an idea. The form and structure of the nucleus are entirely unlike 

 that of the genus Amoria. The shell is entirely destitute of any 

 polished coat, which is the character of that genus, as is proved hy 

 the examination of the body whorl near the inner lip ; for, though the 

 very thin inner lip is almost entirely destroyed, yet the groove which 

 indicates its extent is well marked by a rather broad impressed line, 

 denning its limits and showing that it was not even extended over 

 the lower part of the body whorl of the shell, much less over the 

 extreme surface of it. 



SCAPHA MARIA-EMMA. (PI. XLVIII.) 



Shell ovate, fusiform, pale brown, with narrow, deeply-waved, lon- 

 gitudinal, dark brown lines, forming four more or less distinct, inter- 

 rupted, spiral bands, consisting of the broader and straighter portions 

 of the longitudinal lines ; nucleus large, subcylindrical, with a re- 

 gular spiral, smooth and rounded apex, without any crenulation near 

 the suture ; spire conical ; whorls rather ventricose ; outer lip rather 

 arched. 



Hab. ? 



I have named this fine species after my wife, Maria-Emma Gray, 

 whose work, entitled ( Figures of Molluscous Animals for the use of 

 Students,' having brought the figure of the animals of a large number 

 of shells within the reach of students, has entirely changed the pre- 

 vious condition of the science of conchology (as is proved by the 

 works of Adams, Philippi, Weigmann, and other Malacologists) ; and 

 who was an industrious collector of shells and mollusca before our 

 marriage, now many years ago. 



We have also received a Volute from Mr. Cuming which has been 

 lately described at Paris under the name of Voluta rossiniana. It 

 has a large nucleus, with a large rounded apex of regular smooth- 

 edged whorls. It will be called in the Museum Scapha rossiniana. 



I have also seen a young Volute from New Zealand, which is very 

 like Volutella papillosa ; but the shell shows no sign of the expanded 

 mantle, which may only be expanded in the adult state of the animal. 

 It differs from the specimen of V. papillosa in the British Museum 

 in the nucleus being shorter and of fewer, only one and a half, 

 whorls, though it agrees with those shells in the apex being rather 

 excentric, and the outer edge of the upper or apical whorl being 

 blackish. 



The shell is much more ventricose, and the spire shorter, than in 

 the usual form of V. papillosa. It may be only a variety of that 

 species, but other specimens are wanting to determine this point.
