3 Stations. 



A single specimen at each Stn., all, as usual, imperfect. Both the oral and the 

 bulbous aboral portions, however, are represented. 



Haplophragmitjm, Reuss. 



78. Haplopliragmium pseudospirale (Williamson). (Plate 40. fig. 14.) 

 Proteonina pseudospiralis, Williamson, 1858, RPGB. p. 2, pi. i. figs. 2, 3.

15 Stations. 



Generally distributed and fairly abundant at many of the Stns. There is considerable 

 variety of form. At the majority of Stns. the specimens are all of the involute form 

 represented by Goes's figs. (G. 1894, ASF. pi. v. figs. 142-3). This is practically 

 isomorphous with Haplophragmium canarieiise, differing only in the rough texture of 

 the wall and the absence or obscurity of the septation. The umbilical part is usually 

 strongly depressed. This may possibly represent the early stages of the test, but the 

 entire absence of the elongate crozier-form at many Stns. where the circular form occurs 

 is noticeable. The crozier-form occurs large and well developed at Stns. 2, 4, 9, 14, 18, 

 and 26. At Stns. 4 and 26 another form occurs in which the circular portion is 

 followed by a single sharply-pointed chamber; we figure this variety, whicli we have 

 already met with in anchor-mud from Paranagua, Brazil. It appears to be isomorphous 

 with Cristellaria variabilis, Beuss. 



79. Haplophragmium canariense (d'Orbigny). (Plate 40. figs. 12, 13.) 



Noniunina canadensis, d'Orbigny, 1839, F1C. p. 128, pi. ii. figs. 33, 34. 

 Haplophragmium canariense, Brady, 1884, FC. p. 310, pi. xxxv. figs. 1-5. 



22 Stations. 



Almost universally distributed, often very common. The specimens are almost 

 without exception of a thin evolute type. At some Stns., however, they were very 

 small and starved. At Stns. 10 and 16 these small specimens are almost entirely built 

 up of small mica-plates as in Reophax scotlii, Chaster. At Stns. 10, 18, and 20, where 

 the species was abundant, abnormal specimens, one of wiiich we figure, in which the 

 initial spiral growth is succeeded by a series of irregularly Lituoline chambers, occurred ; 

 these may be compared in appearance and construction with Truncatulma variabilis, 

 d'Orb. (Having found this again off the coast of Cornwall, we are naming it in our 

 forthcoming paper.) The general colour throughout the dredgings is normally ferru- 

 ginous, but occasional grey individuals occur at most Stns., and at Stns. 5 and 17 

 they largely predominate.
