276 MESSES. E. HERON-ALLEN AND A. EARLAND ON THE 



295. Pulvinulina auricula (Fichtel & Moll). 



Nautilus auricula, var. a, Fichtel & Moll, 1798, TM. p. 108, pi. xx. figs, a, b, c. 

 Pulvinulina auricula, Brady, 1884, FC. p. 688, pi. cvi. fig. 5 a, b, c. 



12 Stations. 



Fairly widely distributed and sometimes common ; the only noticeable feature is the 

 fact that at Stn. 11 all the specimens were extremely small, those at the other Stns. 

 showing normal to large. 



296. Pulvinulina oblonga (Williamson). 



Nautilus auricula, var. /S, Fichtel & Moll, 1798, TM. p. 108, pi. xx. figs, d, e,f. 

 Rotalina oblonga, Williamson, 1858, RFGB. p. 51, pi. iv. figs. 98-100. 

 Pulvinulina oblonga, Brady, 1881, FC. p. 688, pi. cvi. fig. 4 a, b, c. 



10 Stations. 



The distribution is practically the same as that of its close ally P. auricula, from 

 which, in our opinion, it ought not to be separated. The same curious feature occurs 

 in this species at Stn. 11 as in the case of P. auricula, all the specimens being exceed- 

 ingly minute. 



297. Pulvinulina brongniartii (d'Orbigny). 



Rotalia brongniartii, d'Orbigny, 1826, TMC. p. 273. No. 27. 



Pulvinulina brongniartii, Heron-Allen & Earland, 1913, CI. p. 136, pi. xii. figs. 8, 9. 



1 Station. 



A few very compressed and rather doubtful specimens. First recorded as British by 

 us from Clare Island, ut supra. 



298. Pulvinulina lialiotidea, Heron-Allen & Earland. 



Pulvinulina lialiotidea, Heron-Allen & Earland, 1908, etc., SB. 1911, p. 338, pi. xi. figs. 6-11 ; 

 1913, CI. p. 136. 



14 Stations. 



Widely distributed and often frequent, but, as a rule, very small, the best at Stns. 3 

 and 23. 



299. Pulvinulina karsteni (lleuss). (Plate 42. figs. 34-37.) 



Rotalia karsteni, Reuss, 1855, KKM. p. 273, pi. ix. fig. 6. 

 Pulvinulina karsteni, Brady, 1884, FC. p. 698, pi. cv. figs. 8, 9. 



13 Stations. 



Generally distributed, often abundant. All the individuals are of the small pauperate 

 hyaline type widely distributed in shallow waters round the British coast. We now 

 figure this variety for the first time, for, although there are many British records, no 

 attempt to reproduce this pauperate form has been made. 



The i arliest British record of the species is in Brady's ' Fauna of the Shetiands ' —
