 SALL, Ann. and Mag. of Nat. Hist. Vol. vn. PI. x. fig. 5, PHILIPPI, 

 WIEGM. u. EKICHS. Archiv, vin. 1842. Taf. I. fig. 3. Turbinate shells are 

 often found incrusted with a greyish-brown firm covering, difficult to remove: 

 this is ,the common body to which the several polyps, some millimeters long, 

 are attached, which have of late years been described by different observers. 

 QUATREFAGES found his specimens on the shells of Turbo and Buccinum, in 

 which the hermit-crab (Pagurus) had taken up his abode ; so also EASIER 

 previously, natuurk. Uitsp. I. Tab. in. fig. 5. According to QUATREFAGES, 

 it is by no means established that all the above-mentioned names refer, as 

 VAN BENEDEN determines, to the same animal. 



Coryne GrAERTN., Stipula SARS, Syncoryna EHRENB. Polyps 

 with scattered tentacles, nodiferous or globose at the tip. Polypary 

 papyraceous, subramose, with polyps at the extremities of the 

 tubes, not retractile within the tubes. 



The name Coryne of GAERTNER, PALLAS Spicileg. Zool. Fasc. x. 

 1774, pp. 36, 40, 41, has by later writers been perversely given to 

 other kinds, and the original typical species been named Syncoryne.
