Milioline in its oral features. This variation establishes another 

 point of resemblance between Hauerina and JfUioIina, in addi- 

 tion to that whicli is exhibited by the Milioline arrangement of 

 its earlier segments. Upper Bed, moderately common. 



Genus — Vertebralixa, iVOrhiyny. 



34. V. insiynis, Brady. A feeble variety of this rare form 

 occurs in the material, the triangular and carinate periphery, the 

 ornamentation in regular parallel lines, and the absence of recti- 

 lineal growth are sufficient to mark the species. This is the lirst 

 record of it in a fossil state, and it is only known as an existing 

 species from three localities, one of which is Torres Straits. 

 Lower and Upper Beds, rare. 



Genus — Articulixa, cVOrhiyny. 



35. "^A. sulcata, Rss. Reuss figures a minute and somewhat 

 dubious form under this name from the Tertiaries of Germany. 

 It is known as a recent shell from four " Challenger " stations, 

 one being off Raine Island, Torres Straits. Lower Bed, rare. 



36. *A. sayra, d'Orb. A complete examj^le and the final seg- 

 ment of another were the only indications of this species observed. 

 Lower Bed. 



Genus — ^Orbitolites, Lamarck. 



37. "^O. complanata, Lamk. Several fragments of fairly large 

 shells were noted, but in each case these were broken and worn 

 by attrition. They are most likely to be derived fossils not 

 proper to the bed. Lower Bed. 



Genus — Planispirina, Hequenza. 



38. P. siymoidea, Brady. This is one of the "Challenger" 

 species, but only noted at five stations. Lower Bed, moderately 

 common. Upper Bed, rare. 



39. '^P. exiyua, Brady. Two specimens occurred of this minute 

 but interesting little shell. Like the preceding, this is the first 

 record of its occurrence in the fossil condition. Lower Bed, rare, 



FAMILY LITUOLID.E. 

 Genus — Lituola, Lamarck. 



40. fZ. nautiloidea, Lamk. A single example, shoAving laby- 

 rinthic structure, from Upper Bed. 



Genus — Placopsilixa, fVOrhiyny. 

 4L ^P. Cenomana, d'Orb. Single specimen from Upper Bed.
