101. BoLiviNA LIMBATA Brady. 
Bolivina limhata Brady, 1884, FC. p, 419, pi. 52. figs. 26-28 
Heroii-Alleu & Earland, 1913, CI. p. 67, pi. 5. figs. 2, 3 ; 
1914-15, FKA. p. 646, pi. 50. figs. 1-4. 
Rare, but large and well-developed. Most of the specimens are bifarine 
in their later development. 
102. Bolivina limbata, var. abbeeviata, nov. (PL 36. figs. 25-27.) 
Test compressed, consisting of 4 to 7 pairs of chambers with rounded 
marginal edges, heavily limbate but with flush sutures. Al)oral extremity 
rounded. The shell reaches its maximum breadth at about the third pair of 
chambers^ and therefore the sides are almost parallel. Aperture large, 
extending over the septal face of the final chamber. Surface of the chambers 
prominently perforate between the clear sutural lines. 
This is a very easily recognized little form, and not uncommon in shallow- 
water tropical gatherings. It may represent an intermediate type between 
B. tetetilarioides (which it resembles in the straight sutural lines, almost 
vertical to the long axis) and the typical B. limbata. It never, so far as we 
have observed, has that tendency to develop a bifarine terminal portion so 
characteristic of the latter species. 
103. Bolivina variabilis ( Williamson). 
Texttdaria variahilis (typica) Williamson, 1858, EFGB. p. 76, pi. 6. figs. 162, 
163. 
Bolivina „ Heron-Alleu & Earland, 1914-15, FKA. p. 647. 
The most typical Bolivina of the gathering, frequent, well-developed, and 
exhibiting a considerable range in the extent of the surface-markings. 
104. Bolivina plicata d'OrUgny. 
Bolivina plicata d'Orbigny, 1839, FAM. p. 62, pi. 8. figs. 4-7. 
Goes, 1894, ASF. p. 51, pi. 9. figs. 487, 488. 
Two specimens, very stronglj^ marked. 
105. Bolivina inflata Heron-Allen tx Earland. 
Bolivina inflata Heron-Allen & Earland, 1913, CI. p. 68, pi. 4. figs. 16-19 ; 
1916, F.W.S. p. 240. 
Not uncommon and quite typical.
