. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. Figure 2. Internal anatomy of Lucernaria janetae. n. sp. (A) Transverse section through peduncle, showing four septal muscles. (B) Detail of a septal muscle. (C) Subumbrellar surface, showing U-shaped vesicles and slender gastric filaments. Scale bars: A = 2 mm; B, C = mm. more wedge- than goblet-shaped. Eight clusters of second- ary tentacles; calyx not notched between each cluster. Sec- ondary tentacle clusters with fewer members; tentacles rel- atively thicker, shorter, not capitate; opaque, round head at distal end not demarcated from stalk. Primary tentacles not visible. Larger juveniles not attached to adult. Calyx width of larger of two specimens 3 mm. depth 3 mm; peduncle length 4 mm; smaller specimen calyx width 3 mm. depth 4 mm, peduncle length 2 mm. Color of both uniformly white. Calyx shape and proportions similar to those of adults (Fig. 3A): calyx goblet-shaped with rounded prox- imal end. Inter- and per-radial notches equal in depth, relatively shallower than in adults but clearly divide calyx into eight arms. Eight clusters of capitate secondary tentacles (Fig. 3A. C); compared to adults, clusters with fewer members. Small, oval, opaque primary tentacles (Fig. 3C); primary tentacles nodule-like, raised between secondary tentacles. No nematocysts found in primary tentacles; secondary tentacles with sparse, relatively. I Figure 3. Morphology of juvenile specimens of Luccrnunu iiinctuc. n. sp. (A) One of the two larger juveniles; general shape and proportions as in adults. Scale bar = I mm. (B) Smallest juvenile, attached to basal end nt an adult. Scale bar = 1 mm. (C) Primary tentacles (arrows) on specimen in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. );
