 Nodosaria proxima, O. Silvestri (PI. i, figs. 9-1 1).

 fig. 15, and ('66), pi. 4, fig. 8.

Four specimens of this bilocular form of Nodosaria 

 were found, three of which I have drawn. In the one 

 not figured the initial chamber is free from costae, and is 

 distinctly larger than the second one. The test is 

 furnished with a small spine at its base, and its mouth is 

 phialine. The diameters of the two chambers in fig. 1 1 

 are equal. The test in this figure is free from costae, has 

 no spine, and the mouth appears to have been broken off. 

 Fig. 9 also appears to be fractured in the same way. 

 Fig. 10 has no costae on the initial chamber, and the 

 mouth has been damaged in the same manner. 



Mr. Millett in his Malay report (:02), p. 520, says 

 regarding the bilocular forms of N. sca/aris, Batsch, that 

 those specimens in which the costae are absent, cannot be 

 distinguished from N. simplex, Silvestri, and that this 

 latter may well be regarded as the smooth condition of 

 N. scalaris. N. scalaris has not been found in the Delos 

 material, so fig. 1 1 appears in this case to be an example 

 of the smooth form of N. proxima, Silvestri. Very rare. 



* Nodosaria chrysalis, n. sp. (PI. 1, figs. 12-14). 



Test elongate, generally curved and very transparent. 

 Primordial chamber very minute, followed by broad 

 chambers ; these rapidly increase in size until the middle 

 of the test is reached, when two or three chambers are 

 generally added, slightly decreasing in width, but gaining 

 in height. The oral end of the test is round in outline, 

 and the mouth is simple and has a short entosolenian
