A large, coarse-shelled variety, scarcely so thick as Anomalina coronata, with radial 
extensions to some of the peripheral segments in the form of stout spines. It is 
isomorphous with Pulvinulina spinimargo and Rotalia calcar ; but the contour of the 
test is very variable, and a certain number of non-spinous specimens, such as that repre- 
sented in fig. 7, are almost invariably found associated with those of the normal spinous 
form. 
Anomalina polymorpha has been taken at three Stations in the North Atlantic, namely: 
— off Bermuda, 435 fathoms; off Sombrero Island, 450 fathoms; and off Culebra Island, 
390 fathoms: in the South Atlantic, off Pernambuco, 350 fathoms: in the Southern 
Ocean, off Prince Edward Island, 50 to 150 fathoms: and at three points in the South 
Pacific, — off Sydney, 410 fathoms ; west of New Zealand, 275 fathoms ; and off Kandavu, 
Fiji, 210 fathoms. 
The species is figured both by Costa and Seguenza from fossil specimens found in the 
later Miocene or Pliocene marls of Reggio in Calabria.

The genus Carpenteria was established by the late Dr. J. E. Gray 1 for certain small 
Balaniform shells found adhering to various marine objects obtained from comparatively 
shallow water in warm areas. Owing to the presence of siliceous spicules in the interior 
of the chambers, it was at first believed that the organisms in question possessed 
intermediate characters, and formed a connecting li nk between the Foraminifera and the 
Sponges. The specimens described by Dr. Gray were subsequently submitted to Dr. 
Carpenter, 2 by whom the minute structure of the test was carefully investigated, and a 
position assigned to the genus in close proximity to Glohigerina. 
Somewhat later the supposed hybrid nature of the animal was called in question by 
Prof. Max Schultze, 3 who showed that the chambers of other adherent Foraminifera often 
contained siliceous spicules, the source of which was easily traceable to sponges with 
which the specimens had been accidentally associated ; the conclusion of the author,
