mainly by the chambers being less inflated, the septal lines more 

 nearly flush, the shell elongated, and has a neater and more sym- 

 metrical form than T. agyhUinans. It is in the main a coral- 

 reef form in the recent condition. Lo^yer and Upper Beds, 

 rather scarce. 



52. *7'. rugosa, Rss. This is also a characteristic coral-reef 

 sj)ecies. Lower Bed, rare. 



53. 2\ sayittida, Def. One of the commonest forms in this very 

 rich material, many of the specimens attaining a large size. Lower 

 and Upper Beds. 



54. ^T. sagittuJa var. fistuJosa, Br. A few examples of this 

 \ariety with flstulose growths on the lateral edges occur, but they 

 are relatively rare. Lower Bed. 



55 *2'. caTinata, d'Orb. This is a somewhat variable species. 

 A^Tvittgle specimen was noted, which I think must be referred to 

 it, although the septal lines are non-limbate and slightly depressed. 

 The lateral margins are sharply carinate, and give indications of 

 having possessed dentate appendages, although most of these are 

 broken, probal^ly from attrition. Lower Bed. 



5G. ^^T, gramen, d'Orb. A species of the T. sagittyJatyye, but 

 much broader in relation to its length, and with greater inflation 

 of the later segments. Lower Bed, rather scarce. 



Genus— Pavonixa, cF Orhigny. 



57. ■^7''. flaheJliformis, d'Orb. The only species of the genus 

 founded by d'Orbigny as far back as 1826, and unverifled by sub- 

 sequent researches until recent years. Mr. Brady records it from 

 nine or ten localities, one of which is Torres Straits. It is a com- 

 pressed, fan-shaped, dimorphous foraminifer ; textularian in its 

 earlier segments, the later segments being arranged in single 

 series. This is the first record of its occurrence in a fossil con- 

 dition. Lower Bed, very rare. 



Genus — Verxeuilixa, cV Orhigny. 



58. V. triqibetra, Miinst. The specimens show a considerable 

 range as to size and contour, but are always distinctly triangular 

 in shape, with rough exterior. Lower Bed, common. Upper Bed, 

 rare. 



59. * r. tricarinafa, d'Orb. More regular in shape than the 

 preceding, and less rugose. Lower Bed, rare. 



60. "^ r. jwlytitropha. Lower Bed, rare. 



61. *V. sp. A form closely allied to V. spinulosa, Beuss, f rom 

 which it difl'ers chiefly in its more elongated contour, absence of 

 spines, and nearly flush septation. Specimens were submitted to 

 Mr. Brady, who writes that he is "convinced it has been figured,'
