258 MESSES. E. HEEON-ALLEN AND A. EAELAND ON THE 



occur at Stns. 5, 12, and 21. At Stn. 14, a single example of the Batsch type was found, 

 in which the produced neck was exceptionally thick and studded with spines, a form of 

 growth usually found in deeper water. Bicamerate specimens are widely distributed at 

 many Stns., and at Stns. 6, 16, and 19 were the sole representatives of the species. In 

 many instances, these bicamerate individuals were of large proportions, indicating that 

 they were not young shells, but a distinct local variety in which growth was normally 

 arrested at this stage. 



217. Nodosaria scalaris, var. separans, Brady. 



Nodosaria scalaris, var. separans, Brady, 1881, PC. p. 511, pi. lxiv. figs. 16-19. 



Millett, 1898, etc., FM. 1902, p. 520, pi. xi. figs. 11, 12. 



2 Stations. 



No perfect examples were found, but an isolated final chamber at Stn. 4, and at 

 Stn. 20 two final chambers connected, which had evidently been attached to the earlier 

 portion of the shell by a stolon-tube. 



218. Nodosaria proxima, Silvestri. (New to Britain.) 



Nodosaria proximo, O. Silvestri, 1872, NFVI. p. 63, pi. vi. figs. 138-147. 

 „ Brady, 1884, FC. p. 511, pi. lxiv. fig. 15. 



Fornasiui, 1888, TP. p. 149, pi. iii. figs. 10, 11. 



2 Stations. 



Bilocular Nodosarise referable to Silvestri's species (inasmuch as the initial chamber 

 is larger than the succeeding one) occur rarely at the two Stns. In dredgings like 

 these, where N. scalaris abounds, the question of their separate identity is open to 

 question. 



219. Nodosaria raphanistrum (Linn6). 



Nautilus raphanistrum, Lirme, 1788, SN. p. 3372. No. 15. 



Nodosaria raphanistrum, Jones, Parker, & Brady, 1866, etc., MFC. 1866, p. 50, pi. i. figs. 6-8. 



1 Station. 



Two small specimens, one pyritised, probably derived fossils from Gault or Lias, 

 though their occurrence in Loch Sunart is hard to explain. 



220. Nodosaria obliqua (Linn6). 



Nautilus obliquus, Linne, 1767, SN. p. 1163. No. 281 ; 1788, SN. p. 3372. No. 14. 

 Nodosaria obliqua, Brady, 1884, FC. p. 513, pi. lxiv. figs. 20-22. 



6 Stations. 



Very rare ; the specimens small and weakly sulcate, often distorted, the best at 

 Stn. 20. At Stn. 23 the individual was sulcate on the initial chamber only.
