256 MESSES. E. HERON-ALLEN AND A. EAELAND ON THE 



208. Nodosaria calomorpha, Reuss. 



Nodosaria calomorpha, Reuss, 1865-6, FABS. p. 129, pi. i. figs. 15-19. 

 Brady, 1884, FC. p. 497, pi. lxi. figs. 23-27. 



1 Station. 



Two quite typical small specimens. 



209. Nodosaria pyrula, d'Orbigny. 



Nodosaria pyrula; d'Orbiguy, 1826, TMC. p. 253. No. 13. 



Brady, 1884, FC. p. 497, pi. lxii. figs. 10-12. 



17 Stations. 



Widely distributed and abundant at some Stns., the best at Stns. 2, 4, 10, 14, and 18. 

 Typical N. pyrula occurs nearly everywhere, but the longer-chambered form with 

 short stolon-tubes [=iV. (Dentalina) guttifera, d'Orbigny, 1846, EEV. p. 49, pi. ii. 

 figs. 11-13, not 14] is the only representative at Stns. 11 and 17. Both forms occur 

 together at several other Stns. 



210. Nodosaria filiformis, d'Orbigny. 



Nodosaria filiformis, d'Orbigny, 1826, TMC. p. 253. No. 14. 



Brady, 1884, FC. p. 500, pi. lxiii. figs. 3-5. 



8 Stations. 



Scantily distributed, often represented only by fragments, the best at Stn. 4. Many 

 of the specimens are distorted, a very common feature in this species. 



211. Nodosaria consobrina, d'Orbigny. 



Nodosaria {D.) consobrina, d'Orbiguy, 1846, FFV. p. 46. pi. ii. figs. 1-3. 



Brady, 1884, FC. p. 501, pi. lxii. figs. 23, 24. 



3 Stations. 



Very sparingly represented, good and typical at Stn. 18. 



212. Nodosaria communis, d'Orbigny. (Plate 42. figs. 1, 2.) 



Nodosaria (B.) communis, d'Orbigny, 1826, TMC. p. 254. No. 35. 



„ Brady, 1884, FC. p.. 504, pi. lxii. figs. 19-22. 



17 Stations. 



Generally distributed, but never very common, the specimens usually small, thin- 

 shelled, and weak, but large and fairly typical specimens at Stns. 3 and 20. Two 

 distinct forms occur, sometimes together, but often isolated — the normal round-in-section 

 N. communis and a compressed or vaginuline form. The latter often develops in its 

 later chambers into the normal round type. The best examples of the vaginuline type 

 were at Stns. 4, 18, 20, and 21. Monstrous or double or distorted specimens, showing 

 double or distorted primordial chambers, occur at several Stns., notably at Stn. 18, and 

 are referable to both forms. The vaginuline or compressed form is very common in
