SOME FOSSIL SEEDS FROM THE UPPER PALAEOZOIC ROCKS OF THE WERRIE BASIN, N.S.W. By A. B. Walkom, D.Sc. (Plate xix.) [Read 27th November, 1935.] The seeds described in tliis paper were collected by Mr. S. W. Carey during the course of his geological investigation of the Werrie Basin (Carey, 1934). They include specimens from three distinct Series, viz.: (a) Kuttung Series, (b) Greta Coal Measures, (c) Newcastle Coal Measures. The seeds from the Kuttung Series were collected from several horizons within the Glacial Stage of that Series and represent a variety of types. This variety of seed types is interesting in view of the limited number of species of which the vegetative organs are known in the Kuttung Series. From the upper part of this Series (part of Volcanic Stage, and the Glacial Stage) the following plants have been described: Archaeocalamites radiatus, Lepidodendron sp., Rhacopteris ovata, R. inter-media, R. Roemeri, R. septentrionalis, R. Wilkinsoni, ? Noeggerathia sp., Cardiopteris cf. frondosa, SpTienopteris Clarkei, ? Sphenopteridium cmieaUim, Adiantites (?) mbustiis and RliacopliylUira diversiforme. These plants have been recorded from the Upper Kuttung Series in areas south of the region investigated by Mr. Carey. I have no record of the extent of the collections of vegetative organs made by Mr. Carey from the Kuttung Series in the Werrie Basin. Attention has been drawn in other parts of the world to the numerical excess of seeds over vegetative organs in Upper Palaeozoic rocks. It would appear that collectors in the past have paid little attention to the seeds which are almost certainly obtainable in the Kuttung Series in association with the vegetative remains. Mr. Carey has shown that seeds are quite abundant on a number of horizons in the Werrie Basin and future collecting in other areas may be expected to reveal the presence of a variety of seeds. The seeds are preserved as impressions, and little information is available regarding their structure. It is, however, worth while recording their occurrence as a guide to future collectors. (a) Seeds from the Upper Kuttung Series. Trigonocarpus (?) ovoiDEUs, n. sp. PI. xix, fig. 1. Impressions of ovoid seeds, broadest near base, gradually narrowing towards apex where there is a short narrow projection. The impressions are 7-8-5 mm. long by 5 mm. broad, the apical projection 0-5-1-0 mm. long. There are some fine vertical striations, and indication of one or two vertical wrinkles. The edge (for a breadth of about one-third of a millimetre) appears solid. M
