DRILLIA BROCCHII. 219 



Var. proxima, nov. Plate XXVIII, figs. 3 — 4. 



Specific Characters. — Differs from the type in size, form and sculptnre ; whorls 

 8 — 9, nearly flat, regularly diminishing upwards, the last about half the total length, 

 excavated below ; ornamented by rather coarse but not very prominent spiral 

 lines, some of them forming obscure cancellate bands on the upper whorls ; suture 

 slight; spire elongate, acutely conical ; mouth short, narrow, passing without break 

 into a very short canal ; outer lip gently curved, not expanded, continuous with 

 the outline of the spire ; columella flexuous. 



Dimensions. — L. 12 — 17 mm. B. 5 — 6 mm. 



Distribution. — Not known living. 



Fossil : Coralline Crag : Gedgrave, Boyton. Waltonian : Little 

 Oakley. Newbournian : Waldringfield. 



BemarJiS. — The specimens (PI. XXVIII, figs. 3, 4) figured under the present 

 name are from the British Museum, where a difficulty similar to my own has 

 been felt as to their correct identification, the one from Waldringfield (fig. 4) 

 being labelled Pleurotoma decorata, A. Bell, the other from Boyton (fig. 3) DrilUa 

 Lopresfiana, Calcara. The two seem to be, however, if not actually the same, 

 very nearly allied. As to the first of these I have on PI. XXVII, fig. 3 

 figured Mr. Bell's undescribed type specimen of Pleurotoma decorata in the York 

 Museum as Oligotoma decorata. It is not the same as the one in question from the 

 British Museum. As to the second, P. Loprestianum was named but not figured 

 by Calcara, but there seems some doubt as to what it really was. Prof. Kobelt 

 has represented two different forms under the latter name (in his text, not on his 

 plate),' one of which he identifies with P. crispatum of Reeve, ^ the other with P. 

 crispaftivi of Philippi,^ but with neither of them do our fossils correspond. In 

 sculpture they approach the typical 0. hipunctida, but differ from it in form, 

 especially in the flatness of the whorls and their elongated spire. PI. XXVIII, 

 figs. 5 — 8, seem to represent a variety intermediate between the present shell and 

 0. hipunctida.
