Plate XXI. fig. 3. 



STEMS short, sparingly branched, from | to 1 inch in 

 height, pretty regularly marked by distinct annulations, 

 which extend to the creeping stolon ; CGENOSARC orange, 

 deepening in tint towards the base, expanding into a 

 collar immediately below the polypites ; POLYPITE very 

 large, measuring, in full-sized specimens, about 5 lines 

 from tip to tip of the extended tentacles, body scarlet ; 

 GONOPHORES oval, on short, erect, branched peduncles ; 

 each gonosac with 4 well-marked tentaculoid tubercles on 

 Us summit ; the peduncles and spadix scarlet. 



" A BEAUTIFUL little zoophyte, conspicuous by the bright 

 colour and large size of its polypes." (Allman). The an- 

 nulatiou, which extends pretty uniformly throughout the 

 stem, is remarkably Avell-defmed. 



Hab. " Attached to the bottom of rock-pools at extreme 

 low-water spring-tides, Shetland" (G. J. A.). 



6. T. ATTENUATA, Allman. 



"Notes on the Hydroida," Ann. N. H. for July 1864. 



STEM 3 or 4 inches high, slender, obscurely corrugated, of a 

 light straw-colour, very irregularly branched, with the 

 branches given off at a wide angle ; POLYPITE supported 

 on a collar-like expansion of the coenosarc, the oral ten- 

 tacles about one-third as long as the aboral, the body 

 deep vermilion between the two tentacular verticils, and 

 thence becoming paler towards the enlarged base ; GO- 

 NOPHORES (male) on short, erect, branched peduncles, 

 usually 5-8 in a cluster ; tentacular appendages long.
