figure, and assignable, with some reservation, to this species, occur at Station IV. ; 

 260 fathoms. 



11. Miliolina excisa, n. sp. (Plate XL. fig. 33.) 



Characters. General form Quinqueloculine ; segments much arched and inflated, the 

 external margin of each presenting two salient ridges with well-marked crenulated 

 depressions and obtuse-angled teeth. Length about ■£$ inch (05 millim.). 



Occurs at Station II. ; 31 fathoms. 



Costa has figured a Quinqueloculine Miliolina with serrate margins from the Tertiary 

 deposit of S. Alesandro in Southern Italy, under the name Quinqueloculina denticulata 

 (Paleontologia del Regno di Napoli, p. 327, pi. xxv. fig. 6) ; and Reuss a somewhat 

 similar variety, perhaps the same, as Quinqueloculina plicatula x (Sitzungsb. d. k. Akad. 

 Wiss. Wien, 1867, vol. lv. p. 74, pi. iii. fig. 2) ; but in both of these the test is much 

 compressed, the periphery thin and carinate, and in addition to the denticulation of the 

 margin the lateral faces of the shell are more or less crenulated. 



12. Miliolina agglutinans, d'Orbigny, sp. (Plate XL. figs. 34, 35.) 

 Miliolina agglutinans, Chall. Report, p. 180, pi. 8. figs. 6, 7. 



Medium-sized specimens in four of the soundings ; 40 to 260 fathoms. 



13. Miliolina tricarinata, d'Orbigny, sp. (Plate XL. fig. 32.) 

 Miliolina tricarinata, Chall. Report, p. 165, pi. 3. fig. 17. 



A few small specimens, at 40 fathoms. 



Subfamily Hauebininji. 

 Articulina, d'Orbigny. 



14. Articulina sulcata, Reuss. (Plate XL. fig. 11.) 

 Articulina sulcata, Chall. Report, p. 183, pi. 12. figs. 12, 13. 



The drawing represents a nearly typical specimen of Articulina sulcata ; but whether 

 that be an independent species or only an arrested form of A. sagra, d'Orbigny, is 

 perhaps open to question. A single example from 940 fathoms. Reuss figures a 

 precisely similar specimen from the Lower Tertiaries of Styria. 



15. Articulina multilocularis, n. sp. (Plate XL. fig. 10.) 



Characters. Test (earlier portion 1) free, oval, compressed or complanate ; composed 

 of numerous segments arranged as in Sjnroloculina ; lateral faces of the segments flat 

 or slightly hollowed, peripheral edge square or obtuse-angular ; apertural end broad, 

 margin everted, orifice simple. Length about -^ inch (0*5 millim.).
