CRETACEOUS CONIFERALES 51 
Locality: Androvette pit. Collected by E. C. Jeffrey and Arthur 
Hollick. Specimens in Jeffrey collection, Cambridge, Mass. 
Genus SPHENASPIS gen. nov. 
Sphenaspis statenensis sp. nov. 
Plate ro, figs. 22, 23; Pl. 26, figs. 2-4 
Remains consisting of cone scales, wedge-shaped below, somewhat 
peltate above; surface of the pelt hollowed in its upper part, the 
lower lip of the excavation conspicuously projecting as an 1. 
cuspidate process; internal structure showing an upper and a low 
series of 1. bundles, the latter accompanied by resin nl 
the phloem sides of both series surrounded by a thick zone of trans- 
fusion tissue. 
This type of cone scale was found somewhat sparingly in the 
lignitic debris of the Androvette pit. “The characteristic wedge- 
shaped base and projecting cuspidate process on the lower surface 
are well shown, X 10, in the side view represented by fig. 23, Pl. то, 
which resembles the dental alveolus of a sea urchin. The hollowed 
outer surface is somewhat comparable to that of Sequoia and Geinitzia, 
but it lacks the process at the bottom of the depression and is clearly 
differentiated by the projecting cuspidate rim of the lower lip of 
the depression. Figure 22, Pl. го, shows the appearance, X то, 
of the inner basal portion and part of the upper surface of the scales, 
viewed from in front and slightly from above. 
A transverse section of the scale, X 15, 15 shown in fig. 2, Pl. 26. 
A series of numerous bundles stretches across what appears to be the 
upper side. On the lower there are fewer bundles and a number of 
large cavities which represent more or less disorganized resin 
canals. Figure 3, Pl. 26, represents a transverse section, X 15, at a 
higher level, in an inverted position to that shown in the previous 
figure. There is now a space in the center which represents a trans- 
verse section of the terminal depression. Figure 4, Pl. 26, is a por- 
tion of the latter section, X 100, showing one of the upper series of 
bundles, in which the phloem side is surrounded by a thick zone of 
transfusion tissue. This condition, which is found in both series of 
bundles, is a clear indication of araucarineous affinities. On account 
of their characteristic wedge-like shape and somewhat peltate ends 
we have adopted for these scales the generic name Sphenaspis, and 
a specific name which indicates the place where they were discovered.
