kind of network. The calycles are 

 exceedingly minute, and of equal 

 width throughout, till within a short 

 distance of the base, when they are 

 abruptly rounded off; they are of a 

 somewhat dense corneous texture, 

 and preserve their shape well when 

 dried (Woodcut, fig. 24).

STEM creeping; HYDROTHEC^E minute, tumid beloiv, with 

 the sides curved inwards above, and expanding again 

 slightly towards the top, aperture entire, borne on rather 

 long, ringed pedicels ; GONOTHECLE unknown. 



THE very graceful outline of the calycle distinguishes this 

 species from all the other British members of its genus, 

 amongst which the prevalent form is cylindrical or simply 

 tubular. It resembles a very elegant little goblet mounted 

 on a twisted stem. In the hydrotheca of L. pocillum the 

 lower half is the widest portion ; above it the sides are 

 incurved, but they expand again towards the aperture. 

 The length of the pedicel varies ; it usually consists of 6 

 or 7 rings, but is occasionally longer.
