearpass quarry bluff. Fossils are abundant in the formation, 
wherever it occurs, but they are always so firmly imbedded in the 
hard, cherty matrix that it is difficult to collect them. In the collec- 
tions made from the Nearpass section the following species have 
been identified : 
. Streptelasma strictum Hall. 
. Stropheodonta becker Hall. 
. Stropheodonta sp. undet. 
. Strophonella punctulifera (Con.). 
. Leptena rhomboidalis (Wilck.). 
. Rhipidomella oblata (Hall). 
. Schizophoria multistriata (Hall). 
. Uncinulus vellicatus (Hall). 
. Rhynchotrema formosum (Hall). ? 
. Smrifer cyclopterus Hall. 
. Meristella levis (Van.). 
. Actinopteria sp. undet. 
. Lichas pustulosus Hall. 
. Homalonatus vanuxemi Hall. 
5. Phacops logant Hall. 
. Dalmanites pleuroptyx (Green). 
17%. Beyrichia sp. undet. 
With the exception of the two trilobites, Lichas pustulosus and 
Homalonatus vanuxemi, and the brachiopod, Schizophoria multi- 
striata, the species represented in the Becraft limestone fauna are 
present, also, in the fauna of the New Scotland beds. There is, 
however, some difference in the proportionate number of individuals
