I must refer to the figures 4 and 5 to explain the form of tlie most 

 curious caudicle and gland of tins species, which it must be difficult to 

 understand from the description. A moditication of it is given afc 

 figures 5 and 6 of PJ. 2175, and it will be seen that both are extreme 

 developments of that represented at fig. 5 of PI. 2174. — J. D. H.
