250 ARAUCARINEAE [CH. 



large and small cone-scales are recorded by White 1 , Berry 2 , 

 Knowlton, and especially by Hollick from several places on the 

 Atlantic Coastal plain. Knowlton's species Dammarites acicu- 

 laris 3 is probably identical with D. borealis. As examples of 

 smaller forms reference may be made to D. northportensis*, D. 

 minor 5 , and the scales now included in Protodammara. These 

 numerous scales occur as detached specimens and without seeds, 

 but their resemblance to the cone-scales of Agathis and the ana- 

 tomical features exhibited by the lignitic examples described by 

 Hollick and Jeffrey afford strong arguments in favour of ai 

 affinity to Agathis. We have no proof as to the nature of th( 

 vegetative shoots of the parent-plants. Newberry states that ii 

 the Amboy clays the scales occur in association with shoots like 

 Heer's Juniperus macilenta, in some cases, apparently, attached. 

 On the other hand Krasser considered the association of the speci- 

 mens from Moravia, which he called Eucalyptus Geinitzii, with 

 dicotyledonous leaves as evidence of original connexion. 



Protodammara speciosa Hollick and Jeffrey. 



It is probable that these scales 6 are generically identical with 

 the larger forms referred to D. borealis and other species, e.g., 

 D. cliffwoodensis 7 , but until anatomical evidence is obtained a 

 distinction should be recognised. The type-specimens w^ere found 

 at KreiscTierville, Staten Island, New Jersey, in Middle Cretaceous 

 beds, and the species is thus denned: kite-shaped cone-scales 

 from 4 to 6 mm. long by 46 mm. broad above, abruptly narrowed 

 from about the middle to the base (fig. 758, E, F, page 323), 

 rounded, incurved, and apiculate above ; resin-ducts five or more, 

 extending down the lower surface of the limb ; seed-scars three in 

 number, crescentically arranged above the middle and approxi- 

 mately in the broadest part of the scale, with the central one higher 

 up than the laterals. Near the base of a scale there is a single 

 vascular bundle with the xylem uppermost: at a higher level a 

 single strand with reversed orientation is given off and the original
