72 PROBOSCINA. 



DISTRIBUTION. 



Inferior Oolite : Shipton Gorge, Dorsetshire. 



Affinities. This species is most nearly allied to P. desoudini 

 (Haime), from which it may be separated by the greater elevation 

 of the peristomes and the shorter zooecia; the zoarium appears, 

 moreover, less irregular than in that species. The formula of Mr. 

 Walford's species is p, c, I, r = 3, 0-2, 1, 1-4, whereas that of 

 P. desoudini is J', 0-2, 2, 1-3. 



Its nearest Cretaceous ally is Proboscina fasciculata (Reuss). 1 

 From this, however, it is very distinct. The formula of P. fasci- 

 culata (Reuss, non Hincks) is 2, 1-2, 0, 1-2. P. echinata (Miinst.) 

 is more nearly allied to this species than to P. desoudini, Haime, 

 with which it has been contrasted in the description of the latter. 

 The species is separated from P. spatiosa, Waif., by having less 

 raised peristomes and shorter zooecia. The Pliocene and recent 

 Prob. repens is also allied, as Walford as remarked ; but it has 

 shorter, squatter zooecia, and a stronger transverse marking. 



P. spatiosa, Waif., is not represented in the Museum collection.
