350 M, O. A. L. MORCh's review of the VERMETIDiE. [Nov. 12,

 Notwithstanding that the sculpture is very different, I place it 

 for the present in this species. In respect to the sculpture, it 

 corresponds to var. y of V. varians, D'Orb., and to var. i of forma 

 electrina, as regards size.

 Hab. Australia {coll. Cuming, Catpenter). 



In Mr. Cuming's group, which appears to be bleached, were found 

 a Rissoa, and a 5 m. long. Crypta aculeata, Chemn., or one of the 

 species generally confounded with it. As the latter shell is not known 

 to me as Australian, I suppose the locality assigned to the species is 

 erroneous. 



Among the worm-tubes which, through the kindness of Professor 

 Grube, I have on loan, is a group very like that of Mr. Cuming ; 

 but I could not discover any sections corresponding to Mr. Carpenter's 

 drawing, although they approached very much to Mrs. Adams's figure, 

 which seems to be taken from the Cumingian group. It is evident 

 to me that the size of the chambers is not constant in one and the 

 same specimen, as a comparison of Carpenter's and Adams's draw- 

 ings, both very exact, sufficiently proves.
