forms of Biloculina, named respectively in Professor William- 
son’s Work, — B. ringens, typica and B. ringens, var. carinata, 
will suggest, I think, a doubt as to whether it is correct to 
throw them together as one species, the texture of the shells as 
well as the form of their mouths being very different. 
All the named varieties of Miliolina occur in abundance, 
and among them are great numbers of evidently distorted 
and misshapen specimens which appear to me to give no 
help whatever in the way of supplying inosculating forms, 
but may prove useful by indicating facts bearing on the 
general development of the animals. Specimens with the 
last chamber, not broken but clearly left incomplete, are by 
no means uncommon. 
Lepralice . — The specimens of many species of Lepraliae 
which I have to show are from dead shells picked up from 
the shore of Dogs Bay, and from others dredged at the mouth 
of Birterbuy Bay. These promise a very rich harvest, and 
indications of a great number of species are further given by 
the specimens of detached cells and fragments picked out 
from the shell-sand, though the latter are generally too 
broken to serve for exact examination or description. At 
present I have done very little with the specimens, but can- 
not altogether omit mentioning them. Lepralia figularis is 
common, and the specimens are very beautiful ones. There 
are also many examples of a species nearly agreeing, but not 
quite identical, with Johnston’s Lepralia ovalis; and Lepralia 
ciliata var. /3 of Johnston, Mr. Hassall’s Lepralia insignis, is 
plentiful. There are many other striking forms which I 
have not yet had the means to identify, besides common ones 
about which there is no doubt ; but at present 1 must pass 
over the subject without attempting to give a list. 
EchinoUerrnata . — The present list includes ten species, 
and on the table are very handsome specimens of four of 
these, namely, TTraster glacialis and U. violacea, Luidia 
fragillissima and Echinus lividus. The acquisition of the two
