including species new to that of Britain. 385 



Pecten fuci*, Gmelin. P. Landsburgii, Forbes, Wern. Mem. 



vol. viii. 



Procured on rocky ground, east of Cape Clear (forty to forty-five 

 fathoms), by Mr. MacAndrew, who remarks, that " it is a common, 

 though rather deep-water species. I have obtained it at ScilJy, Isle 

 of Man, Mull of Galloway, Glenluce Bay, Clyde and Hebrides — 

 generally adheres to stones ; only at Oban have I found it attached 

 to the Fucus." 



Pecten similis, Laskey, Wern. Mem. vol. i. p. 387. pi. 8. fig. 8. 

 Numerous valves were dredged from forty- five fathoms off Cape 

 Clear by Mr. MacAndrew, who finds it " an abundant deep-water 

 species from Scilly to Zetland." This species was noted at the sug- 

 gestion of Professor Edw. Forbes as probably synonymous with P. 

 Imvis, in my Report on the Invertebrata of Ireland. 



Area raridentata, SearlesWood in Charlesworth's Mag. Nat. Hist. 



vol. iv. p. 232. pi. 16. fig. 4. 



A living specimen, and a valve of this Area, were obtained with 

 the last species. It is a crag shell. Mr. MacAndrew procured it 

 alive for the first time off the island of Skye in the summer of 1 845 . 



Near a cuspidata, Olivi (sp.). 

 An imperfect specimen was taken with the preceding two species. 



Lucina lactea, Poli (sp.), Lam. 

 Procured off the south-west coast by Mr. MacAndrew — off Balti- 

 more Harbour, thirty fathoms ; and from twelve to fifteen fathoms in 

 Bantry Bay. 



Tellina balaustina, Linn. 

 Two valves of this species, as determined by Mr. G. B. Sowerby, 

 were dredged on the occasion already alluded to in Birterbuy Bay 

 by Mr. Barlee. It has not before been noticed as inhabiting any of 

 the coasts of the British Islands. 



Montacuta oblonga, Turt. Brit. Biv. p. 61. pi. 11. figs. 11, 12. 

 Taken in fine sand from thirty fathoms between Baltimore Har- 

 bour and Cape Clear by Mr. MacAndrew, who adds, " frequent in 

 company with fine live specimens of Eulima subulata." 



Botrylloides albicans, Edwards, Ascid. Compos, p. 88. pi. 6. fig. 2. 

 July 16, 1846. — I found this species attached to the under side of 

 a stone in a pool between tide-marks at Springvale, county of Down. 

 It was likewise attached to Fuci (F. vesiculosus, &c.) growing in the 

 rock-pools, and was in much smaller masses than the following spe- 

 cies ; generally but one system of individuals existed in each mass. 



* Since the above note was sent to press, I have learned from Mr. Barlee 

 that lie obtained this species in Birterbuv Bay (co. Galway) in the summer 

 of 1845.
