shape, thick and nodulous varices, closely appressed spines, and the 
decided lateral direction of the canal. 
Typuis arcuatus. Typ. testd corned, fusiformi ; quadrifariam va- 
ricosd ; varicibus arcuatis, inermibus, ad spiram bene distinctis, 
superne in tubulis desinentibus ; tubulis complanatis, ascendentibus ; 
canali mediocri recurvo. Axis 5} lin. 
Hab. Cape of Good Hope. Dredged on the L’Agulhas Bank in 
from forty to fifty-four fathoms. 
Shell fusiform, of a horn-colour; the varices arcuate, terminating 
in the tube, and ascending the spire even to the apex, giving ita 
pyramidal shape. The character of the bowed spineless varices is 
peculiar, and altogether it is a very distinct species. 
Typuis nitens. Typ. testd ovali, albidd, levigatd, nitidd ; quadri- 
fariam varicosd ; varicibus acutis in spinis excentricis desinentibus ; 
tubulis rectis ; canali brevi recurvo. Axis 4 lin. 
Hab. Straits of Macassar, Indian Archipelago. Dredged from 
among gravel and coral in eighteen fathoms. 
Looking from the apex, the spines and tubes will be seen to be 
disposed in an elegant spiral manner about the spire. It is the first 
species, as far as I am acquainted, that has hitherto been found in 
the Indian seas, and is at the same time the smallest yet recorded. 
A communication from Prof. Owen was read, proposing to substi- 
tute the name Dinornis* for that of Megalornis, applied to the Great 
Bird of New Zealand in his paper read at the previous Meeting. The 
change is rendered desirable, to prevent confusion in nomenclature, 
Mr. G. Gray having previously used the term Megalornis for a genus 
of Birds in his ‘ List of the Genera,’ &c. 
* From dees, prodigious, and deus, bird. This change in the name has 
been made in the paper referred to whilst passing through the press.
