HIND : NEW CARBONIFEROUS NAUTILOIDS. 105 
a character which shows that it belongs to the genus Ephippio- 
ceras, Hyatt. Wild, in the same paper, refers erroneously to 
N. cyclostomus, a large shell, which is now shown to be Soleno- 
cheiliLS, and erected into a new species, ^S*. glohosus (p. 98). E. Wildi, 
has been collected from a number of localities, all on the horizon 
of the Bullion Coal or Mountain Mine. Two other species of this 
genus are known from beds of Coal Measure age in England. 
Ephippioceras clitallarium, J. de C. Sow., Trans. Geol. Soc, Vol. v., 
Pt. iii., PI. xl., figs. 5, 5a, 56. Hind (Stobbs and Hind), Q.J. Geol. 
Soc, Vol. Ixi., p. 541, and E. costatum, Foord, Cat. Foss. Ceph. 
Brit. Mus., Vol. ii., p. 103, fig. 14, both of which are much more 
globose, much smaller and more involute, the median saddle of 
the suture is broader and comparatively less elevated, and the body 
chamber shorter and more expanded transversely. 
E. bilobatum, Sow., sp., occurs in the (?) Calciferous sandstone 
series of Closebum, Dumfriesshire ; it is more nearly related to 
E. clitellarium, Sow., sp., than to E. Wildi in general shape. 
I have referred a specimen in my collection from the IVIill- 
stone Grit of Hazel Hill, near Ripon, to E. bilobatum, but there is 
no doubt that the genus is present at that horizon (Life Zones in 
Brit. Carb. rocks, Naturalist, 1907, p. 17). 
There occurs in the Silica quarry at Congleton Edge, almost 
600 feet below the base of the Millstone Grit, a marine band in the 
zone of Glyphioceras spirale, a large Ephippioceras with a some- 
what acute saddle in the suture, not E. Wildi, but owing to the 
fragmentary condition of this specimen, I hesitate to speak 
more definitely at present. This genus is represented in the 
Coal Measures of Kentucky, U.S.A., by E. ferratus, Cox, sp. 
(Geol. Soc. Kentucky, Vol. iii., p. 574). Hyatt refers Nautilus 
divisus, White and St. John (Descr. Fossils, etc.. Trans. Chicago 
Acad., Sec. i., p. 124), from the Lower Coal Measures of Kansas 
and Texas to Ephippioceras. This form is somewhat larger than 
E. Wildi, the body chamber more transverse, and the saddle of 
the suture broader and less elevated. 
Nautilus montgomeryensis, Worthen, Geol. Surv. Illinois, 
Vol. viii., p. 148, PI. xxvi., fig. 2 ; PL xxvii., fig. 1, from the Coal 
Measures of Illinois, has a median saddle more Hke that of E,
