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. f. 6— JVood , pi. 12. f. 1. 
Shell flattish, dirty white or brownish, with five valves, , 
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 sere* 
or eight ribs besides intermediate smaller ones ; the bad 
valve flattish, strongly striate longitudinally, with 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 the Gorge* 
nia flabelliformis j and by Mr. O’Kelly, near Kenmare har* 
hour, in Ireland, on a piece of oak bark: we have also 
taken it on floating timber: very rare. v. v.
