Mr. R. E. Turner on 
upper latus, and scutwm are present, and the inner surface of the 
right scutum (s) and that of many of the subscutal scales of 
the peduncle can av seen projecting from beneath the opposing 
series. Circa X 2 diam. 
(Figs. 1 and 2 represent the three syntypes of Zoricula 
darwint, H. Woodward, all three shells being muck flattened 
transversely.) 
Fig. 3. A shell (the holotype of Z. pulchella, G. B. Sowerby, Jun.) with 
the outer surface of the deft side uppermost, and showing 
the scutum (s’), upper latus (w’), and carinal-latus (c/’), the 
carina and tergum being absent from the capitulum. This shell 
has a much greater transverse convexity than those represented 
by figs. 1 and 2. Circa x 3 diam.

Stramentum haworthi, 8. W. Williston, sp. Senonian 
(Niobrara series): Kansas, U.S.A. 
Fig. 1. Remains of two immature individuals. A, the right side of a 
shell with the inner surface uppermost, the carina only missing 
of the capitular valves, and the scutum (s) shows the adductor 
muscle-pit ; the peduncle has only twelve scales. B, the lower 
part of a peduncle with its inner surface exposed. C, capitular 
valves probably belonging to B, and consisting of the linear 
carina (c), the right carinal- latus (el), left upper latus showing 
inner surface, and paired scuta (s), the deft seutwm being broken 
and exposing ‘the right scutum beneath. Circa X 6 diam. 
Fig. 2. A fine example of a shell lying on its right side, and owing to 
the displacement of the capitular valves both the left and right 
vaives can be seen, the right scutum (s) showing the adductor 
muscle-pit ; the peduncle in the main shows the inner surface 
of the three median series of scales of the r ight side of the shell, 
except that the whole of the left carimo-lateral scales (cls’) 
are present. Circa x 4'5 diam. : 
Fig. 3. A shell with the right side uppermost and showing the whole of 
the capitular valves, the carina (c) being somewhat incomplete.
