Sparingly represented at all the Stations and presenting no special featm-es 

 excepting at Station 6 (N.Z,). Here the type occurs, but less abundantly than 

 the moniliform variety originally described by d'Orbigny from a figure of Cornuel's as 

 Webbina irregularis (q.v. j^ost). The difference in the shape of the chambers makes 

 it worth while recording this as a separate form, though there can be little doubt 

 as to the zoological identity of the specimens.

Station 6. 



Attached to stones and differing from IT', clavata in the smaller size of the, 

 chambers, their pyriform shape, and the arrangement in a continuous chain of 

 three or more segments, often variable in shape, adapting themselves to the 

 contour of the host. Constructed like W. clavata, of line sand with a maximum 

 of reddish cement, colour varying as in that species, from pale yellowish-grey to 

 deep brown. 



It is extremely interesting to find this form, hitherto exclusively knomi as 

 a fossil, from the Lias upwards, in the recent condition. The N.Z. specimens 

 differ from Cornuel's original figure, and subsequent figures, in the length of the 

 stolon-tubes between the successive chambers. In some instances the stolon is 

 as long as the chamber itself. The nearest approach perhaps, is the specimen 

 figured by Costa, ut supra.
