SHELL more ventricose than the typical form, with a 
shorter spire ; WHORLS five, more convex, the last whorl eon- 
stituting almost the whole of the shell ; APERTURE longer in 
proportion than that of the type, and exceeding the spire in 
leneth. owing probably to the shell not having attained 
maturity. 
Leneth of shell, 40 mill. ; diam. 25 mill.

Glandina convexa (S. V. Wood), Sconce, Isle of Wight ; photographed by Mr. J. G. Randall, 
slightly reduced. 
G. convera varies considerably in size. Of the two specimens figured, the 
larger shell, indicated by the black spot on the body whorl (fig. 46) is the 
identical individual selected as type by Searles V. Wood for illustration in 
the Memoirs of the Paleeontographical Society; its total height before loss 
of apex was probably 45 mill., as even now, after mutilation, it attains 40 
mill.; its breadth is 21 mill. ‘he aperture is 20 mill. long and 10 mill. in 
diameter. he smaller specimen (fig. 47) is 36 mill. long, and 17 mill. 
broad ; its aperture 18 mill. long and 10 mill. wide.

1 Geologists speak of Sconce as if it were a geographical place. Sconce is a common noun, meaning a 
fort (to ensconce was to retire into the sconce for defence), and was applied to the defences of Tudor and 
Stuart times, which were often distinguished by the names of the erectors. This one is marked on some 
maps as Cary’s Sconce (now demolished). The Bembridge limestone is exposed near its site, hence its 
notoriety, C. Ashford in litt., 1890,
