214 NOTES ON SAGAKTIID^ AND ZOANTHID^ FKOM PLYMOUTH. 



The whole colony bears a strong resemblance to that figured by 

 Haddon and Shackleton, Hcvis. Brit. Actinim, Pt. II, PI. LVIII, Fig. 37. 



Polyps stout, contracting somewhat toward the summit, where they 

 again enlarge. Margin rounded, with 16 to 18 well-developed ridges. 

 Disk and mouth not \dsible. 



Tentacles difficult to enumerate, almost all being retracted. Thirty 

 were visible in one large polyp, fairly stout, and dull white in colour. 

 Colony sand colour. 



A transverse section shows the ectoderm and nematocysts, encircling 

 sinus and canals, endoderm, etc., to be as described by Haddon and 

 Shackleton. The incrustations, consisting of sand grains, spicules, etc., 

 were, however, more numerous than in their specimens. 



The specimens described by the above-mentioned authors were 

 obtained oil' the coast of Kerry, Ireland, in 70-80 fathoms. The 

 Millbay pit, from which the present colony was probably obtained, 

 has a depth of from 12 to 17 fathoms.
