550 MESSES. E. HEROiy-ALLEN AND A. EAELAND ON THE 



records of its occurrence off Barbados (100 fms.), off Cape Bj'ron, N. S. V/ales 

 (111 fms., costate), and off the coast of New Zealand, North Island (various depths). 



The specimens range between 0*5 and 1-5 mm. in length. Greatest diameter of 

 chamber 0-6 mm.

This typical tropical form occurs at nearly all the Stns. and often in great 

 profusion, but is absent at Stn. 13, and extremely rare at Stns. 5, 7, and 10. The 

 specimens call for little remark ; they are quite typical and constant in their 

 irregularity of form and in the characteristic multi-tubular aperture. They attain 

 abnormally large dimensions at Stns. 3 and 9. 



Under this species it would seem convenient to record those abnormal nubecularine 

 miliolids, some of which we figure (Plate XL. figs. 8-10), which, while no doubt phylo- 

 genetically akin to Miliolina lahiosa (d'Orbigny, 1839, FC. p. 178, pi. x. figs. 12-14), 

 present no definite plan of growth. They occur in considerable numbers at Stns. 12 

 and IX. They are easily separable from the typical N. hradyi by the character of the 

 aperture, which is in nearly all cases a comparatively large and irregular terminal 

 orifice.
