JUGLANDALES. Io9 Descriptio_.--Leaves variable in size, i.I. cm. to 5 cm,.in length by o. 4 cm. to 2 cm. in breadth, ovate !anceolate in outline with an obtusely pointed apex and a cuneate, slightly decurrent base. Margin divided into from g to 4 sligbtly aquiline, rounded, obtusely pointed lobes, the intervening rounded sinuses cut about half way to the midrib. Secondaries craspedodrome, one to each lobe. In the larger leaf there .is a second secondary some distance below the one which traverses one of the lobes, and, while this is not visible throughout its length, it was probably camptodrome as in the leaves 04 the modern Comptonia. It is difficult to understand on what ground Prof. IKeer founded hls two species pafvuhz and parvifolic_ unless it was because they were supposed to have come from different geological horizons. He compares both to the European Coanptonia ce_i*tgensis A1. Br., although their resemblance to that species, as a naatter of fact, is not very close. The two are exactly similar, as is the Rheas included in the foregoing synonymy, except as to size. The Raritan specimen which Newberry identi- --// fled as parvula is closer to parv_folia, which fact is noted by the latter author, who presumably hesitated to refer a Cretaceous leaf to a species of the Miocene, as these Arctic deposits were thought to be at that time. The writer has elsewhere (loe. cit.) called attention to the probability of Heer's specimens having come from practically the same horizons, so that there are no valid reasons for maintaining their fancied distiuctness. The earliest leaves of the modern Comptonia peregri_a (Linn6) Coulter usually are very similar to this fossil species. These latter might be considered as the abbreviated leaves, so common in seedling plants and hence without phylogenetic meaning, or they may be considered as representing the normal leaves of these ancient Comptonia plants. The first assumption seems doubtful, not only because of the perishable nature of seedling leaves in general, but because it is unusual for them to become detached and fossilized, and it would be a rather singular coincidence for this to have occurred in New Jersey, Greenland, and Europe only once and at the same geological horizon. Furthermore, no other species of Comptonia are known from either the Raritan clays, or the Atane and Patoot schists, from which they 8 PAt, NEW JERSEY GEOLOGICAL SURVEY

It would seem that the conclusion is reasonable that these are the normal leaves of the earliest known Comptonias, and that the modern seedling leaves are truly ata- •vistic. The remains of this species are scanty, the Raritan occurrence being based on a single specimen, and all are very similar to the contemporaneous Comptonia an_iq_¢a Nilsson, described about se_enty-five years ago from .Sweden.
