The chief distinction between T. plialamiea and T. JlaheUaris, 

 which are, perhaps, hardly distinct specifically, consists in the 

 greater length and slenderness of the tubes in T. phalangea, and 

 their far greater tendency in that form to assume a serial arrange- 

 ment, the series, when the zoarium is lobed, appearing to run 

 laterally from a mesial line down the middle of each lobe or division 

 (as in T. serpens). Prof. Smitt appears to have included both 

 forms under T. flabellaris, as there is little doubt Fabricius did, and 

 they are probably not far wrong. 



3. Tubulipora serpens, Linn, (Plate XXII.) 

 Zoarium composed of curved strap-shaped lobes or branches, 

 which divide more or less dichotomously ; decumbent, but usually 

 very slightly attached ; ceUs disposed in transverse series, diverging 

 on either side from a mesial line.
