[peripher}’] in a rounded edge, which is ornamented with a row of 
thick elongated rib-like tubercles, extending halfway down the 
height of the whorl. There are about fifteen of these tubercles on 
a specimen which has a diameter of 16S mm. The lateral parts 
[sides] of the whorls slope down from the external edge regularlj’ to 
the umbilical suture, only showing a slight curre, without forming 
any umbilical edge or a distinct umbilical wall. 
“ The septa of this species are slightly curved, like those of the 
preceding one Fleminjianus, de Koninck], but thej’ are 
much less numerous. Besides this, there is no relation between the 
air-chambers and the tubercles, as is the case in Faut. Flemingianus. 
The specimen I have got for description is not snfiiciently well pre- 
served to count the number of septa on each whorl, hut there may 
have been about thirty-two on the last circuit [volution]. 
“ The position of the siphon could not be ascertained. . . 
Nautilus Goliaihus is most nearly allied to the species de- 
scribed by de Koninck under the name of Nautilus Flemingianus 
as already noticed more in detail ^. . . . The differences which exist 
between the two species . . . consist in the greater thickness of the 
whorls, the different arrangement of the septa, and the compara- 
tively smaller umbilicus of Nautilus Goliathus. Prom Nautilus 
tuberculatus, Sow., and Nautilus Molleri^ our species is also 
easily distinguishable by the much smaller umbilicus and the 
greater thickness of the whorls. Of foreign species only Nautilus 
(Eiidolohus) spectahilis, Meek and Worthen, bears a certain resem- 
blance, but the transverse section of the whorls in this species is 
quite different from that in the Indian form.” {Waagen.) 
Remarhs. Dr. Woodward having written to Dr. King (Director 
of the Geological Survey of India) begging that a cast of the figured 
type of Nautilus Goliathus might be made for the British Museum, 
received a courteous reply from Mr. F. B. Mallet to the effect that 
the figured type itself had, with the consent of Dr. King, been 
forwarded ; accordingly T am now enabled to compare it with the 
fine example in the British Museum (Xo. C. 357).
