SUPPLEMENT. 



During the period that the Monograph on the Inferior Oolite Gasteropoda has 

 been in course of publication, a certain number of specimens have been noticed or 

 procured too late to be recorded in their proper places. They are mostly rare 

 forms, and in some cases the genus is doubtful. These it is now proposed 

 somewhat briefly to describe, in most cases with a figure. See Plates XLIII and 

 XLIV. 



436. PuEPOEOiDEA, species. Plate XLIV, fig. 9. 



A single fragment of a large Pu7ynroidea was recently obtained from the 

 Lincolnshire Limestone at Rauceby. There is not enough material to constitute 

 a species, but the circumstance is interesting from its being the only instance of 

 Purpuroidea as yet recorded from the Inferior Oolite of this country. 



Though apparently differing from any of the Great Oolite species, it most 

 nearly resembles P. Morrisea, Buvignier, which is the common form at 

 Minchinhampton. Possibly also some of the Corallian species described by 

 Buvignier, such as P. Moreana, may be near. 



437. PuRPTJRiNA VARicosA, Lijcett, 1850. Not figured. 



1850. TuEBO TAEicosus, Lycett. Ann. Mag. Nat. Hist., 2nd ser., vol. vi, p. 416. 

 1853. _ _ _ Proc. Cotteswold Field Club, vol. i, p. 77. 



The following is Lycett's description : — " Turrited, whorls six, convex, each 

 with four encircling, rounded and smooth costiB, crossing about eight large 

 longitudinal elevations, which pass rather obliquely from left to right : axis two 

 lines." 



From want of evidence " Tiivho " varicosus was not listed either by Morris
