Abstract
A PAPER by A. Goës “On a peculiar type of Arenaceous Foraminifer from the American tropical Pacific, Neusina Agassizi,” has just been published in the “Bulletin of the Museum of Comp. Zoology, at Harvard College,” vol. xxiii. No.5, in which the author describes some remarkable forms dredged by the Albatross expedition in the Pacific of Central America. They are supposed to be foraminifera, are of leaf-like shape, measure up to 190 mm. in breadth, and are marked by concentric lines of growth. Their interior shows a stroma, consisting of fine chitinous threads, enclosing sand and débris of shells. Without wishing to recapitulate all the various points of structure, I will only say that there can be no doubt that these forms belong to Hæckel's deep sea keratosa (see Challenger report, vol. xxxii.) from the tropical Pacific, and I should think that Neusina Agassizi is identical with Stannophyllum zonarium, Hæckel. I happen to have here a Challenger specimen of this latter species, kindly lent to me by the Manchester Museum, and its microscopic examination convinces me of the identity of the two forms.
