Two specimens. Clxxxii. Botiu. 11. viii. 1900. Port Island Bay ; shore

There is no need to describe these specimens ; the number of tentacles 

 aud arrangement of mesenteries refer them with certainty to the genus 

 Peachia. It is a little more difficult to speak certainly as to species, because 

 the couchula is not very well preserved, and it is in any case a structure 

 which may lose some of its characteristics after the animal's death. But 

 although it has three more or less distinct primary lobes, these are again 

 Bub : hough not deeply; and it approaches much more nearly the 



conchula of 1 ■ than that of undata hylia. 1 may add that I 



have kept living specimens . and that the conchula of that species 



might well shrink in that it presented tin- form shown in the speci- 



mens under discussion.
