 specimens are all strongly limbate.

Universally distributed, but most abundantly and best developed in the 

 extreme south. The specimens from the Stations south of Station 38 are all 

 large, usually of the high-domed irregular type. Abundant both in the free and 

 sessile conditions. At Station 46 a specimen was found living sessile on a small 

 Pycnogonid. Most of the Antarctic specimens are thin-wallcd, with a tendency 

 to depauperation and chitinous growth. The most noticeable record is that of 

 a single small, thin-walled but quite typical, individual at Station 13 in a depth 

 of 3,003 fms. ; with the exception of a few starved Miliolids, it represents the 

 onlv benthic calcareous organisms found in that gathering, and the depth is 

 enormously beyond any previous record for the species. In the N.Z. area the 

 specimens are less abundant and generally poorly developed, except at Stations 

 5 and 6, Fossil specimens at several N.Z. Stations and, as with many other 

 species, the fossils are noticeably larger and more strongly developed than the 

 recent individuals.

A few typical specimens. This is a- species liable to be overlooked on account 



of its minute size.
