202 FORAMINIFERA OF THE CRAG. 



Fossil specimens have been recorded from the Miocene of Messina (Seguenza), 

 and from the Pleistocene of Canada and the North-east of Ii'eland. The Crag 

 specimens were obtained from Sutton.

pi. iv, figs. 19 a and d (Young ?). 

 — — Brady, 1884. Eeport 'Challenger,' pp. 447 and 480, 



pi. Ix, figs. 10, 18—20; 8? and 17 ? 



Characters. — Body long, flask-shaped, compressed, with tubulated wing, fre- 

 quently emarginate at the base, and with a raised border immediately surrounding 

 the body on both sides of the shell. Our example from the Crag is destitute of 

 the fine broad flange or wing present in more typical specimens. 



Occurrence. — Jjagena formosa was found by the ' Challenger ' at several stations, 

 but for the most part in very deep water, 1075 to 2750 fathoms. Small or broken 

 specimens were found in the Southern Ocean at depths of 50 — 150 fathoms. As a 

 fossil it has previously been recorded only from the Pliocene of Kar-Nicobar. 

 We have, however, large specimens from the Casterlian and Scaldisian of Antwerp. 

 In the Coralline Crag we have found it (but rarely) in every zone examined except 

 at Aldborough (zone g).

Lagena Formosa, var. comata, Brady, 1SS4. Eeport ' Challenger,' pp. 447 and 



480, pi. Ix, fig. 22. 



Characters. — Form similar to that of L. formosa, but the body of the shell is 

 marked with longitudinal stride and thin rugulse in Brady's fig. 22. Although our 

 specimen from the Crag is marked with fewer and coarser costulce, and has no broad 

 marginal flange, yet it evidently comes into the same category of sub-varieties of 

 the lagenoides sub-type as the foregoing forms. 



Occurrence. — Lagena formosa, var. comata, Brady. This sub-variety, charac- 

 terised by the striate surface of the body-chamber, was first recorded in the 

 'Challenger' Report from the North Pacific (1850 fathoms). We have found a 

 well-developed specimen in the Scaldisian of Antwerp. The example figured in 

 Plate VII, fig. 7, is from Sutton, zone f.
