230 FORAMINIFERA OF THE CRAG. 



of longitudinal costulse is variable in expi'ession and extent, frequently not 

 affecting tte youngest chambers, and- sometimes limited to the earliest, and 

 partially affecting the tops of the other chambers near to or just below the 

 junction with the next segment. This kind of ornament is present in several 

 Dentalinse, such as B. Sandhergeri, D. Girardana, and D. intermittens, Reuss, ' Sitz. 

 k. Akad. Wiss. Wien,' vol. xviii, 1856, p. 224, pi, i, figs. 5, 6, 7 ; and D. proteus, 

 Reuss, ibid., vol. xliv, 1861, p. 306, pi. i, figs. 6 — 9. 



Note. — Vaginulina striata, d'Orb., after Soldani, is much compressed, 

 symmetrically tapering, longitudinally costulate, compact, and rigid in its style of 

 growth ; and was taken as the type of V. legmnen, var. (Part I, p. 66). As this 

 form has been included by some in Vag. linearis, its synonymy is here appended.

Occurrence. — Vaginulina linearis is a shallow-water form, rather commonly met 

 with off the British coasts, and apparently most at home in the waters of the 

 North Temperate Zone. Specimens were obtained by the ' Challenger ' from 

 three stations : — Off Bermuda (435 fathoms), off Culebra Island (390 fathoms), 

 and south-east of Pernambuco (350 fathoms). In a fossil condition it has been 

 found in the London Clay (Eocene) ; Tertiary of Upper Silesia ; the Miocene of 

 Italy, and Muddy Creek (Victoria) ; and in the Pliocene of Italy. 



So far as the Crag is concerned, we have nothing to add to the record from 

 Sutton in the First Part of the Monogi-aph.
