126 Mr, Jeffreys’ Synopsis of British Species of Teredo. 
13. 7. fimbriata +, n. s. 
T. palmulata, Forbes and Hanley, but not of Lamarck or Philippi. 
Hasrrat: in teak-wood, Leith (Jeffreys). 
The minute description of this species which is given in the 
‘History of the British Mollusca’ makes it unnecessary to add 
anything to it; but I may remark that the front margin of the 
pallet is fringed, as in 7’. pennatifera and bipennata, and that the 
valves are more nearly allied to T. fusticulus than to the T. pal- 
mulata of Philippi. 
14. 7. pennatifera +, Blainville. 
Hasrtat: in floating wood thrown up on the coast of Guernsey 
(Lukis); Beachy Head (Dennis). In France it has occurred 
under similar circumstances at Cherbourg. 
15. 7. bipennatat, Turton. 
T. carinata (partim), Gray. 
Hasrrat: with the last. 
This species requires further investigation, because of the 
similarity of its valves to those of 7. malleolus, and of its pallets 
to those of 7. pennatifera. The former appear, however, to pre- 
sent a difference in being more arched and solid than in T. mal- 
leolus, with the anterior auricle larger and having more striz, as 
well as in the posterior auricle being usually smaller; and the 
latter in having a much shorter and thicker stalk than in 7. 
pennatifera, which is not annular or tracheiform as in that spe- 
cies, as well as in the lateral filaments being shorter and less 
slender. 
Observation.—The species distinguished by a + may not be 
strictly indigenous, but occasionally or accidentally visiting these 
coasts. I have given only the localities which occurred to myself 
or were communicated to me by scientific friends, haying in 
every instance examined and verified the species, 
Exotic Species.
