1. Isuhecularia hiciftiqa Defiance, pi. Y. files. 1, 2. (Rets., B. 1884, F.C. 



p. 134; H-A. cl- E. 1915, F.K.A. p. 549.) At Station I, extremely 

 well-grown speciujens, including a remarkable ]ndivid^^al which we 

 figure, in which the final chamber is separated into two distinct 

 tubular outgrowths, bearing the apertures, suggesting Koboz' 

 figures of Cakituha poJyinorpha* Distribution : Station I, r. ; 

 Station.'^ II, V, v.r. (M.) 



2. BiJocuIina dejjr<'ssa d'Orbigny. (Eefs., B, 1884, F.C. p. 145.) I, v.c. ; 



II, III, IV, V, IX, v.r. (M.) (P.) 



3. i?. rm^e«.s (Lamarck). (Refs., H-A. cV E. 1915, F.K.A. p. 550.) (P.*) 



4. B. elongata d'Orbigny, pi. V. figs. 3-5. (Refs., B. 1884, F.C. p. 144.) We 



figure a large specimen from Station I as //. elongata owing to its 

 general contour. It might, however, on account of its large aper- 

 ture, have been equally well recorded as B. ringens d'Orb. Worth 

 records B. rinqens var. pataiionica Williamson, which is a synonym 

 of B. tlongata d'Orb. (M.) (P.) (R.) 



5. B. irregularis d'Orbigny. (Refs., B. 1884, F.C. p. 140.) I, v.r. 



6. B. txbtdom Cjosiii. (Refs., B. 1884, F.C. p. 147.) (P.*) Worth 



records this with some reservation, but it is a well-marked form and 

 not uncommon in moderately deep water oft" the S.-W. of Ireland. 



7. Spiroloculina grati Terquem. (Refs., B. 1884, F.C. p. 155 ; H-A. & E. 



1915, F.K.A. p. 552.) Single specimens at I, IV, V, VIII. 



8. S. excavata d'Orbigny. (Refs., B. 1884, F.C. p. 151 ; H-A. and E. 1915, 



F.K.A. p. 554.) I, II, III, v.r. ; IV, VII, VIII, v.r. ; V, f. ; X. (P.) 



9. S. dormta Reuss. (Refs., H-A. & E. 1915, F.K.A. p. 554.) The speci- 



mens are very weak and hardly distinguishable from S.planulata. 

 (M., P. and R. as »S'. Uinhuta.) I, v.r. 



10. S. planulata (Lamarck). (Refs., B. 1884, F.C. p. 148.) I, II, III, VII,
