FIGURE 3. Dushia wijnhoffae Schwartz & Norenburg sp. nov. (A, B, D) Photomicrographs of transverse sections (paratype, USNM 1594813); (C) photomicrograph of anesthetized animal with cephalic furrows reflected back to expose ciliated glandular ridge; the specimen was destroyed after examination and not extant. (A) Organization of the cerebral ganglia region showing dorsal and ventral ganglia and positions of Bürger type III cells, neurocord cell and neurocord. (B) ×40 magnification of Bürger type III cell and neurocord cell in A. (C) Ciliated and gland cell ridge of cephalic furrow marked by arrow heads. (D) Transverse section through glandular ridge in C, arrow heads mark the cells with elongated cilia, asterisks indicate gland cells. Scale bars: A, B, D = 100 µm, C = 500 µm. Abbreviations: b3, Bürger type III neural cell; cf, cephalic furrow; lnc, lateral nerve cord; nc, neurocord cell; vg, ventral ganglion.Published as part of Hookabe, Natsumi, Schwartz, Megan L., Kajihara, Hiroshi & Norenburg, Jon L., 2019, Molecular systematics of the heteronemertean genus Dushia (Nemertea Pilidiophora), with descriptions of D. wijnhoffae sp. nov. and D. nigra species complex comb. nov., pp. 333-358 in Zootaxa 4691 (4) on page 343, DOI: 10.11646/zootaxa.4691.4.2, http://zenodo.org/record/352735
