There are numerous finely developed specimens of this species 

 which Sidebottom records as "two very small immature specimens." 



POLYSTOMELLA MILLETTD Heron-Allen and Earland. 



Polystomella verriculata Millett, Joiu'n. Roy. Micr. Soc, 1904, p. 604, pi. 11, 



fig. 3. 

 Polystomella millettii Heron-Allen and Earland, Trans. Zool. Soc, p. 735, pi. 



53, figs. 38-42. 



There are five specimens which may be possibly referred to this 

 species. They have a reticulate surface, the lines of which are 

 oblique to the sutures. In the specimens from New Zealand, even 

 in the last-formed chambers, there is not developed the angled con- 

 dition shown by Heron-Allen and Earland in their type figures. 

 These correspond fairly well with the figures of P. hedleyi figured 

 by Jensen.^ His specimens, however, have less of the angled pattern 

 than is developed in our specimens, and ours are not very closely 

 like those of Millett. From the various figures given of similar 

 specimens of the Philippines and from this general region, there is 

 either one very variable species or numerous varieties or species 

 developed, and it should be carefully collected and studied in the 

 regions to determine this. 



Family MILIOLIDAE. 



Subfamily Cornuspirininae. 



Genus CORNUSPIRA Schultze, 1854. 



CORNUSPIRA FOLIACEA Costa, var. EXP ANSA Chapman. 



Cornuspiru carinata Costa, var. expansa Chapman, Biol. Res. Endeavour, vol. 3, 

 1915, p. 318, pi. 1, fig. 3. 



There are several well-developed specimens which are very clearly 

 this variety described by Chapman. Our specimens, however, are 

 better developed than that figured by Chapman. It is very clear, 

 both from these specimens and from abundant Philippine material, 

 that this would be a variety of C. foliacea. Some of the specimens 

 are very expanded and are nearly 4 mm. in length and nearly as 

 much in breadth. There are slight traces of very fine longitudinal 

 striae.
