 Balanus conoides. Montagu Test. p. 12. 



Inhabits the shore at Weymouth on Lepas anatifera. Dono- 

 van. 



This species is said by Mr. Wood, to be very nearly allied to 

 L. angustata, but has faint transverse, as well as longitudi- 

 nal striae on the valves ; and Mr. Donovan has represented 

 the three posterior valves to be much larger than the others. 

 The figure represents a shell about a quarter of an inch in 

 diameter, and of a purplish colour. 



angustata. 9. Shell semi-ovate, with the valves 

 longitudinally striated; aperture small and 

 much contracted.

 Shells half an inch in diameter, and about two-thirds as high, 

 and, owing to their growth in thick clusters, they are often 

 much elongated ; the valves are nearly united at top, and 

 separated only by narrow groove-like interstices ; the colour 

 is dingy white, becoming darker with age, and longitudinally 

 striped with purple. 



costata. 10. Shell sub-conical, with equi-distant 

 ribs diverging* from the aperture; operculum 

 sharp pointed.

Found on a piece of rock at Pembroke, by Mr. Adams. Do-
