 Lister, pi. 440. f. 283 Donovan, pi. 166. f. 



pi. 10. f. 5. 



Shell flat, of five valves, much resembling the former 

 species ; but is strongly striate in a radiate manner from 

 the lower angle, and crossed by very fine lines ; the angles 

 and points of the valves are more sharp ; and the back 

 valve is flattened on the sides, and brought all the way down 

 to a sharp keel-like edge : it is also smaller, and much 

 more flattened on the upper part, giving the lower end 

 a rather tumid appearance : stalk short, orange red. 



Drifted timber, and the bottoms of ships, v. v. 



3. Lepas sulcata. Furrowed Barnacle. 

 Montagu, pi. 1. f. 6tfood, pi. 12. f. 1. 



Shell flattish, dirty white or brownish, with five valves j 

 the lower-ones with fifteen strong ribs radiating from the 

 lower front angle, that which runs along the front larger 

 than the rest and forming a margin ; the two upper valves 

 forming an oblique parallelogram, being pointed at both 

 ends, like a card placed sideways, and furnished with seven 

 or eight ribs besides intermediate smaller ones ; the back 

 valve flattish, strongly striate longitudinally, wit^a smooth 

 and rather acute edge : stalk very short and dusky : length 

 nearly a quarter of an inch ; breadth nearly as much. 



Found by Montagu, near Portland Island, on theGorgo- 

 nia flabelliformis ; and by Mr. O'Kelly, near Kenmare har-, 

 bour, in Ireland, on a piece of oak bark : we have also 

 taken it on floating timber : very rare. v. v.
