This form is represented by a fine but solitary example from 

 Station 13, in Area 1. 



Pelosina distoma sp. n., Plate XI. figs. 5, 6. 



Test pyriform or fusiform, with a rounded aperture at each 

 extremity, that at the superior end being the larger. From the 

 inferior orifice the chitinous lining protrudes in the form of a short 

 tube. Length 0*35 mm. 



In his definition of the genus Pelosina Brady specifies " aper- 

 ture single." This limitation would exclude the species uuder con- 

 sideration, but it is so evidently a true Pelosina that the emendation 

 of Brady's definition would be less objectionable than the creation 

 of a new genus. 



The test of P. distoma is unusually dense, and often has a 

 polished surface, which gives it a superficial resemblance to 

 Glandulina. Sometimes there is a constriction in the test, as 

 shown by fig. 6. The chitinous membrane is in some specimens 

 visible at the superior orifice, but never forms there a projecting 

 tube as in P. rotundata. 



In its distribution it appears to be very local, being somewhat 

 abundant at Station 6, and is represented sparingly at Station 22, 

 but these are the only localities where it has been found. 



Thurammina favosa Flint, Plate XL fig. 7. 



Thurammina favosa Flint, 1899, Rep. U.S. Nat. Mus. for 1897 

 (1899) p. 278, pi. xxi. fig. 2. Thyrammina favosa (Flint) Bhumbler, 

 1903, Schaudinn's Archiv fur Protistenkunde, vol. iii. p. 236, 

 fig. 65. 



This is a doubtful Foraminifer, and I had hesitated in accepting 

 it, but since it has been admitted by Flint and Rhumbler, I feel 

 compelled to include it in the present Report. Like the also 

 doubtful Reophax pleurostomelloides before described, there is a 

 certain amount of flexibility about the test reminiscent of the 

 vegetable kingdom, to which possibly both may belong. 



In the Malay Archipelago it occurs at several Stations, but is 

 most abundant in Area 1. 



The ' Gazelle ' Stations are in the Gulf of Mexico ; 26 and 

 420 fathoms. 



In conclusion, it should be explained that a few doubtful forms 

 ■ which may or may not be Foraminifera, have purposely been
