Gaudryina hirta sp. n., plate I. fig. 10. 



Test hyaline, elongate, tapering towards the aboral end, com- 

 pressed ; triserial portion small and obscure. Biserial chambers 

 numerous and inflated. Aperture erect, oval, with a depressed margin. 

 Surface of test covered with short spines. Length 0'29 mm. 



In this species the biserial portion appears to be more Bulimine 

 than Textularian, as well in the texture of the test as in the position 

 of the aperture. In the Gaudryinm there is admittedly considerable 

 variation in these features, and it is not necessary to establish a new 

 genus for the reception of this form. The specimens are remarkably 

 uniform in size and structure, and in the number of chambers. 



It is very abundant in the Malay Archipelago, and is found at 

 most of the Stations. 



This is one of the forms which illustrate the peculiarity of the 

 Malay Region in containing numerous species, widely distributed and 

 in vast profusion, which have not been recorded from any other 

 locality.

Is represented by a few feeble specimens from Station 13. 

 Brady names seven localities at which it has been found in the 

 living condition. It seems to be at its best in Torres Strait. 



Gaudryina Wrightiana sp. n., plate I. figs. 11, 12. 



Gaudryina rugosa (d'Orb.) Beissel, 1891, Abhandl. k. Preuss. 

 Geol. Landesanstalt, Heft 3, p. 69, pi. xiii. figs. 30-33. 



Test wedge-shaped; triserial portion with flat faces and acute or 

 carinate edges ; biserial portion quadrilateral, one of the lateral faces 

 convex, the other concave. Peripheral margins broad and flat, and 

 inclined towards the concave lateral face. Length 0*30 mm. 



This is an interesting form of the G. rugosa group, and is closely 

 allied to G. Jonesiana* Wright, from which it differs in its length, 

 and in having one of the lateral faces convex. The sutures of the 

 biserial portion are sometimes limbate. 



It is not uncommon at Station 13, and occurs also at Station 2. 



The specimen figured by Beissel is from the chalk-marl of Aix-la- 

 Ohapelle.
