. Annual report. New York State Museum; Science; Science. GRAPTOLITES OF NEW YORK, PART 2 267 Syndyograptus pecten sp. nov. Plate 15, figures 5, 6 Description. Rhabdosome of small size, consisting of two stipes from which at regular intervals paired secondary branches (12 or more) are given off. The former have a double curvature, they are at first gently convex for a short distance, and then concave. The angle of divergence of the convex part varies between 200° and 2500 and is typically about 230°; the axil is wide and open. The stipes are narrow (.3 mm at origin) and of nearly uniform width

The angle of divergence of the convex part varies between 200° and 2500 and is typically about 230°; the axil is wide and open. The stipes are narrow (.3 mm at origin) and of nearly uniform width (.5 mm at distance of 25 mm). The secondary branches are straight and ascending, the pairs slightly diverging. The first pair on either side of the center originates from the second theca of each stipe and they follow at intervals of about mm or corresponding to.
