164 "TERRA NOVA" EXPEDITION.- 



forin referred to by Millett in liis tliird St. Ertli paper {u( sujmi). He then ex- 

 pressed the intention of describing and figuring it under the specific name L. 

 yokoyamae in a forthcoming paper on the Foraminifera of the shore-sands of 

 Misaki, Japan. Millett's collection of specimens and papers passed into our hands 

 on his death. We have been unable to locate any specimens, and the notes are of 

 a fragmentary natm'e, that on this variety being merely the paragraph published 

 in the St. Erth paper [id supra). But there is a drawing of the species among 

 his papers which identifies it with our N.Z. specimens, to which we give Millett's 

 specific name, reducing it to a varietal form of L. orbignyana. 



3G8. Lagena scarabaeus, sp. nov. PI. VI, figs. 20-23. 



Stations 2, 3, 5, G. 



Test oblong with romided off corners ; entosolenian. Median carina but 

 slightly developed. The two faces of the test, which are flattened and approxi- 

 mately parallel, are marked by a series of concentric ridges conforming to the 

 outline of the test. The number of these ridges varies, but in the best-marked 

 individuals there are three or more confocal rings, fairly widely separated, the 

 inner ring being divided in its long axis by a raised bar. In other specimens, 

 although the number of rings is no greater, they are set much closer together 

 so as to present a considerable central space which, instead of having the trans- 

 verse bar, is more or less roughly granular with upstanding shell-substance. 



Dimensions: — Length, • 30- -45 mm. ; breadth, ■ 22- -30 mm. ; thickness, •12 mm. 



Confined to the N.Z. area and comparatively common at the Stations. The 

 best series from Station 5. The species is very distinctive, and is remarkabh^ 

 suggestive of an Egyptian Scarab. The general appearance is very like Side 

 bottom's figure of his var. L. auriculata, var. clypeata (S. 1912, etc., LSP. 1913, 

 p. 199, pi. xviii, fig. 5) but none of the N.Z. specimens exhibits any trace of the 

 basal loops distmguishing L. auriculata. 



Nearly all the specimens are fossils. 



369. Lagena lacunata, Burrows and Holland. 



Lagena castrensis, Brady (won Schwager), Brady, 1884, FC. p. 485, jil. Ix. figs. 1, 2 and (0 3

Stations 5, 6. 



Very few typical specimens. In the majority of cases the lacuna? in the 

 shell-wall are represented by opaque inclusions of a milky-white shell-substance 

 contrasting with the hyaline surface of the test. 



370. Lagena castrensis, Schwager. 



Lagena castrensis, Schwager, 1866, FKN. p. 208, pi. v, fi<;. 22.

Stations, 2, 6, 10. 



A few specimens only from the N.Z. area, the best from Station 6.
