GWILLIAM with picro-indigo-carmine following bulk staining in Grenacher's borax carmine, or with alum hematoxylin and eosin. I would like to express my gratitude to the Director and Staff of the Friday Harbor Laboratories of the University of Washington for a grant which made residence at the Friday Harbor Laboratories possible for a period of seven months. My thanks are also due to the Department of Zoology, University of California, Berkeley, for support and encouragement over a period of several years. Dr. Ralph I. Smith and Dr. Cadet Hand have aided in many important ways, not the least of which was a critical reading of the manuscript. Their interest and criticism is deeply appreciated. Dr. T. H. Bullock has been kind enough to read the manuscript. His criticisms and suggestions have been very helpful and are gratefully acknowledged. I MM. MS FIGURE 2. Cross-section through the stalk of Haliclystns auricula. SC, stalk canal; MS, stalk muscle; M. mesoglea. RESULTS Musculature of Haliclystns It is possible to divide the muscles of Haliclystns into three categories associated with particular regions of the body. The stalk possesses four interradial muscular bundles (Fig. 2) embedded in the mesoglea which continue distally into the sub- umbrellar ectoderm as eight perradial sheets that fan out over the subumbrellar surface (Fig. 3). Proximally. the stalk muscles are inserted at the pedal disc over a rather wide area. There is also a marginal muscle (subumbrellar) which borders the margin of the calyx (Fig. 3 ) and is only partially embedded in the mesoglea. This latter muscle is interrupted at the arms and so consists of four perradial and four interradial segments. In addition, arm tentacles, gastric tenta- cles, manubrium, and anchors are provided with muscle fibers. The principal.
