Scantily distributed, and, as a rule, only a few specimens at each Stn., the best being 

 at Stns. 1, 6, and 12. All the individuals are small in size, but quite typical ; in 

 many of them the sutures are limbate all over the shell.

At Stn. 11a single fully developed individual, which we figure and which we have 

 little hesitation in ascribing to this species, although the shallowness of the deposit 

 renders its occurrence very noteworthy, P. fartschiana being normally a deep-water 

 type. It is characterized by a translucent hyaline brown shell with thick and opaque 

 marginal edges. At the same Stn. a number of specimens occur which apparently 

 represent the megalospheric type, perhaps in an arrested stage of development. In 

 these latter individuals the later chambers tend to grow over the inferior or convex 

 face of the shell in broad overlapping flaps, so that not more than two or at the most 

 three chambers are visible. The shell-wall is much thicker in the megalospheric 

 than in the microspheric specimens. The colour is, as a rule, the same ochreous-brown 

 tint, but one or two white specimens, perhaps representing dead shells, also occur.
