provided with tentacular processes, although when the actinulae are 

 partly dehisced, that gives the appearance of distal processes. 



Distribution. — Thurloe Point, on gorgonids, 8-10 fathoms; South 

 Bay, Cerros Island, also on gorgonids, 10-15 fathoms. 



Suborder GALYPTOBLASTEA 



Family Bonneviellidae 

 Genus BONNE VI ELLA 



Bonneviella minor, new species 



Plate 7, Fig. 26 



Trophosojne. — Zooids arising singly from a loosely spreading stolon, 

 which does not form a veiy definite network. Pedicels short, not as long 

 as the hydrothecae, without annulations or corrugations. Hydrothecae 

 almost tubular, 1.4 mm. long, 0.5 mm. in diam.eter, with a distinctly 

 flaring margin. It has much the appearance of that of B. regia, but is 

 only about half as long and half as wide. 



Gonosome. — Not observed. 



Distribution. — In the channel between Narborough and Albemarle 

 islands, 70 fathoms. 



Family Gampanularidae 

 Genus GAMPANULARIA 



PCampanuIaria emarginata, new species 



Plate 7, Fig. 27 



Trophosome. — Zooids arise singly from a stolon that does not form 

 a network; at times, this stolon seems to form a loose fascicle; total 

 height 4 mm., of which the hydrotheca takes 1.1 or 1.2 mm. Pedicels 

 with no annulations except two, immediately proximal to the hydro- 

 theca. Hydrotheca twice, or nearly so, as long as it is broad, cylindrical 

 in its distal half, gradually rounding to the base. Margin with 12 blunt, 

 distinctly cut teeth, each tooth emarginate. 



Gonosome. — Not observed. 



Distribution. — On Antennularia, La Plata Island, 45-55 fathoms. 



PCampanuIaria gracilicaulis, new species 

 Plate 7, Fig. 28 



Trophosome. — Individual zooids arise from a meandering stolon, 

 which is slender and smooth; the individual pedicels are long and
