DUN DRY GASTEROPODA. 29 



This is in all probability Eucyclus goniatus, Desl. (Bull. Soc. 

 Linn, de Norm. V. pi. 11, fig. 6) but we should not be justified 

 in citing it as such till better specimens are found. It was described 

 from the same horizon as our example. 



Locality — Dundry. Inf. Ool. 



AMBEELEYA, sp. 



We have an incomplete shell 5b mm. long, and 40 mm. broad, 

 which may probably be referred to T. ornatus, Goldf. (non Sow.) 

 Petr. Germ. tab. 194, fig. 2. 



The last whorl is almost devoid of shell, but shows on the cast 

 the two chief strong keels, and above them two more ; these are 

 seen to be spiny where the shell remains. On the penultimate 

 whorl [are seen two strong keels, and two lesser spiny ridges 

 above them, while below is a beaded line close to the suture. 



It seems to diff'er from Sowerby's species, and the whorls are 

 more convex or circular in outline. 



The mouth and base of last whorl are unfortunately not 

 preserved. 



Locality — Dundry. Inf. Ool. 



TUEBO STODDAETI, n. sp. PL 2, fig. 1. 



Length, if complete, 22 mm; breadth, 17 mm. 



Shell turbinate ; whorls convex, ornamented with numerous 

 fine ridges, alternately stronger and fainter; the more pronounced 

 set with round knobs or tubercles, the intermediate lines with 

 much fainter longitudinally compressed dots, which however are 

 sometimes absent; towards the base of the last whorl the 

 intermediate lines vanish. There are very faint transverse 

 growth-lines, slightly oblique in direction. 



Our specimen does not show the mouth, but it is apparently 

 not umbilicate. It difi'ers from T. cyclostoma, Zict. (Goldf. tab. 

 193, fig. 7) by the alternate arrangement of the markings; 

 neither can it be identified with T. Rutteri, Moore, (Somerset IST.
