1898-1902. No. 32.] FOSSIL FAUNAS FROM SERIES B. 15 



Cladopora rectilineata is known from the Decker Ferry of New 

 Jersey and from the Keyser of Maryland. On an excursion in Maryland 

 in May 1913 in the company of Professor SCHUCHERT I had an oppor- 

 tunity of collecting fine specimens of this form, and these have now been 

 of great value for comparison with the Arctic ones. 



Occurrence: B, upper part, point north of the beautiful valley.

Only a very small portion of a thin expansion, with the characters of 

 the surface beautifully preserved is seen of this characteristic species. The 

 tubes with their 12 septa show a diameter of 1 mm. and the septa not 

 seldom unite with those of the adjoining tubes across the interstitial space. 



There can be no doubt as to this identification. In Europe the 

 form generally occurs in rocks of Wenlock age, in Norway however, 

 it has been found by Professor KLER extending high in Ludlow. In 

 America Thecia swinderenana is cited from the Niagaran. 



Occurrence: B, middle part, between Reindeer Valley and 

 valley south of Borgen. 



Syringoporidae. 



Syringopora GOLDF. 



Syringopora sp. 



PI. VI, fig. 1-2. 



A specimen of dark grey, somewhat crystalline limestone contains 

 some imbedded fragments of colonies of a Syringopora, too small for 

 any certain identification. At one place on the face of the rock the basal 

 portion of a colony can be seen, corallites here growing in a flat expansion 

 from which they then bend upwards and become erect and subparallel,
