about one half the diameter distant ; deeply concave. Siphiincle 
central, cylindrical, rather large. Bod 3 ^-chamber unknown. 
Remarks. All the specimens are very imperfect, so much so that 
Sowerby adds to his brief description that the name of the species 
must be considered only as temporarj’. 
Horizon. Middle Devonian. 
Locality. Mudstone Bay, near Torquay, Devonshire. 
Fairly well represented in the Collection by specimens presented

Sp. Char. “General figure elongate conical, but near the aperture 
somewhat fusiform; surface (?) ; section elliptical, with diameters 
as 10 to 12 ; septa oblique, waved, distant *27 to *35 diameter, 
rather shallow ; siphuncle eccentric (on, or nearly on, the conjugate 
axis).” {Phillips.) 
Remarks. I have referred a specimen, consisting of a polished 
section only, with much doubt to this species. The septa are very 
close, their distance being from L to the diameter. The rate of 
increase is apparently rather rapid, about 1 in 6.

Orthoceras, sp. 
Fragment of a large Orthoceras, measuring about 2| inches in 
breadth ; the septa distant about 5| lines or i the diameter (?). 
The siphuncle cylindrical, about 2| lines wide. The specimen is 
crushed and flattened, so that its natural shape cannot now be made 
out. It may be compared with Phillips’s figure 204 h on pi. xli. 
(Joe. cit.).

Locality. Hope’s Nose, near Torquay, Devonshire.
