174 M. O. A. L. MORCH's REVIEW OF THE VERMETID^. [April 9, 



whether this is specifically distinct, the var. a showing a transition. 

 A part of the keel shows some small, equidistant brown spots Uke 

 those of the preceding variety. 



Serpula vermetus of Sowerby's ' Genera,' seems to be most nearly 

 allied to var. a, chiefly by the spire. The operculum represented in 

 the mouth of the shell, and the much smaller free specimens, are 

 very likely rather inaccurate.

The spire of this shell is still larger, as in the quoted figure. I 

 have never seen a depressed aperture, as in Woodward's plate ; but 

 a somewhat similar one is to be seen in Schwammerdara (t. 7. f. 5, 6).
