rough or bark-like appearance to the test, especially on the more convex or superior 

 side. Smoother on the less convex side, especially near the aperture, which is a small 

 fissure at the point of intersection of the final and penultimate chambers. The 

 depressions between the earlier and the ultimate chambers in the immediate 

 neighbourhood of the aperture are more or less filled in with secondary shell- 

 matter. 



It occurs rarely at Stns. 11 and ] B. We have specimens of the same form from 

 'Challenger' Station 192 (ofl^ the Ki Islands, 129 fms.) and the Java Sea (45 fms.). 

 It is a somewhat anomalous form, approaching Globigerina helicina d'Orbigny (C. P. 

 & J. 1862, IF. p. 181, pi. xii. fig. 11) in the arrangement of its chambers, but 

 differing entirely in the texture of the external surface of the shell and in the aperture, 

 which is much nearer Sphceroidina dehiscens Parker & Jones (P. & J. 1865, NAAF. 

 pi. xix. fig. 5). There is, however, no trace of any internal early chambers in the 

 specimens which we have examined in balsam.

1 Station. 



At Stn. 11 two large specimens were found, comparable in all respects with 

 the figure given by Millett. This compressed and abnormal type is so entirely 

 distinct from d'Orbigny's original figure and from the general appearance of the 

 species, that we should have hesitated before attributing it to d'Orbigny's species but 

 for Millett's previous determination. The test, apart from its regular construction, 

 has, in the Kerimba specimens, an abnormally thick shell for Candeina, but the rows 

 of secondary apertures in the sutural depressions are so well displayed that its 

 generic position is clear. In view of the occurrence of similar specimens in such 

 widely separated areas, and the entire absence of typical individuals in the Kerimba 

 dredgings, it seems probable that this depressed form may be specifically distinct from 

 d'Orbigny's thin-shelled type.
