LEODICID^B OF THE WEST INDIAN REGION. 



13 



The fifty-first parapodium (text-figure 5) resembles the tenth in general outline, 

 but all parts are smaller and ventral aciculse have made their appearance. In a later 

 parapodium (text-figure 6, the tenth from the pygidium) the post-setal lip is pointed 

 at the apex and the ventral cirrus has lost its swollen base. 



The anterior parapodia have each two or three aciculse with bluntly rounded apices. 

 By the fiftieth parapodium two others appear, lying ventral to the former variety, each 

 with terminal and subterminal teeth (text-figure 7) and with a hood covering its apex. 

 Both forms of aciculaa occur in all parapodia posterior to these.
