Cymbalopora Poeyi, d'Orbigny. 



Heterostegina depressa, d'Orbigny. 

 These form altogether a considerable list, considering 

 that the entire weight of sea-weed_, shells, and extraneous 

 adherent matter could not be more than fifteen or twenty 

 grains. One or two forms were represented by a single 

 specimen only, but no species had been retained of which a 

 good characteristic example, large or small, were not 

 present; doubtful forms were rejected, or the list might 

 have been considerably extended. The most abundant 

 species of Calcarina was the pretty hispid modification 

 figured by Dr. Carpenter (Introd. Foram., PI. xiv, fig. 6), 

 but not hitherto described or named as far as I know. I 

 propose to call this C. hispida, and its characters will stand 

 ■as follow. I have met with larger specimens in Australa- 

 sian sands, but have never seen any so beautifully perfect. 



Calcarina hispida, spec. nov. — Test free, unequally 

 biconvex, rotalian ; margin, thin, lobulate or rowelled ; seg- 

 ments numerous, slightly inflated ; peripheral borders thin, 

 rounded, angular, or produced sufficiently to form radiating 

 spurs. Surface covered with adpressed spiny processes, 

 obscuring the sutures, except those of the later chambers. 

 Diamet. -.'^ inch (1'3 mm.) or more [vide Carpenter, op. cit., 

 PI. xiv, fig. 6). The characters are, indeed, very much 

 those of Calcarina calcar, excepting for the superficial spiny 

 armature. 



Quinqueloculina ornatissima (Karrer, Sitzungsb. k. Akad. 

 Wiss. Wien, 1868, vol. Iviii, p. 151, pi. 3, fig. 2) deserves a 

 passing notice. It is an interesting, highly ornate form 

 with transverse crenulations crossed by longitudinal strise, 

 and though I had previously found it in some Polynesian 

 sands, it has not been recorded as a recent species. Dr. 

 Karrer's specimens were from the Miocene of the Banat, in 

 Austria. Only a single example was found in this Loo Choo 

 gathering, and that is slightly broken. 



At the time I received the sea-weed from Dr. Wright I 

 was endeavouring to summarise what was known of the
