Affinities. 
This small species was described by Vine from specimens obtained 
from P. M. Duncan. It differs from D. vmei by the larger number 
and greater regularity of the vertical series of apertures round the 
margin of the disc, the shortness of the stem, and the fungiform 
shape of the zoarium. The upper surface was figured by Vine 
in 1884 and resembles a Berenicea, from which it differs by the 
fasciculate structure of the zoarium. 
Vine remarked (1889, op. cit. p. 270), “there is no species in the 
whole of the Cambridge collection that I have had more bother with 
than the above.” The trouble was no doubt largely due to the 
scarcity and imperfection of the material. I know it only by 
six small specimens, and in the first volume of tlie Catalogue 
(p. 281) I referred to the species as a larval fasciculate form. That 
conclusion I still accept, and Biscofascigera appears to be the 
safest genus in which to include it. A doubt, however, as to 
this conclusion is suggested bj" the specimen (D. 1864) figured 
on PL VII. Fig. 3. The specimen from above (Fig. 3^^) appears 
to agree in all essentials with D. 1857, figured on PL IV. Figs. 5a, b ; 
and the section across the lower side of D. 1857 agrees in structure 
with a simple Biscofascigera. But the view of D. 1864 from the 
side (PL VII. Fig. 3b) shows that the apertures tend to become 
serial as in a Bomopora, or in Trochiliopora humei', and it is 
therefore possible that this species, B. paucipora, marks the 
departure of Trochiliopora and its allies with serial apertures 
from the simpler plan of Biscofascigera. The serial arrangement 
in D. 1864 is, however, not clearly shown all around the zoarium, 
as the specimen is not well preserved. 
Vine identified two specimens (D. 1864 and D. 1865) of this 
species as belonging to the recent Mediterranean Melobesia radiata 
of Audouin.
