is distinguished bj the form of the mouth, and character of the 
septa/' (Morris and Lycett,) 
Remarks. This species bears some resemblance also to Nautilus 
suhtruncatus, M. and L., but it is a more compressed shell, and not 
so short and thick as the latter. The specimen of N. Baheri de- 
scribed by Morris and Lycett must have been badly preserved, as is 
usually the case with the Minchinhampton fossils, because those 
authors describe the species as having a smooth shell, only slightly 
marked by the lines of growth, whereas the test (fragments of 
which are preserved upon some of the specimens in the British 
Museum bears numerous very strong irregular transverse folds, 
resembling those of N. suhtruncatus., though not so numerous. 
Another point in which these two species differ may be here men- 
tioned, and that is, the present species is narrowly umbilicated, but 
in N. suhtruncatus the umbilicus is entirely closed. 
I am in doubt whether the specimens numbered 19528 (from 
Blisworth) and 20745 a (from Woodford) are rightly referred to 
this species, both specimens being very imperfect ; they show, how- 
ever, strong transverse ridges.
