144. Bolivina textilarioides, Reuss. 



Bolivina textilan'uicies, Reuss, 1862, NHG, p. 81, pi. x, fig. i. 



Bolivina textilarioides, Brady, 1884, FC, p. 419, pi. Hi, fig. 23 (only). 



Bolivina textilarioides, Heron-Allen and Earland, 1916, FWS, p. 238, pi. xli, figs. 10-14. 



Eleven stations: 53, 235, 236; WS 79, 83, 87, 89, 90, 93, 97, 433. 



Never very common and never quite typical. At most of the stations the species is 

 represented by a rough and thick-walled variety very similar to that figured by us 

 {tit supra). At 235 and WS 87, 90, this roughness is confined to the upper margin of the 

 chambers, approaching the form separated by Cushman under the specific name spinescens. 



145. Bolivina spinescens, Cushman (Plate IX, figs. 7, 8). 



Bolivina textilarioides, Brady, 1884, FC, p. 419, pi. Hi, figs. 24, 25. 

 Bolivina spinescens, Millett, 1898, etc., FM, 1900, p. 542, pi. iv, fig. 5. 

 Bolivina spinescens, Cushman, 1910, etc., FNP, 1911, p. 46, fig. 76. 



Three stations: 235, 236; WS 433. 



At these stations, the variation referred to under the last species reaches its maximum 

 development, and specimens unquestionably referable to Cushman 's species are found, 

 common at WS 433. 



146. Bolivina robusta, Brady. 



Bolivina robusta, Brady, 1879, etc., RRC, 1881, p. 57; 1884, FC, p. 421, pi. liii, figs. 7-9. 

 Bolivina robusta, Cushman, 1918, etc., FAO, 1922, p. 46, pi. vi, fig. 6. 



Eight stations: WS 79, 83, 88, 97, 109, 210, 217, 245. 



Rare, and as a rule rather pauperate. Good specimens at WS 97, and others, less 

 typical, at WS 210, 217, 245. 



147. Bolivina compacta, Sidebottom. 



Bolivina compacta, Sidebottom, 1904, etc., RED, 1905, p. 15, pi. iii, fig. 7. 

 Bolivina compacta, Cushman, 1910, etc., FNP, 191 1, p. 36, fig. 58. 



Two stations : 388 ; WS 88. 



Several good specimens at each station. 



148. Bolivina dilatata, Reuss. 



Bolivina dilatata, Reuss, 1849-50, EOT, p. 381, pi. iii (xlviii), fig, 15. 

 Bolivina dilatata, Cushman, 1910, etc., FNP, 191 1, p. 33, fig. 54. 



Seven stations: WS 79, 80, 88, 90, 92, 99, 408. 



At many stations the specimens are rather poor, but excellent and typical individuals 

 occur at WS 88, smaller and less typical at WS 90 and 92. 



149. Bolivina difformis (Williamson). 



Texttilaria variabilis var. dijformis, Williamson, 1858, RFGB, p. 77, pi. vi, figs. 166, 167. 

 Bolivina difformis, Brady, 1887, SBRF, p. 899. 



Five stations: 48; WS 90, 92, 99, 408.
