. Bulletin - United States National Museum. Science. 63 Figs. 01-63.—Stolonica styeliformis, new species. 61, Left and richt sides of eody of zooid. x 62, dorsal tubercle x 15. 63, gonads. x terior end and the atrial a little way back on the dorsal side. Colony consisting of a more or less dense cluster of zooids, which, though attached to the object on which they grow by the posterior end only, are often so crowded together that the posterior parts of their bodies are in close contact and adhere together, but they do not fuse, and can be torn apart without injuring the test. The anterior part at least of the body of each zooid is free and separate from adjacent zooids. The largest specimen (No. 130), (Cat. No. 5995, ), though evidently only a part of a colony, completely surrounds a section of the stem of an alcyonarian for a length of about 60 mm. and consists of about 100 closely placed zooids, mostly of fairly uniform size (14 mm. to 16 mm. long and 6 mm. to 7 mm. in dorso- ventral diameter). Another colony (No. 113) is similar but more irregular, and has zooids of less uniform size. In neither of these colonies are the zooids mature. In specimens from stations D5174 and D5555 the zooids are larger, sometimes reaching 23 mm. or more in length, and are fully adult. The}' are generally less closely crowded, their bodies being separate for the whole length; the posterior end is often narrowed into a short pedicel-like extension.
