Vol. i. p. 107. Genus BUCCINUM. 



Sub-gen. volutiiarpa, Fischer. 

 Shell ventricose, thin; spire short; aperture very large. />'. 

 Deshayesianum, Fischer, is an example. 



Vol. i. p. 110. Genus COMINELLA. 



M. Duuker has proposed a new genus, under the name of 

 Adamsia. It is closely allied to Cominella, of which it may be 

 considered a sub-genus, differing from the typical species in 

 being without the posterior callus. C. typica, Duuker, is 

 an example. 



Vol. i. p. 122. Genus TEINOSTOMA. 



The species anomahim, C. B. Adams, should be pusillum, 

 C. B. Adams, and Vitrinella minuta, C. B. Adams, also belongs 

 to this genus. Mr. P. P. Carpenter has since described two 

 other species, amplectans and substtiatlum, and he considers the 

 genus to be allied to Umboniwn, in which opinion, upon a fur- 

 ther comparison of the shells, we are inclined to agree, and to 

 transfer it accordingly to the sub-family Umhoniince. 



Vol. i. p. 145. Genus OLIVELLA. 



It is stated by Dr. Gray that OUvella (Lamprodoma) volu- 

 tella is not furnished with an operculum, in which case the sub- 

 genus Lamprodoma, of which Bamola, Gray, is a synonym, must 

 be kept as a genus". 



Vol. i. p. 157. Fam. VOLUTIDiE. 



The following arrangement of the Yolutidte has recently been 

 proposed by Dr. Gray.
