DISCOVERY REPORTS 



Remarks on the specimens 

 deep furrow between the two (dorsal) secondary autozooids, then again it bends a Httle 

 inwards to end in the basal wall of an eleventh autozooid (the primary polyp), which has 

 been displaced to the inner side of the whorl (text-fig. 3, 7). Autozooid bodies 2-2-5 cm., 

 tentacles 1-5-2 cm. long. Siphonozooids evidently placed like those of 4, but all but 

 invisible. Typical magniflora. 



6, total length about 100 cm. 



Rachis bowl-shaped with 11 marginal autozooids and one a little smaller (primary 

 polyp ?) near the centre of the whorl. The axis enters the centre from below and disappears. 

 Siphonozooids numerous on the lower side of rachis, not visible within the whorl of 

 autozooids. Tentacles retracted. 



7, total length about 107 cm. 



Rachis like that of 6, surrounded by a whorl of 10 autozooids. In the central field there 

 are two additional autozooids of the same size. Siphonozooids only visible on the lower 

 part of rachis, some of them with extended tentacles. Both in 6 and 7 the stem is ex- 

 ceedingly slender and flexible, the upper part of the axis just below the rachis does not 

 attain a diameter of i mm., and shortly above the holdfast it is only 1-5 mm. thick.

99-161 6 specimens. 



I, total length 31 cm. 



Specimen rather 'fleshy', but with a thin axis, measuring just below the cluster 

 0-7 mm., shortly above the holdfast about x mm. thick. Rachis basally laterally com- 

 pressed by contraction. Autozooids in 3-4 quite irregular whorls, young and small 

 autozoids budding irregularly between the large ones. Although rather strongly con- 

 tracted the larger autozooids with body lengths up to 20 mm. and tentacles 8-10 mm. 

 long. Siphonozooids in all interspaces between the autozooids, with retracted tentacles. 



2 and 3, total length in both about 37 cm. 



Both specimens rather fleshy. Axis just above the holdfast about 2 mm., below the 

 rachis i mm. thick. Autozooids with body lengths up to 4 cm., tentacles to 2 cm. Both 

 the tissues of the polyps and those of the wrinkled and folded stem and holdfast are not 

 distinctly contracted but are remarkably flaccid. 2, has some 37 autozooids, the 9 lower- 

 most of which constitute a whorl round the bowl-shaped basal part of rachis. 3, has 

 12 autozooids in the basal whorl of the ample tassel. Both specimens link antarctica 

 together with rigida (cf. Kiikenthal and Broch 191 1, PI. 26, fig. 16). 



4, total length 43 cm. 



The specimen is fleshy, the coenenchyma wrinkled and folded although seemingly not 

 very contracted. Axis 3 mm. thick just above the holdfast, 1-8 below the cluster. Rachis 

 was bowl-shaped below the cluster, but is now (by preservation?) strongly wrinkled. 

 The axis enters the rachis in the centre from below and disappears. The cluster has more 

 than 40 autozooids with bodies up to 4 cm. and tentacles mostly 1-5-2 cm. long. Young 

 polyps and new buds irregularly scattered among the fully developed autozooids. Sipho- 

 nozooids crowded in all interspaces between the autozooids as well as on rachis below the 

 cluster, none with extended tentacles. 



5, total length 46 cm. 



Rather slender, axis just above the holdfast 1-1-5 mm., just below the cluster | mm. 

 thick. The basal part of rachis is nearly bowl-shaped. The axis enters it centrally from 

 below, but here it bends and follows one (dorsal) side ending in the basi-dorsal wall of 

 one (primary) autozooid. There are 8 fully developed secondary autozooids in one simple 

 whorl along the brim of the bowl-shaped rachis ; a small ninth bud diametrically opposite 

 the primary polyp. This has been pushed to the inner side of the whorl (the cluster 

 almost coincides with text-fig. 3, 7). The autozooids are rather inflated and show body 

 lengths up to 3 cm., whereas the rather contracted tentacles at most are 1-2 cm. long. 

 Siphonozooids indistinctly observed in all spaces between the autozooids. Typical 

 magniflora. 



6, total length 88 cm. 



Very slender, axis near the holdfast 1-5 mm., just below the cluster J mm. thick. 

 Autozooids contracted but not externally wrinkled, body up to 2 cm., tentacles up to 

 5 mm. long. Siphonozooids in all interspaces between the autozooids, almost invisible, 

 also crowded on the under side of the bowl-shaped rachis. 10 autozooids in a simple 

 whorl and an eleventh displaced to the inner side on one (the dorsal?) side. The cluster 

 agrees with 5 from St. 366 (text-fig. 3, 7) but the terminal part of the axis is buried in 

 the tissues of the rachis.
