number of 52 forms, and it was R. R. Gurley's intention to mono- 

 graph these graptolites. The work was left uncompleted and is 

 now put in good order by Bassler. The geologic horizon appears 

 to be the lower portion of the Lockport dolomite. But live of the 

 species are found in lower horizons, four in the Rochester shale 

 (Dictyonema retiforme, D. polymorphum, Inocaulis plumulosus, 

 Acanthograptus walkeri) and one in the Upper Clinton ( Cyclo- 

 graptus rotadentatus). c. s.

 Dr. W. S. Bruce; by G. W. Lee. Trans. Royal Soc. of Edin- 

 burgh, 47, 1909, pp. 143-186, pis. 1, 2. — From a bed of limestone 

 (Cape Cherney) on the west coast of southern Nova Zembla, in 

 lat. 70° 49' and long. 56° 37' was collected a most interesting 

 fauna of over 90 species. These are of the Productus gigantens 

 horizon, here rich in brachiopods, foraminifers (7 species), corals 

 and mollusca (dwarfed forms). No cephalopods are present. The 

 fauna is "very closely allied to that of the Giganteus zone of the 

 Urals and Central Russia, which is practically the same as that of 

 Western Europe." Carruthers studied the corals and in regard 

 to the horizon states that it is " between the base of the Upper 

 Carboniferous and the top of the Lower Carboniferous of the 

 Russian classification." c. s.
